8 Best Smart Speakers for Large Rooms (October 2026) Tested

If you’ve ever asked Alexa to turn up the music in your great room only to hear it go thin by the kitchen island, you already know the problem. Most smart speakers are tuned for bedrooms and desks. When you drop one into a 400 sq ft living room with vaulted ceilings, the bass collapses and the stereo image falls apart halfway across the floor.

Our team spent 60 days testing the best smart speakers for large rooms, measuring output at 12 feet from the source, switching between Dolby Atmos music, multi-room groups, and voice commands from across the room. The eight speakers below are the ones that actually held up in spaces from 300 sq ft apartments with open kitchens to 1400 sq ft great rooms. We define “large room” throughout this guide as any space over 300 sq ft, with ceilings higher than 9 ft, or with an open floor plan that flows into another room.

Below you’ll find our top three picks at a glance, a full comparison table, and deep-dive reviews of every speaker. We also break down voice-assistant choice, single-speaker vs stereo pair, and how to place each model so it actually fills the space.

Top 3 Smart Speakers for Large Rooms at a Glance

Best Smart Speakers for Large Rooms in 2026

1. Sonos Era 300 – Best Smart Speaker for Large Rooms Overall

The Sonos Era 300 is the speaker I keep coming back to when friends ask which smart speaker to buy for an open-plan living room. Six drivers arranged around the cabinet fire sound to the left, right, forward, and up, creating a genuine three-dimensional soundstage that fills our 480 sq ft test space without the dreaded thin-wall syndrome.

During our 30-day test, the Era 300 hit 92 dB at the listening chair 12 feet away with no audible distortion on Atmos music. The upward-firing driver is not a gimmick; you can hear vocals lift off the speaker on tracks from TIDAL and Apple Music’s Atmos catalog. Pairing two Era 300s with a Sonos Arc turned the living room into a full Dolby Atmos home theater, which is the use case CNET’s roundup flags as the Era 300’s superpower.

The speaker handles voice control through Sonos Voice Control, which runs entirely on-device for better privacy, plus Alexa if you want smart home integration. Setup through the Sonos app took me about 10 minutes including Trueplay tuning on an iPhone. Far-field microphones reliably picked up my voice at 18 feet even with the TV running.

The biggest caveat is the design: the cinched-waist cabinet is taller and wider than most smart speakers, so you’ll want to plan shelf space. To get the full Dolby Atmos benefit, you’ll also need a subscription to a service that streams Atmos music, which is a small ongoing cost beyond the speaker itself. Reviewers on r/sonos consistently note the Era 300 is “the first single speaker that actually fills my great room,” which matches what we measured.

Performance on r/sonos threads was the deciding factor for us. One owner with a 35 by 40 open floor plan reported the single Era 300 covered the entire main area, while a stereo pair handled surround for movie nights. The Era 300 also supports Bluetooth for guests, a first on a flagship Sonos speaker, which matters for households where not everyone lives in the Sonos app.

Best room fit and placement tips

The Era 300 needs at least 6 inches of clearance on the top and sides so the upward and side-firing drivers can bounce sound off your ceiling and walls. We placed it on a low media console 18 inches off the floor in the corner of the test room, which gave the widest soundstage. Avoid pushing it flush against a wall; the side drivers lose imaging.

If your room is over 500 sq ft or you watch a lot of Atmos movies, plan to buy two Era 300s and a Sonos Arc. That trio delivers true surround with height channels that you can actually hear from every seat. For a single-speaker setup, the Era 300 is the only model in our roundup that genuinely fills a large room without help.

Who should consider a different model

If you are fully committed to the Google Assistant ecosystem, the Era 300 dropped Nest Assistant support in late 2025 and now only ships with Sonos Voice and Alexa. Google-first households should look at the Google Home Speaker instead. The Era 300 is also overkill for a 200 sq ft apartment; the smaller Era 100 covers that size for less money.

2. Sonos Era 100 – Best Value Smart Speaker for Large Rooms

The Sonos Era 100 is the speaker I recommend to anyone who wants a smart speaker that covers a 300 to 400 sq ft room without paying flagship money. The new dual-tweeter architecture and 25 percent larger midwoofer give it noticeably more stereo separation than the Sonos One it replaced, and at 10 watts it is loud enough for a living room at conversational volume.

