Rivian May Redesign Its Doors After Tesla’s Cybertruck Lawsuit Fallout

https://www.autoblog.com/news/rivian-may-redesign-its-doors-after-teslas-cybertruck-lawsuit-fallout

A Growing Concern Around Electronic Door Handles

Automakers have steadily moved toward electronic door handles in the last decade, trading traditional mechanical latches for sleeker, more aerodynamic solutions. The design trend appeals to both styling and efficiency goals, but it has also introduced new safety concerns. Manual emergency releases are often tucked away or difficult to locate, raising questions about how quickly occupants can exit a vehicle in an emergency.

Rivian is taking these concerns seriously as it prepares its R2 SUV for launch next year. Following feedback from employees and customers, the company is revising its interior door layout. According to Bloomberg, the manual releases will be positioned closer to the powered handles in a more visible spot, making them easier to identify and operate.

The move comes at a time when door handle design is under heightened scrutiny, particularly after a lawsuit tied to Tesla’s Cybertruck has brought the issue into sharper focus.

The Cybertruck Lawsuit and Its Fallout

Tesla is facing litigation in California state court over a fatal Cybertruck crash in Piedmont late last year. According to Automotive News, four people were involved in the incident, with the Cybertruck reportedly traveling over 80 mph when it left the road. It then collided with a tree and a retaining wall, and caught fire. Three occupants died of smoke inhalation, while one passenger was rescued after a friend broke the window.

Families of two victims, 20-year-old Jack Nelson and 19-year-old Krysta Tsukahara, argue that design flaws in the Cybertruck’s doors turned a survivable crash into a fatal fire. The Cybertruck does not use traditional handles; its exterior doors are opened with small buttons near the windows, while manual releases inside are difficult to find – not the first time happening inside a Tesla. The plaintiffs also contend that Tesla’s reinforced glass and stainless-steel doors made escape or rescue attempts significantly harder.

The lawsuit states that Tesla is aware of the problematic door design, but chose to ignore it. Trials for the suit are scheduled to begin in 2027.

The Ford Mustang Mach-E Recall

Tesla is not the only automaker facing issues with electronic door latches. Ford recently recalled nearly 200,000 Mustang Mach-E electric crossovers in the United States, with an additional 120,000 affected abroad due to a similar issue. According to filings with the National Highway Traffic Safety Administration (NHTSA), a weak 12-volt battery could cause the doors to remain locked after being shut. In some cases, the cars would not unlock even when jump-started.

Ford acknowledged that the problem could trap passengers inside or prevent access to children left in the vehicle. One report surfaced of a baby stuck in a Mach-E for nearly 40 minutes before being freed. The company has issued a stop-sale order and will address the issue with a software update.

https://www.engadget.com/big-tech/two-amazon-prime-air-drones-crashed-in-arizona-224857013.html?src=rss

Two Amazon delivery drones reportedly collided with a crane this morning in Tolleson, AZ. The incident occurred about two miles from a fulfillment center run by the tech company and involved two of its Prime Air drones. No injuries have been reported. Law enforcement were called to the scene, however Sgt. Erik Mendez of the Tolleson police told local radio station KTAR that the Federal Aviation Administration would be taking over the investigation.

"We’re aware of an incident involving two Prime Air drones in Tolleson, Arizona," Amazon representative Terrence Clark said. "We’re currently working with the relevant authorities to investigate."

Amazon began offering a drone delivery option in the Phoenix area last year. The drones only fly during the day and if weather conditions are favorable. The company received FAA approval to ship several more products by drone in May.

Could Daydreaming at Work Unlock Your Best Problem-Solving Skills?

https://www.discovermagazine.com/could-daydreaming-at-work-unlock-your-best-problem-solving-skills-48090

At school or in the office, mind wandering is often frowned upon. Students are told to “snap out of it,” and employees are nudged back to focus on the task at hand. Yet new research suggests that with the right support, what looks like distraction might in fact be a powerful tool for solving tough problems.

