Best Soundbars with Integrated Voice Assistant

TL;DR: The Bose Smart Ultra packs nine built‑in speakers in a 5.0.2 layout, AI Dialogue Mode and ADAPTiQ calibration for crisp, immersive sound, but its bright tonality and modest bass may need a subwoofer for larger rooms.

The standout spec is the nine‑speaker driver array delivering a 5.0.2 channel layout; the bar measures 107 mm deep, 58 mm high and 1045 mm wide, and weighs 12.68 lb. AI Dialogue Mode automatically lifts vocal clarity, while ADAPTiQ uses built‑in mics to tailor the sound to your room.

Compared with the other five soundbars in this roundup, the Ultra is heavier than the Denon Home 550 (7.3 lb) and the Samsung HW‑S61D (≈5.9 lb) but lighter than the Polk Audio Signa S3 (≈19 lb). It is wider than the Bose Smart Dolby Atmos (≈694 mm) and the Samsung model (≈670 mm), yet its depth (107 mm) is only a millimeter deeper than the Samsung bar and matches the Bowers & Wilkins Panorama 3’s depth of 107 mm. In driver count, it matches the nine elements listed for the Denon Home 550, while the Bowers & Wilkins unit lists individual driver sizes but not a total count.

Professional reviewers highlight the AI Dialogue auto‑adjustment as a major plus, noting that it makes TV dialogue stand out without manual tweaking. Users echo this, praising the ultra‑crisp vocals and the sense of spaciousness from the nine speakers. The downside that appears repeatedly is a bright, treble‑heavy default profile that can fatigue ears, and a lack of deep bass unless you add the optional subwoofer. Height channel performance is also described as weaker without satellite speakers, which limits full‑room immersion in larger spaces.

Beyond the audio, the Ultra supports AirPlay 2, Chromecast, Bluetooth, Wi‑Fi and voice control via Alexa or Google Assistant. It offers low audio latency and a video passthrough capable of 4K 120 Hz, 10‑bit, 4K 4:4:4, making it a solid match for high‑refresh‑rate gaming or streaming.

Best for: Those prioritizing premium sound quality, integrated voice assistants and are willing to invest in a high‑end standalone Atmos bar.

Avoid if: You have a tight budget, need deep bass out of the box, or require full‑room height immersion without extra speakers.

TL;DR: At $329, the Polk Signa S3 delivers a low‑profile 2.1‑channel soundbar with built‑in Chromecast, Google Assistant, and a wireless subwoofer, earning a 4.4‑star rating from nearly 25 k reviewers.

The Signa S3 sits just 2.15 in tall and 3.22 in deep, making it among the slimmest bars available. The soundbar itself weighs only 3.96 lbs, while the wireless subwoofer adds 11.46 lbs, bringing the total system to 15 lbs. Integrated Google Assistant, built‑in Chromecast, Bluetooth, HDMI ARC, optical and 3.5 mm AUX inputs give you every major connection method without clutter.

Compared with the Samsung HW‑S61D, Polk’s 3.22 in depth is shallower than Samsung’s 105 mm depth, and its soundbar is lighter than the Bose Smart Dolby Atmos unit that weighs 6.909 lb. The total system weight of 15 lb exceeds the Denon Home 550’s 7.3 lb and the Bose Smart Ultra’s 12.68 lb, but it still fits comfortably on a TV stand. Its dimensions also fall below those of the Bowers & Wilkins Panorama 3, whose depth and height are listed in millimetres, resulting in a taller profile.

Users consistently praise the easy plug‑and‑play setup and the VoiceAdjust dialogue boost, which offers three levels of speech enhancement. Professional reviewers note that Dolby Digital decoding and DTS virtual surround deliver clear TV dialogue and a solid front soundstage, even though the system remains limited to 2.1 channels. The wireless subwoofer’s 13.4 in height can be a concern in tight spaces, and manufacturers haven't listed power‑output specifications, limiting direct loudness comparison.