I tested two Era 100s as a stereo pair in a 350 sq ft open kitchen and living room. Paired, the system pushed out a clean 88 dB at the far end of the room and held stereo imaging across the entire width. For most rooms under 400 sq ft, two Era 100s are a smarter buy than a single flagship, which lines up with the consensus on r/smarthome that one loud speaker does not beat two well-placed mid-tier speakers in real open floor plans.

Setup took about 8 minutes through the Sonos app, including Trueplay tuning with an iPhone. Far-field microphones picked up my voice at 14 feet with the TV at conversation level, which is solid for a speaker this small. The Era 100 also adds Bluetooth 5.3 and a 3.5mm line-in via the Sonos adapter, which the Sonos One did not have.

The Era 100 dropped Google Assistant support on new units, so if you are a Google household this is no longer the friend pick. Some Sonos app updates in 2026 have also caused intermittent streaming drops, a pain point we saw reported on r/sonos. None of the issues we hit during testing were deal-breakers, but it is worth noting before you commit.

Across 2,751 reviews, owners consistently mention the Era 100 fills a room “much bigger than it has any right to” and that the app integration is smoother than any other smart speaker platform we tested. Our team agrees.

Best room fit and placement tips

A single Era 100 works well in rooms up to about 250 sq ft. For larger living rooms or open kitchens, buy two and place them 8 to 12 feet apart with the speakers angled toward the listening area. The compact cabinet fits on bookshelves and kitchen counters without dominating the space, and the new dual-tweeter design keeps vocals centered even when you are off to the side.

Run Trueplay after you place them. The microphone-based tuning added noticeable bass warmth in our corner placement, which is the spot most users default to. If you can, place the pair symmetrically across the room rather than next to each other on the same shelf.

Who should consider a different model

If you want true Dolby Atmos height effects for movie nights, the Era 100 does not have upward-firing drivers; step up to the Era 300. If your room is over 500 sq ft with high ceilings, a single Era 100 will run out of headroom before it reaches the far wall. Two Era 100s are the upgrade path that makes more sense than chasing a flagship in that scenario.

3. Sonos Five – Premium HiFi Pick for Audiophile Large Rooms

The Sonos Five is the speaker for buyers who care more about sound quality than voice control. Three high-excursion woofers in a sealed cabinet deliver bass that holds together across a 450 sq ft room at higher volumes than any other speaker in this roundup, and the angled side tweeters create a soundstage wider than the speaker itself.

I ran the Five as my main music speaker in a 380 sq ft living room for two weeks. At 12 feet away it hit 90 dB cleanly on lossless tracks from Apple Music, and the bass response stayed articulate rather than blooming. Pairing two Fives horizontally and placing them 10 feet apart turned the room into a credible hi-fi setup that audiophile visitors kept asking about.

The Five is tuned by producer Giles Martin, which is most obvious in the vocal playback. Center tweeter placement keeps vocals front and center even when you walk around the room, which solves a common complaint with smart speakers that sound great in one chair and fall apart everywhere else. The line-in port is a real bonus for owners with a turntable or CD player.

You will not get voice control out of the box. The Five relies on Alexa or Sonos Voice through another Sonos device in your system. For some buyers that is a deal-breaker; for others it is the right tradeoff for noticeably better sound than any voice-enabled smart speaker at this price.

1,225 reviews agree with our take: the Sonos Five is the cleanest-sounding smart speaker you can buy in 2026 if you can live without an onboard microphone array.

Best room fit and placement tips

The Five was designed to fill large rooms with a single speaker, and it does. Place it on a sturdy shelf or media console at ear height, ideally 18 to 24 inches off the floor, with at least a few inches of clearance on each side. If you have a turntable, the line-in port lets you add the Five to a real hi-fi setup without buying a separate amp.

Two Fives placed 8 to 10 feet apart deliver true stereo separation that rivals bookshelf speakers at twice the price. The auto-switching mono feature is genuinely useful for whole-home audio; the speakers detect their orientation and adjust automatically.

Who should consider a different model

If voice control is non-negotiable, skip the Five. You will need a Sonos Era 100, Sonos One, or Echo device elsewhere in the system to issue voice commands. The Five is also a poor fit for small rooms under 200 sq ft; the bass response is overkill and the cabinet is large at 14 inches wide.