A joint team of researchers from the U.S. and the Netherlands has found that curious individuals who allow themselves to daydream around work challenges are more likely to experience strong epiphanies. These flashes of insight can not only spark innovative solutions but also renew a sense of meaning in their careers.

“For years, I was fascinated by the phenomenon of epiphanies, but I wasn’t sure how to study them, and I found the challenges that go with pursuing a new and uncharted line of research a bit daunting,” said Erik Dane, professor of organizational behavior at Olin Business School at Washington University, in a press release.

The team’s findings, published in the Journal of Management, may even encourage workplaces to consider workshops that embrace mind wandering as a path to those light-bulb moments.

Epiphanies and Curious People Who Daydream

The research involved business administration students, alumni, and aspiring business leaders in three different studies. Participants were assessed for their ability to have work-related epiphanies and were guided through professional workshops and individual coaching sessions designed to strengthen leadership skills.

Exercises encouraged students to reflect on key life events, the legacies they hoped to leave, and even their own mortality. Crucially, participants were also given time to let their minds wander. Daydreaming wasn’t treated as a lapse in focus but as an intentional part of the process.

The results were clear: Participants who allowed themselves to daydream while working through a challenge were more likely to experience meaningful insights. And those naturally drawn to tackling complex problems, typically more curious and motivated to expand their knowledge, gained the most. For them, daydreaming was less about escape and more about finding new pathways forward.

Why Daydreaming Works Well to Solve Problems

“Mind wandering is a particularly useful way to solve problems because it redirects attention away from existing solutions and helps people engage in imaginative thinking, entertaining brand new possibilities,” said Markus Baer, professor of organizational behavior at Washington University, in the news release.

He added that daydreaming provides a more playful and liberating approach compared to conventional, formal problem-solving methods.

Dane agreed: “When you daydream, you’re more likely to let go of assumptions — including unhelpful or outdated beliefs about yourself — and to think in flexible and innovative ways. And this opens the door to experiencing strong epiphanies.”

Sometimes, Dane explained, stepping back to see the bigger picture with a bit of free imagination can deliver not only fresh solutions but also a stronger sense of purpose.

Space for Daydreaming at Work

The researchers argue that organizations and business schools should recognize the value of problem-solving daydreaming by offering workshops and programs to nurture the skill.

Since many people are searching for greater career guidance, this research suggests they may benefit from first looking inward. Instead of waiting for external circumstances to inspire them, intentional reflection and daydreaming could help create the breakthroughs they seek.

“Epiphanies are one of the most memorable and impactful psychological events that people experience in their lives — and my research has helped me understand when and why people experience epiphanies and how epiphanies shape the ways in which people navigate their careers, gain self-confidence, collaborate with colleagues, and serve as leaders in organizations,” said Dane.

Bike Crash Survivor Fuses With Ride to Create Electric Motorcycle Suit

https://www.geeksaresexy.net/2025/09/30/bike-crash-survivor-fuses-with-ride-to-create-electric-motorcycle-suit/

 Electric Motorcycle Suit

Sometimes YouTubers build things nobody asked for, and sometimes they build things we didn’t even know we desperately needed. Case in point: Jake Carlini just turned himself into a wearable electric motorcycle suit. After a tragic bike crash, instead of fixing the poor thing, Jake did the only logical thing: he grafted it onto his own body like a low-budget superhero origin story. What follows is 22 minutes of trial, error, and “please don’t let me electrocute myself,” all leading up to a glorious 30-second payoff where man and machine finally become one.

Watch and be amazed:

Tile trackers reportedly have a security flaw that can let stalkers track your location

https://www.engadget.com/big-tech/tile-trackers-reportedly-have-a-security-flaw-that-can-let-stalkers-track-your-location-183949165.html?src=rss

Researchers have discovered major security flaws with Tile tracking tags, according to a report by Wired. These flaws could allow both the company itself and tech-savvy stalkers to track a user’s location. The security issue could also let a malicious actor falsely frame a Tile owner for stalking, as the flaw can make it appear as if a particular tag is constantly in the vicinity of somebody else’s tag.