Best for: Budget-conscious buyers seeking a reliable entry-level option

Avoid if: You have limited desk space or need portability

TL;DR: The Samsung HW‑S61D delivers a compact 5.0‑channel soundbar with built‑in Alexa, 7 speakers, and virtual Dolby Atmos, all for $278, making it a solid entry‑level voice‑assistant option.

The standout feature is its all‑in‑one layout: seven drivers—including four woofers, three tweeters, and a built‑in center speaker—feed a 5.0‑channel system while side‑firing speakers add width. Virtual Dolby Atmos and DTS Virtual:X aim to create height effects without separate up‑firing modules, and the bar includes a built‑in Alexa voice assistant for hands‑free control.

At 105 mm deep, 62 mm tall and 670 mm wide, the HW‑S61D sits between the ultra‑slim Bose Smart Dolby Atmos (104 mm × 56 mm × 694 mm) and the deeper Denon Home 550 (119.9 mm × 74.9 mm × 659.7 mm). Weighing 2700 g, it’s lighter than the Polk Soundbar + sub’s total system weight of 15 lb, yet comparable to the Bose Smart Dolby Atmos’s 6.9 lb chassis. Unlike several peers, Samsung lists built‑in Alexa and Google compatibility, while competitors such as the Polk Signa S3 and Denon Home 550 do not specify integrated voice assistants.

Reviewers appreciate the straightforward setup—thanks to the included remote and wall‑mount bracket—and the clear dialogue boost the dedicated center speaker provides. The bar’s Energy Star certification and 31 W operating power keep electricity use modest, with standby dropping to just 0.5 W. However, users note that the absence of a separate subwoofer can leave low‑frequency moments feeling thin, and the lack of wireless rear‑speaker modules prevents true surround immersion.

Best for: Entry-level buyers or those on a tight budget

Avoid if: You want the best value‑per‑dollar in its price range

TL;DR: The Bose Smart Dolby Atmos soundbar packs 5‑channel Dolby Atmos, Alexa voice control and a compact 56 mm height into a 6.909‑lb unit for $419.00, making it a strong mid‑range choice for small‑to‑medium rooms.

At the core of the bar is a five‑speaker array that includes two upward‑firing drivers and a center tweeter, delivering 5‑channel Dolby Atmos and Dolby TrueHD. The unit measures 104 mm deep, 56 mm tall and 694 mm wide, and weighs 6.909 pounds, so it slides under most TVs without blocking the screen. Bluetooth 5.0 reaches up to 30 ft, and built‑in Alexa lets you control playback hands‑free.

Compared with the other five entries, the Bose Smart Dolby Atmos sits in the middle of the price band – it’s pricier than the Polk Audio Signa S3 and Samsung HW‑S61D, yet noticeably cheaper than the Denon Home 550 and the higher‑end Bose Smart Ultra. In weight, it’s heavier than Samsung’s 2700 g model but lighter than the Bose Ultra’s 12.68 lb chassis. Feature‑wise it offers Apple AirPlay 2, HDMI ARC and Wi‑Fi, matching the connectivity of its peers while adding AI Dialogue Mode and QuietPort technology.

Reviewers consistently note the bar’s slim 56 mm profile (about 2.21 in) as a major convenience for apartments or bedroom setups. Professionals highlight the precise placement of the five speakers and the upward‑firing drivers as delivering convincing overhead effects in a compact package. The trade‑off is the smaller speaker count – several critics point out that nine‑driver premium models create more impact – and the lack of an ADAPTiQ automatic room‑calibration system, which could benefit users seeking fine‑tuned acoustics.

Best for: Value-conscious buyers seeking quality at $419.00

Avoid if: You need a large open‑concept room or want automatic room‑calibration features

TL;DR: The Denon Home 550 packs a 4.0‑channel virtual surround system, Dolby Atmos/DTS:X support and Alexa/Siri voice control into a compact 25.95‑in‑wide bar that sits under most 55‑inch TVs, but it carries a premium $679.99 price tag.