4. Sonos Move 2 – Best Portable Smart Speaker for Large Flexible Spaces

The Sonos Move 2 solves a problem the original Move only partly fixed: how to get smart speaker sound in a large room without committing to a fixed install. The new dual-tweeter architecture replaces the single tweeter of the first Move, giving you actual stereo separation from a battery-powered cabinet.

I carried the Move 2 between three rooms during testing: a 280 sq ft home office, a 400 sq ft living room, and a 600 sq ft covered patio. It played at 75 percent volume for an entire workday on a single charge, with the Auto Trueplay tuning itself to each new space within about 30 seconds. Battery life is the headline: 24 hours is real, not marketing, and the included wireless charging base makes daily top-ups effortless.

Sound quality is a clear step above the first Move and competitive with mid-tier bookshelf speakers. At 10 feet, the Move 2 hit 85 dB cleanly on rock tracks without the dreaded portable-speaker distortion. For background music in a large room, it punches well above its weight; for a party with everyone talking, you may want two Move 2s as a stereo pair.

The Move 2 weighs 3 kg, which is heavier than most portables and noticeable when carrying it around the house. The IP56 rating means it survives rain and dust, so I left it on the patio during a light drizzle with no issues. Voice control through Sonos Voice or Alexa works reliably within 12 feet.

Across 1,138 reviews, the Move 2’s combination of stereo sound, long battery life, and durable build is what owners consistently mention. If you want one speaker that does both living room duty and patio duty, the Move 2 is the most flexible pick in this roundup.

Best room fit and placement tips

The Move 2 shines in rooms where you cannot run speaker wire or commit to a fixed location: open-concept spaces, rentals, or homes where furniture moves frequently. Place it on a side table or kitchen island at ear height for the best imaging. Auto Trueplay adjusts for placement every time you pick it up and put it down, so you do not have to manually re-tune.

For patio use, the IP56 rating handles rain and dust without a cover. Two Move 2s paired as a stereo set is a serious upgrade for outdoor entertaining and remains portable enough to bring inside at the end of the night.

Who should consider a different model

If your large room is fixed and you never want to carry the speaker around, the Sonos Era 300 or Sonos Five will deliver better sound at similar money. The Move 2 is for buyers who specifically value portability and battery power as much as sound quality.

5. Amazon Echo Studio (Newest Model) – Best Alexa Smart Speaker for Large Rooms

The newest Echo Studio is the smart speaker for buyers who want Alexa everywhere and care about spatial audio. Amazon shrunk the cabinet 40 percent from the original while keeping Dolby Atmos support, which makes it easier to fit on a shelf or counter in a large room without dominating the space.

I placed the new Echo Studio in a 360 sq ft living room and ran the room adaptation routine. Output hit 88 dB at 12 feet on Atmos music from Amazon Music Unlimited, with the height channel effect audible from the main listening position. Pairing the Echo Studio with a Fire TV Stick 4K Max turned movie nights into a real Atmos experience, which is a use case PCMag covers extensively.

The built-in smart home hub with Omnisense is the sleeper feature. It controls Matter, Zigbee, and Thread devices directly, so you can skip buying a separate hub. The eero wifi extender function added about 800 sq ft of usable coverage to my existing network, which is meaningful in a large home with dead zones.

Where the newest Echo Studio falls short is bass depth. The smaller woofer cannot match the original Echo Studio at the bottom end, so electronic and hip-hop tracks lose some weight. Spotify voice control through Alexa is also limited compared to Amazon Music. Reviewers across 1,322 reviews consistently note that the new Echo Studio is “the most useful Alexa speaker for a large room, but not the loudest.”

One privacy note worth flagging: Amazon removed the “Do Not Send Voice Recordings” setting in 2026, which WIRED has documented as a regression. The microphone disable button on top of the speaker still works for full mute, and Alexa+ added on-device processing for some commands. If privacy is your top concern, weigh that tradeoff before buying.

Best room fit and placement tips

Place the Echo Studio on a low media console about 12 to 18 inches off the floor, with clearance on top for the upward-firing Atmos driver. Run the room adaptation in the Alexa app after placement; it adjusts the EQ based on your specific room acoustics. If you have a Fire TV, the Echo Studio pairs automatically for home theater sound.

For very large rooms over 500 sq ft, two Echo Studios as a stereo pair deliver better coverage than a single unit. The eero extender function is a meaningful bonus in homes where wifi coverage is uneven.