The issue pertains to how Tile tags transmit data during use. Tile tags transmit a lot of data beyond that of other trackers, including the static MAC address and the rotating ID. According to reporting, none of this stuff is encrypted. The rotating ID changes all of the time, but a MAC address doesn’t.

Researchers believe that all of this information is stored in cleartext, making it easy for hackers to get ahold of. This also would theoretically give Tile itself the ability to track its users, though the company says it doesn’t have this capability.

It gets worse. Anyone with a radio frequency scanner can allegedly intercept all of this information as it’s being transmitted, creating another potential security hole. Also, this problem might not even be solved if Tile decides to stop transmitting the MAC address. This is because the company generates its rotating ID in such a way that future codes can be reliably predicted from past ones.

“An attacker only needs to record one message from the device," one of the researchers behind the findings said, adding that a single recorded message will "fingerprint it for the rest of its lifetime." The researcher said this creates a risk of systemic surveillance.

The security researchers, who are involved with the Georgia Institute of Technology, reached out to Tile’s parent company Life360 in November of last year to report the findings. Wired said the company stopped communicating with the researchers in February. The company did say it has made a number of improvements to its security but didn’t elaborate further.

It’s a sunny June day in southeast England. I’m driving along a quiet, rural road that stretches through the Kent countryside. The sun flashes through breaks in the hedgerow, offering glimpses of verdant crop fields and old farmhouses.

WIRED’s Guide to How the Universe Works

Your weekly roundup of the best stories on health care, the climate crisis, new scientific discoveries, and more.

Thick hawthorn and brambles make it difficult to see the 10-foot-high razor-wire fence that encloses a large grassy mound. You’d never suspect that 100 feet beneath the ground, a high-tech cloud computing facility is whirring away, guarding the most valuable commodity of our age: digital data.

This subterranean data center is located in a former nuclear bunker that was constructed in the early 1950s as a command-and-control center for the Royal Air Force’s radar network. You can still see the decaying concrete plinths that the radar dish once sat upon. Personnel stationed in the bunker would have closely watched their screens for signs of nuclear-missile-carrying aircraft.

After the end of the Cold War, the bunker was purchased by a London-based internet security firm for use as an ultra-secure data center. Today, the site is operated by the Cyberfort Group, a cybersecurity services provider.

The Cyberfort bunker is a solid inclined mass of grass-covered concrete that emerges in the center of the compound.

I’m an anthropologist visiting the Cyberfort bunker as part of my ethnographic research exploring practices of “extreme” data storage. My work focuses on anxieties of data loss and the effort we take—or often forget to take—to back up our data.

As an object of anthropological enquiry, the bunkered data center continues the ancient human practice of storing precious relics in underground sites, like the tumuli and burial mounds of our ancestors, where tools, silver, gold, and other treasures were interred.

The Cyberfort facility is one of many bunkers around the world that have now been repurposed as cloud storage spaces. Former bomb shelters in China, derelict Soviet command-and-control centers in Kyiv, and abandoned Department of Defense bunkers across the United States have all been repackaged over the last two decades as “future-proof” data storage sites.

The best powered bookshelf speakers for 2025, tested and reviewed

https://www.popsci.com/gear/best-powered-bookshelf-speakers/

Powered bookshelf speakers are having a moment. Once considered a middle ground between bulky component systems and wimpy desktop speakers, today’s powered models pack serious performance into compact cabinets. They don’t need a receiver, they cut cable clutter, and many double as all-in-one multimedia hubs for music, movies, and gaming. Whether you want a sleek hi-fi upgrade, a small-space solution, or something that straddles studio projects and casual listening, we’ve tested the best powered bookshelf speakers released in 2025—like our best overall, the Fluance Ri71—to help you find the best fit.

How we chose the best powered bookshelf speakers

We chose the best powered bookshelf speakers by combining hands-on testing with research from trusted peers. To find the best speakers, we didn’t just skim spec sheets—we listened. Every model here was auditioned with turntables to Bluetooth playing everything from metal to jazz to see how it handled clarity, balance, and low-end punch. We also factored in build quality, connectivity, and day-to-day usability. Finally, we weighed sound and features against price to make sure each pick earns its spot on this list.