What really sets the Home 550 apart is its six‑driver layout: two 0.75‑in tweeters and four 2.1875‑in full‑range drivers, complemented by three 2 × 3.5‑in passive radiators. This configuration fuels a 4.0‑channel virtual surround engine that can decode Dolby Atmos and DTS:X without a separate subwoofer. The bar measures 25.95 in wide, 2.95 in high and 4.72 in deep, and it weighs 7.3 lb, making it a solid‑looking yet manageable addition to a living‑room setup.

Compared with the five other soundbars in this roundup, the Denon is a bit heavier than the Bose Smart Dolby Atmos at 6.909 lb, but far lighter than the Bose Smart Ultra (12.68 lb) and the Bowers & Wilkins Panorama 3 (about 14.33 lb). It also undercuts the Polk Audio Signa S3, which tips the scales at roughly 18.96 lb. In width, the Home 550’s 25.95 in footprint is comparable to the Bose Dolby Atmos’s 694 mm chassis and slimmer than the Bose Ultra’s 1045 mm span. Its depth of 4.72 in sits close to Samsung’s 105 mm (about 4.13 in) design, while the Samsung unit weighs 2700 g, making the Denon a bit heftier but still easy to wall‑mount.

Users consistently praise the bar for its straightforward HDMI eARC hookup and the space‑saving design that fits neatly beneath a TV. Reviewers note the virtual surround creates a surprisingly wide soundstage for a single‑box solution, and the built‑in HEOS platform lets you stream from Spotify, Amazon Music HD, TIDAL and more. Professional reviewers highlight the balanced 3‑D audio that the six compact drivers deliver, while consumer comments point out that the lack of a dedicated subwoofer can leave deep bass a little thin in larger rooms. The manufacturer doesn’t list RMS wattage, so power output isn’t disclosed, but the inclusion of Alexa and Siri voice assistants adds hands‑free control to the mix.

Best for: Most users seeking a balanced, mainstream option

Avoid if: You're shopping on a tight budget — it's priced at $679.99

TL;DR: The Bowers & Wilkins Panorama 3 delivers premium 3.1.2‑channel Dolby Atmos sound with 13 drivers, Alexa integration and 500 sq ft coverage, but its $999 price and bulky footprint may deter budget‑focused buyers.

The Panorama 3 stands out with a 13‑driver architecture, including two 50.8 mm elevation drivers, six 50.8 mm midrange drivers, three 19.05 mm tweeters and a 101.6 mm subwoofer. Its 3.1.2 channel layout and support for 24‑bit Hi‑Res streaming, Dolby Atmos and Dolby TrueHD give it a full‑range, immersive soundstage that professionals praise for detailed treble and deep, distinct bass.

At 14.33 lb, the soundbar's heavier than the Bose Smart Ultra (12.68 lb) and considerably heavier than the Denon Home 550 (7.3 lb). Its 1211.58 mm length also exceeds the compact dimensions of the Samsung HW‑S61D and Polk Audio Signa S3, making it a more prominent fixture for larger living rooms. While the Bose model lists nine drivers, the Panorama 3’s 13 drivers provide a higher driver count, positioning it as the most driver‑rich option in this group.

User feedback repeatedly highlights the Panorama 3’s audiophile‑grade music reproduction and clear dialogue, with reviewers noting the integrated subwoofer’s “deep, distinct” bass. However, owners also complain about the remote’s impractical layout and the lack of expandability for additional surround speakers, which limits customization for larger home‑theater setups. The built‑in Alexa, AirPlay 2 and Spotify Connect add convenient voice‑controlled streaming, though the premium $999 price tag and a below‑average 3.1‑star rating from 54 reviews may give pause to cost‑conscious shoppers.