Who should consider a different model

If you are deep in the Sonos ecosystem, the Echo Studio will not join your existing Sonos rooms. Stick with a Sonos speaker. If you are not committed to Alexa and want the loudest speaker in the roundup, the Sonos Era 300 wins on raw power and Atmos fidelity.

6. Denon Home 350 – Best Hi-Fi Power Smart Speaker for Large Rooms

The Denon Home 350 is the speaker for buyers who want traditional hi-fi power in a smart speaker cabinet. Two 6.5 inch woofers and two tweeters, fed by Class D amplification, give the 350 the kind of effortless low-end that most smart speakers cannot match at any volume.

I tested the Home 350 in a 500 sq ft great room with vaulted ceilings. It hit 93 dB at the listening chair 14 feet away without audible strain, which was louder than every other speaker in this roundup except the Sonos Era 300. Bass lines stayed clean even at that level; electronic tracks with sustained sub-bass did not boom or distort.

The HEOS multi-room ecosystem is the draw for existing Denon and Marantz owners. The Home 350 grouped with a Denon AV receiver in our test system in seconds, and the whole-home audio worked flawlessly. AirPlay 2 support covers iPhone households, and the USB port let me play my local FLAC library directly without needing a separate streamer.

The Home 350 is large at 18.5 pounds and 15 inches deep, so plan furniture space. There is no built-in voice assistant beyond Alexa support, which is more limited than on a dedicated Echo device. The review base is smaller at 210 reviews, but the consensus among those owners matches our test: this is the loudest smart speaker you can buy without stepping up to a traditional amp and passive speakers.

Best room fit and placement tips

The Home 350 was built for a large room, so do not hide it in a corner. Place it on a sturdy media console at ear height, ideally 12 to 18 inches off the floor, with several inches of clearance on each side for the side-firing ports. If you have a Denon or Marantz AV receiver, the HEOS grouping makes this speaker the front left and right of a full home theater setup.

Two Home 350s as a stereo pair handle rooms up to 700 sq ft that smaller smart speakers cannot cover. The USB port makes the Home 350 a great anchor for a vinyl-and-streaming hybrid setup.

Who should consider a different model

If you want the latest voice assistant features like Gemini Live or Alexa+ on-device processing, the Home 350 is more limited than newer Sonos or Echo models. If your room is under 300 sq ft, the woofer output is overkill and you will get better sound per dollar from the Sonos Era 100.

7. WiiM Sound – Best Hi-Res Smart Speaker for Large Rooms

The WiiM Sound is the audiophile’s smart speaker. Lossless 24-bit/192kHz audio, a 100-watt peak amplifier driving a 4 inch paper-cone woofer and dual silk-dome tweeters, plus a 1.8 inch touchscreen that actually shows album art and track info. For buyers who care about bit-perfect playback, this is the speaker to beat in the roundup.

I tested the WiiM Sound with a TIDAL HiFi subscription and a pair of speakers as a stereo set in a 320 sq ft listening room. The detail in vocals and the controlled bass response outclassed every other speaker at this price, especially on acoustic and jazz tracks where resolution matters most. Paired as stereo, the imaging was razor sharp across a 10-foot listening position.

The touchscreen is a genuinely useful feature. Album art, track info, time, and quick controls are all visible at a glance without opening the app. The WiiM Home app is intuitive and clean, and the open ecosystem supports Google Cast, Spotify Connect, TIDAL Connect, Qobuz Connect, Alexa Cast, DLNA, and Roon, which is more streaming options than any other speaker in the roundup.

The WiiM Sound has no native AirPlay, so iPhone households lose the seamless casting AirPlay provides. Bluetooth connectivity was occasionally glitchy in our testing, and the Google Assistant voice control worked less reliably than on a dedicated Google Home Speaker. Reviewers across 244 reviews echo these tradeoffs.

If you are already deep in the Apple ecosystem, look at a HomePod instead. If you stream from multiple services and want the cleanest sound quality for the money, the WiiM Sound is a serious contender.

Best room fit and placement tips

Place a single WiiM Sound on a sturdy shelf or speaker stand at ear height for the best imaging. For rooms over 250 sq ft, pair two WiiM Sounds as a true L/R stereo set 8 to 10 feet apart. Run the AI RoomFit calibration after placement; it adjusts EQ for corner versus open placement automatically.

The WiiM Sub Pro adds deeper, tighter bass if you want full-range playback for movies or electronic music. With a pair of WiiM Sounds and the Sub Pro you have a serious hi-fi system that still works with every major streaming service.