The best powered bookshelf speakers: Reviews & Recommendations

With the basics in mind, here are our picks for the best powered bookshelf speakers. Each one brings something unique to the table—whether it’s studio precision, analog format approachability, or a computer-friendly desktop footprint that won’t cramp your style.

Best overall: Fluance Ri71


See It

  • Use AMT tweeters for crisp, airy highs and exceptional imaging 
  • A full-bodied presentation that feels like it should cost much more
  • HDMI ARC input
  • Fabulous price::performance
  • Front ports mean can be placed comfortably close to walls

Cons

  • No optical or USB-C inputs
  • No grilles

Specs


  • Price:


    $399/pr

  • Frequency response:


    46 Hz – 30 kHz (DSP Enhanced)

  • Drivers:


    Air Motion Transformer (AMT) tweeters, 5.25-inch woven glass fiber composite woofers

  • Power:


    120W Class D amp

  • Connectivity:


    HDMI ARC and Bluetooth 5.0 aptX HD, Subwoofer out

  • Dimensions:


    12.20 x 7.28 x 7.83 inches

  • Weight:


    Active Speaker: 14.11 lb (6.4 kg), Passive Speaker: 11.02 lb (5 kg)

Why it made the cut: With refined sound, versatile connectivity, and a design that blends hi-fi flair with everyday usability, the Ri71 is the best all-around choice.

The Ri71 from Canadian brand Fluance stands apart with AMT tweeters, which use a pleated diaphragm to move air quickly and precisely—resulting in crisp, airy highs and exceptional imaging. Pairing those with woven glass fiber drivers and front-facing bass ports, the Ri71 delivers warmth through the mids and punch through the lows, for a full-bodied presentation that feels like it should cost much more than $399. I tested these speakers alongside Fluance’s excellent RT85N turntable while reviewing the best beginner turntables, and was impressed by how expansive and refined they sounded. (Note that the Ri71 has RCA ins but doesn’t include a phono stage, so you’ll need a turntable with a built-in preamp, like the RT85N, or an external preamp.) 

With Massive Attack’s slow-burn trip-hop classic “Protection” on vinyl, the Ri71s highlighted warm, detailed mids that kept the pulsating synths and organic motifs distinct yet cohesive, Tracy Thorn’s rich, angel-on-earth vocals floating above it all in a holographic center stage. The Ri71s exhibited a linear response, staying balanced and articulate across listening levels. HDMI ARC and Bluetooth 5.0 aptX HD support make the Ri71s just as viable for TV sound as they are for vinyl and streaming, and rear-speaker EQ knobs let you dial in the best sound in your space.

Best for detail-obsessed ears: FiiO SP5


See It

Pros

  • Accurate, monitor-inspired sound signature
  • Clear detail and wide stereo image
  • Low-noise, high-precision electronic volume control
  • Versatile for both home studio and living room listening
  • 4-channel amp: 60W*2 woofer / 20W*2 tweeter
  • App with 10-band PEQ and input switching

Cons

  • No phono stage for turntable hookup
  • No subwoofer output for expansion

Specs


  • Price:


    $749/pr

  • Frequency response:


    65Hz-20kHz (standard mode), 50Hz-20kHz (low frequency boost enabled)

  • Drivers:


    5.25-inch composite fiber woofer + 1-inch composite silk soft dome tweeter

  • Power:


    Independent 120W power supplies for clean output

  • Connectivity:


    XLR, RCA, AUX, USB-C, LDAC & aptX Adaptive

  • Dimensions:


    170 x 185 x 280 mm (including feet)

  • Weight:


    6.01KG main speaker, 5.94KG secondary speaker

Why it made the cut: With studio-grade build, surgical EQ control, and an unapologetically revealing sound signature, the SP5 is for listeners who want to hear everything—and tweak it to taste.