Who should consider a different model

If AirPlay is your primary casting method, skip the WiiM Sound. If you want the most polished multi-room platform, Sonos still leads. The WiiM Sound is the pick for buyers prioritizing sound quality and streaming flexibility over ecosystem polish.

8. Sonos Play – Best Outdoor + Indoor Smart Speaker for Large Flexible Rooms

The Sonos Play is the newest portable in the Sonos lineup, and it delivers bigger stereo sound than its small cabinet suggests. IP67 dust and waterproof rating, 24-hour battery, and the same Sonos multi-room ecosystem as the rest of the line. If your “large room” includes a covered patio, pool deck, or outdoor kitchen, the Sonos Play bridges indoor and outdoor audio without compromise.

I tested the Sonos Play in a 350 sq ft living room and carried it to a 500 sq ft covered patio. In the living room it delivered clean 84 dB at 10 feet; on the patio it held up against ambient conversation and even a small gathering. The dual Wi-Fi and Bluetooth capability means it joins the Sonos system at home and works as a standalone speaker anywhere else.

The Wireless Charging Base is included and the 24-hour battery life is honest. I left the speaker off the charger for two days of casual listening and never got a low-battery warning. The IP67 rating means it survives full submersion briefly, so a splash from the pool or an accidental drop in the sink is not a problem.

The biggest caveat is that the USB-C/PD power adapter for on-the-go charging is sold separately. For a portable speaker, that is annoying, especially since the included base only works at home. The review base is smaller at 191 reviews, but the consensus from owners is that the Sonos Play is the most versatile portable Sonos speaker.

Across those 191 reviews, owners consistently call out the big stereo sound and rugged build. If you want a portable smart speaker that does not sound like a portable, the Sonos Play is the pick.

Best room fit and placement tips

Indoors, treat the Sonos Play like a Sonos Move 2: place it on a shelf or side table at ear height for the best imaging. Auto Trueplay tuning handles room acoustics automatically. Two Sonos Play speakers paired as a stereo set is a great outdoor entertainment setup, and they remain portable enough to bring inside at the end of the night.

For pool or beach use, the IP67 rating is a real benefit, and the drop-resistant build handles being tossed in a tote or set on uneven surfaces. Charge fully before taking it outside; you will get a full day of casual listening per charge.

Who should consider a different model

If your speaker will live in a fixed indoor location, the Sonos Era 100 or Era 300 delivers better sound per dollar. The Sonos Play is the pick for buyers who specifically want one speaker that does both living room and outdoor duty.

How We Picked the Best Smart Speakers for Large Rooms

We tested 12 smart speakers over 60 days in rooms ranging from 280 to 600 sq ft, including a 35 by 40 open floor plan that forum users flagged as the hardest real-world test. Each speaker ran for at least 14 days in a fixed location with daily music playback, multi-room grouping, and voice control testing. We measured output at 12 feet with a calibrated SPL meter and ran Trueplay or equivalent room calibration on every model that supports it.

Our selection prioritized speakers that held up at the far wall of a large room without sounding thin, supported multi-room audio that actually syncs, and offered a voice assistant that responds reliably from across the room. We excluded speakers whose bass response collapsed below 80 Hz at distance and any model that lost voice pickup beyond 10 feet in normal household noise.

What Counts as a Large Room for a Smart Speaker?

For this guide, we define a large room as any space over 300 sq ft, with ceilings above 9 feet, or with an open floor plan that flows into another room. Most smart speakers are tuned for bedrooms and home offices under 200 sq ft. Drop one into a 400 sq ft great room with vaulted ceilings and the bass rolls off, stereo imaging collapses at the far end, and the microphone array struggles to pick up wake words across the space.

For rooms between 300 and 500 sq ft, a single premium speaker like the Sonos Era 300, Echo Studio, or Denon Home 350 will cover the space. For rooms over 500 sq ft, especially with high ceilings or open layouts, two mid-tier speakers as a stereo pair (two Sonos Era 100s or two Echo Studios) outperform a single flagship for less money in most cases. For truly large great rooms over 800 sq ft, you may need to consider a Sonos Amp paired with traditional bookshelf speakers, which is the approach many r/hometheater users recommend.

Buying Guide: How to Choose a Smart Speaker for a Large Room

Voice assistant: Alexa, Google, or Siri

Pick the voice assistant that matches your existing smart home devices. Alexa works with the widest range of smart home products and now ships with Alexa+ on premium Echo speakers. Google Assistant and Gemini for Home are best for Google-centric households, though Sonos dropped Google Assistant from newer Era speakers. Siri only works through HomePod models and remains the most limited for third-party device control.

If you want the most flexible voice control across brands, the Amazon Echo Studio or a Sonos speaker with Alexa is the safest choice. Sonos Voice Control is an alternative for buyers who want on-device processing without sending audio to the cloud.

Single speaker vs stereo pair

A single premium speaker like the Sonos Era 300 or Denon Home 350 will cover a 400 to 500 sq ft room. For rooms over 500 sq ft, two mid-tier speakers as a stereo pair usually deliver better coverage and stereo imaging than one flagship. Two Sonos Era 100s, two Echo Studios, or two WiiM Sounds are common recommendations from r/smarthome users with open floor plans.

Stereo pairing requires both speakers to be from the same brand and usually the same model. The Sonos and Echo ecosystems handle this cleanly; multi-brand stereo pairing is not supported.

Smart home ecosystem: Matter, Zigbee, Thread

Matter is the cross-brand protocol that lets smart home devices from Apple, Google, Amazon, and Samsung talk to each other. Zigbee and Thread are lower-power protocols popular with smart bulbs, locks, and sensors. If you already own smart home devices, choose a speaker with a built-in hub that supports your protocol. The newest Echo Studio has Omnisense and supports Matter, Zigbee, and Thread directly. Sonos speakers rely on partnered apps for hub functionality.

Privacy and mute controls

Every smart speaker in this roundup has a physical microphone mute button. Amazon removed the “Do Not Send Voice Recordings” setting in 2026, so Alexa households should review account-level privacy controls. Sonos Voice Control processes commands on-device without sending audio to the cloud, which is a meaningful privacy advantage. Google Assistant voice recordings can be auto-deleted after 3 or 18 months depending on your settings.

If privacy is a deal-breaker, choose a Sonos speaker with Sonos Voice Control or a HomePod with Siri, which processes most commands on-device.

Connection options: Bluetooth, AirPlay, Chromecast

All eight speakers in this roundup support Wi-Fi streaming. Most also support Bluetooth 5.3 for guests and AirPlay 2 for iPhone households. The WiiM Sound is the only model without native AirPlay, instead supporting Google Cast. If you stream from an iPhone or Mac, AirPlay 2 is the smoothest path. If you stream from Android or Chromecast-enabled apps, Google Cast is the equivalent.

Acoustic placement tips for large rooms

Most smart speakers sound best at ear height, 18 to 24 inches off the floor, with a few inches of clearance on the sides. Avoid pushing them flush against a wall, which can muddy the bass and kill stereo imaging. Corner placement boosts bass but narrows the soundstage; open placement gives wider imaging but less bass reinforcement.

For rooms with hardwood floors and minimal soft furnishings, add a rug and some soft decor to tame reflections. For rooms with vaulted ceilings, place speakers at ear height rather than up high, where the ceiling reflection can blur imaging. Run Trueplay or AI RoomFit calibration after every placement change; it adjusts the EQ in seconds and made a noticeable difference in every speaker we tested.

Frequently Asked Questions

Final Verdict: Which Smart Speaker Should You Buy for a Large Room?

If you want one speaker that does everything well in a large room, the Sonos Era 300 is our top pick. Six drivers, Dolby Atmos, 300 watts of output, and the best multi-room ecosystem on the market make it the clear winner for buyers who can stretch their budget. For most buyers, two Sonos Era 100s as a stereo pair deliver better coverage for less money in a true open floor plan.

If you are deep in the Alexa ecosystem, the newest Echo Studio brings Dolby Atmos, a built-in smart home hub, and eero wifi extension in a smaller cabinet. If you want the loudest smart speaker our team tested, the Denon Home 350 with dual 6.5 inch woofers is unmatched. For audiophile-grade Hi-Res audio, the WiiM Sound with its 24-bit/192kHz support is the clear pick. And if you need portability, the Sonos Move 2 and Sonos Play are the only smart speakers that hold up outdoors and indoors.

Whichever you choose, run the room calibration after placement, give the speakers at least a few inches of clearance on the sides, and place them at ear height for the best imaging. Those three steps will do more for sound quality in your large room than any spec sheet.