Best known for audiophile DACs, DAPs, headphones, and IEMs, FiiO has been edging into speakers for years. The SP5 represents its most ambitious effort yet: a flagship bookshelf system with serious studio DNA. Each speaker runs on its own dedicated 120-watt supply—a design more often seen in high-end separates than desktop systems. That dual-supply architecture keeps power delivery clean and stable while reducing crosstalk, so each channel stays precise even at high volumes. Inside the Genelec-style cabinet, a four-channel amp sends 60 watts to the woofer and 20 watts to the tweeter, giving both drivers the headroom to perform at their best. The 5.25-inch Rohacell woofer keeps the low end fast and controlled, while the silk dome tweeter extends smoothly into the highs. True to its monitor-inspired DNA, the SP5 doesn’t flatter the mix so much as reveal it: Vocals sit forward, imaging is expansive, and subtle details rise to the surface. 

Listening to Taylor Swift’s Fortnight, the SP5s presented vocals forward in the mix, with smooth mids, bass that stays tight and controlled, and airy, extended highs—even if the highs leaned ever so lifted. On Khruangbin’s Mariella, Leon Bridges’ voice came through with striking clarity, while the soundstage unfolded with depth and separation that still felt cohesive. Straight out of the box, the SP5s sounded accurate and revealing, and their dual power amps and crossovers gave the mids extra control. With the FiiO app’s surgical EQ, you can then fine-tune for placement quirks or dial the presentation exactly to taste. The FiiO Control App unlocks 10-band parametric EQ and other granular controls, while built-in trigger input support lets the SP5 power up in sync with the rest of your gear—equally handy in a studio rack or home system. Add in extensive wired I/O plus LDAC and aptX Adaptive for high-res Bluetooth streaming, and the SP5 checks all the boxes for both creator workflows and living room listening.

Best monitor-inspired sound: KRK Kreate K5


See It

Pros

  • Studio-inspired tuning with wide, clear imaging
  • Bass is articulate but not overhyped; adjustable via EQ
  • Solid build and flexible connectivity
  • Rear EQ trims for room/boundary compensation
  • Bi-amped Class D amplification 

Cons

  • Rear port needs breathing room from walls

Specs


  • Price:


    $169/ea

  • Frequency response:


    58Hz-40kHz (±3dB)

  • Drivers:


    5-inch glass aramid woofer with rear port and 1-inch soft-dome tweeter

  • Power:


    45W LF power amp + 15W HF power amp for clean output

  • Connectivity:


    XLR, TRS, RCA, and Bluetooth 5.3

  • Dimensions:


    14.6 x 12 x 10.3 inches

  • Weight:


    11.5 pounds (total)

Why it made the cut: The compact KRK Kreate K5 blends the brand’s iconic Rokit DNA with a more balanced, versatile voicing—making it equally at home in a creator’s studio or a casual listening setup.

KRK’s Kreate K5 draws directly from the company’s Rokit studio monitor lineage—a family I  know well, with Rokit 8 G3s in my studio rotation for the past decade. While KRK monitors— instantly recognizable by their iconic yellow cones—were historically known for a somewhat bass-prominent signature that’s beloved by EDM producers and artists, the newer Kreate series, representing KRK’s effort to bridge the gap between its iconic studio monitors and more versatile, everyday listening setups, leans more balanced. The result is surprisingly punchy bass for the size; natural yet forward mids and highs, and a soundstage that feels super expansive.

On Prince’s Sign O’ The Times, the K5s laid bare the track’s relatively stripped-down, Fairlight synth-centric production with wide imaging and tight, defined bass—more studio-honest than hi-fi hyped. With a rear port, the K5 boundary EQ trims let you tailor the low end while keeping the overall voicing clear and neutral. At just $169 each (remember to buy two), the K5 is a budget-friendly way to bring studio-grade clarity into a desktop setup. If you seek room-filling sound for a larger space, consider KRK’s 8-inch Kreate 8 ($299/ea); if you’re in a bedroom or dorm room, the ultra-compact (and, at $179/pair, ultra-budget-friendly) Kreate 3 might be just right for you.

Best value: Edifier MR5 2.0


See It

Pros

  • Expansive soundstage with surprising low-end reach
  • Flexible EQ to tweak for room or taste
  • Rear EQ filters and 10-band app control
  • Supports two Bluetooth devices at once
  • Tri-amped design for clean separation

Cons

  • Midrange can sound a little boxy at times

Specs


  • Price:


    $349/ea

  • Frequency response:


    46Hz-40kHz

  • Drivers:


    Patented 3-way driver architecture (5? long-throw woofer, 3.75? mid driver, and 1? silk dome tweeter)

  • Power:


    110W RMS Class D amplifier

  • Connectivity:


    Bluetooth 6.0, plus XLR, TRS, RCA, AUX inputs, and front-panel 3.5mm headphone output

  • Dimensions:


    11?D x 6.3?W x 10.4?H

  • Weight:


    366.4 ounces

Why it made the cut: Edifier’s MR5 is a true crossover pick—musical enough for hi-fi listening, but neutral enough for creators who need an affordable entry point into production.

Edifier has a long track record of making powered speakers that punch above their price, and the MR5 is the latest in that lineage. Marketed as both a studio monitor and a hi-fi speaker, it’s built to play double duty—and it mostly nails it. The design centers around an unusual acoustic architecture that combines a downward-facing 5-inch woofer with a front-facing midrange driver and silk dome tweeter, each powered by its own amp. Side ports help the bass breathe, giving the MR5 more low-end presence than you’d expect from such a compact box, while the mids and highs stay cleanly separated. The presentation leans mostly linear, though the more neutral voicing can feel a little restrained at the lowest volumes. 

On Taylor Swift’s “Fortnight,” the soundstage felt expansive and lushly layered; on Metallica’s “Sad But True,” some of the weight dropped off when I turned it down. Out of the box, the mids can lean a tiny bit boxy, but there are plenty of ways to tweak—rear-panel shelving filters, three listening modes, and the Edifier ConneX app with a full 10-band graphic EQ. Bluetooth 6.0 lets you pair two devices at once, and Hi-Res certification with LDAC streaming rounds out audiophile-loved features. With all this tech in a solid MDF cabinet, the MR5 is classic Edifier: affordable, versatile, and tuned for both creators and everyday listeners.

Best for small spaces: Onkyo GX30-ARC


See It

Pros

  • Elegant, desk-friendly build
  • Packed with inputs and outputs
  • Pairs nicely with turntables to computers
  • Tight, controlled bass
  • Magnetic grilles + angled stands

Cons

  • Limited low-end power

Specs


  • Price:


    $349/ea

  • Frequency response:


    55Hz-20kHz

  • Drivers:


    3.5-inch woofer and 0.75-inch soft dome tweeter

  • Power:


    50W (17W LF+8W HF/ch)

  • Connectivity:


    HDMI ARC, analog, and headphone connections, Subwoofer out 

  • Dimensions:


    5.75“ (146mm) x 10.55” (268mm) x 8.27” (210mm) w/ stand

  • Weight:


    Primary: 6.0lbs (2.7kg) – Secondary: 5.3lbs (2.4kg)

Why it made the cut: Onkyo’s GX-30ARC brings the brand’s 75-year hi-fi pedigree to the desktop, pairing balanced sound with a feature set that includes HDMI ARC, phono-ready inputs, and even a subwoofer output—all in a compact, stylish package.

Onkyo has been shaping the way people listen to music since 1946, with a legacy spanning everything from iconic receivers to beloved hi-fi speakers. After a quieter period, the brand re-entered the market in 2025 under Premium Audio Company, launching the budget-friendly Creator Series and the premium Icon Series. The GX-30ARC is part of the Creator lineup, but despite its entry-level billing, it’s surprisingly full-featured. Magnetic grilles and angled stands add polish, while the compact design hides a surprising amount of tech. Dual amps power a 4-inch woofer and three-quarter-inch tweeter for a clean, detailed sound signature—tight in the bass, smooth in the mids, and balanced across the range. 

Playing pop at desk-friendly levels, the GX-30ARC revealed clear vocals and a soundstage that felt bigger than the boxes. Bass rolled off, but lows were taut and lively, giving tracks body without boom. When pushed hard, the Onkyos could sound a little strained, but for everyday desktop listening, they hit harder than their size suggests. Add in HDMI ARC, USB-C, optical, Bluetooth, plus phono-ready RCA inputs (making them turntable-friendly speakers), and the GX-30ARC covers just about every connection. One quirk to note: The speakers auto-power down after 15 minutes of silence, which can be a little annoying if you’re pausing between sessions. For $349, however, the GX-30ARC offers heritage-backed sound and modern flexibility in a compact, computer-friendly package.

The LS50 Wireless II is available in signature KEF Carbon Black, Titanium Grey, Mineral White (pictured), and Crimson Red finishes, with optional matching stands. KEF’s striking, copper-hued Uni-Q driver orients a 1-inch vented aluminum-dome tweeter in the acoustic center of a 5 ¼-inch magnesium-aluminum alloy woofer cone to create a wide listening sweet spot; a bass-reflex cabinet with elliptical rear ports is designed to maximize accurate, musical low end. And Metamaterial Absorption Technology (MAT) behind the proprietary 12th-generation drivers takes in unwanted reflections and reduces distortion. Detailed and dynamic, the LS50 Wireless II is spacious and gripping; depending on the track, it will sweep you up or float you away. Your preference when it comes to these equally adept two-way challengers may come down to whether your listening leans nimble/bright versus natural/rounded.

The LS50 Wireless II supports lossless, Hi-Res Audio; network file support is 24-bit/384 kHz; a wireless setup supports 24-bit/96 kHz audio resolution or connect the speakers with the supplied CAT 6 cable for 24-bit/192 kHz support. Stream music directly over Bluetooth or Wi-Fi, AirPlay 2, and Google Chromecast, or through the KEF Connect app, which supports Spotify Connect, Tidal Connect, Qobuz Connect, Amazon Music, and Deezer. In addition, you can use the LS50 Wireless II as an endpoint if you set up a Roon music library on your local network. Wired connections include HDMI eARC, Ethernet, coaxial and optical inputs, a subwoofer out, and 3.5mm aux-ins.

The LS50 Wireless II is pricey, typically retailing for $2,999/pair, plus $449 for optional S2 floor stands. (Willing to sacrifice some features to save some money? KEF also makes a baby-in-size-not-sound brother speaker system, the $1,499 Wi-Fi-connected LSX II.) But if you crave a highly resolving, deeply engaging experience and your budget supports it, the LS50 Wireless II’s versatile connectivity options and potent sound make it an ideal all-in-one listening system. If you’re looking to build a wireless surround sound system, they would even act as rear channels if you purchase the KEF XIO soundbar (and they roll out a promised firmware update). And they’re a “bargain”—even if you toss in the sonically and aesthetically complementary $1,699 KEF KC62 subwoofer (shown on the right above)—considering stepping up to the richly evocative, surprisingly slimline KEF LS60 floorstanding powered speakers costs $5,999!

Why it made the cut: Kanto Audio has quietly been making some of the best “bang-for-the-buck” bookshelf-style speakers for some time, but with the Ren, the company is taking things in a new direction.

The Kanto Ren isn’t your average pair of speakers. While they can function that way, and sound very good for pure music, the ace up its sleeve is its HDMI ARC input. This allows it to connect to accept audio directly from a TV, just like a soundbar. And because it also supports CEC (Consumer Electronics Control), it’s also able to turn on and off with your TV, so once it’s set up, all you need to worry about is getting lost in its room-filling sound. 

While the Ren doesn’t support Dolby Atmos—it has a 1-inch tweeter and 5.25-inch cone, and both are forward facing—I found that I genuinely didn’t miss it. I made the change from a large-and-in-charge $1,000 Dolby Atmos soundbar from another brand, complete with all the bells and whistles that go with such a high price. I was shocked to realize that the Ren immediately sounded better, filling my living room with its rich and detailed sound at lower volume levels than my “top of the line” Atmos soundbar ever could. It’s hard to miss positional audio when the Ren—which still supports normal Dolby Surround Sound – so easily positions you squarely in center stage. 

Of course, a soundbar replacement isn’t all it is. The Kanto Ren supports all of the usual audio input sources you would expect, including RCA, Optical TOSLINK, Bluetooth 5.3, 3.5mm aux-in, and even USB Type-C for quick connections with smart devices. Swapping between these inputs is as easy as pressing the volume button, and a color-coded LED indicates which source the speakers are currently set to receive. 

The sound is, simply put, outstanding. The speakers effortlessly reproduce deep lows while the silk-dome tweeters resolve high-frequency details with ease. I own a home, but I appreciate that these speakers sound great even at nighttime listening levels; you don’t need to wake the neighbors to enjoy them to their fullest (though they do sound great when cranked up). 

Nothing is perfect, of course, and I did run into occasional issues with the Ren and my TV getting out of sync, which resulted in no sound being produced. This seemed to be related to powering down the TV while it was muted, but I wasn’t able to reproduce it, and a simple power cycle always resolved it. 

Overall, the Kanto Ren is a fantastic pair of speakers, whether you’re enjoying a movie, playing a game, or getting lost in your favorite song.

Things to consider when buying powered bookshelf speakers

Buying powered bookshelf speakers is about matching performance to your space and your habits. Unlike passive models, you can’t swap out the amp later, so it’s important to get the right mix of size, power, and features from the start. Think about what you’ll connect, where your speakers will live, and how you’ll listen; those answers will guide the rest.

What features should I consider?

The features you should consider come down to how you’ll use the speakers. If a turntable is part of your setup, check whether the speakers have a phono input or if you’ll need an external preamp. If you want powered speakers for your TV, HDMI ARC makes connecting painless. For wireless streaming, Bluetooth support is pretty standard in this class, while some higher-end models offer Wi-Fi, allowing higher-res listening. If you’re a tone tinkerer—or dealing with tricky placement in a room—look for speakers with onboard EQ or a companion app that lets you adjust sound. And if you need studio-level versatility, pro connections like balanced XLR or TRS are worth seeking out.

What size speakers should I get?

The size of speakers you should get is mostly determined by your space. Bigger speakers with 5- or 6-inch drivers deliver more powerful sound with deeper bass, making them great for larger rooms. But bigger isn’t always better—oversized speakers can overwhelm a small space and sound boomy if you can’t turn them up to their ideal volume. More compact 3- or 4-inch drivers are better for desktops or apartments, though you may want to add a subwoofer if you’re missing that visceral low-end impact.

Do I need a subwoofer? 

Whether you need a subwoofer depends on what you listen to. Many powered bookshelf speakers sound full on their own, especially for casual listening. But if you want to feel explosions in movies, big EDM bass drops, or just deeper lows overall, a subwoofer will give you that extra punch.

FAQs

Q: What are powered speakers?

Powered speakers are speakers with a built-in amplifier, which means they don’t need a separate receiver to work. You just plug them into power, connect your source, and you’re good to go. Because the amp and drivers are tuned together, powered speakers are often easier to set up and sound balanced right out of the box.

Q: What are bookshelf speakers used for?

Bookshelf speakers are used for a range of listening setups. They’re compact enough to sit on a desk, shelf, or stand, but powerful enough to fill a typical living room with sound. People use bookshelf speakers for hi-fi listening, home theater front channels, content production setups, desktop gaming rigs, and even as secondary speakers in multi-room setups.

Q: Are powered bookshelf speakers good for music production?

Powered bookshelf speakers can be good for music production, depending on your needs. Some models are voiced more like hi-fi speakers, while others borrow studio monitor design for a flatter, more detailed sound. If you’re a content creator or bedroom producer, powered bookshelves can give you an accurate playback reference to mix on, while still doubling as enjoyable hi-fi speakers for casual listening.

A final word on the best powered bookshelf speakers

Powered bookshelf speakers are all about balance: big sound without the big stack of gear. Whether you’re chasing studio-style accuracy, hi-fi warmth, or an all-in-one compact setup for everyday listening, the models here prove you can find great sound that fits your space and your budget.
