Sonos Beam Gen 2 Review: Compact Soundbar Tested

The Sonos Beam Gen 2 sits in an interesting position: compact enough for most TV setups, capable enough to handle Dolby Atmos, and deeply integrated into the Sonos ecosystem. For anyone researching soundbars at the mid-range tier, it comes up constantly , and for good reason. The question worth answering is whether “good reason” holds up under scrutiny.

My path went through a soundbar phase before landing on discrete speakers, so the framing here is honest rather than promotional. Soundbars make real sense for a lot of living situations , rentals, shared walls, rooms that can’t support a full surround setup.

Quick Verdict

The Sonos Beam Gen 2 is a well-executed compact soundbar for buyers who want a clean setup, Dolby Atmos decoding, and access to the Sonos multiroom ecosystem without running speaker wire. It is not a substitute for discrete surrounds and a subwoofer , Sonos will tell you that too, and they sell the expansion hardware to prove it. For renters, apartment dwellers, or anyone who genuinely cannot place separate speakers, the Gen 2 is the strongest option at this size and price band. For buyers who have flexibility in their room, discrete separates will outperform it.

One calibration note: the Beam Gen 2 does not work with Audyssey, REW, or any third-party room correction. Sonos runs its own TruePlay calibration using the iOS microphone, and it is iPhone-only. Android users get a version that adjusts equalization without acoustic measurement. That is a real limitation worth knowing before purchase.

Performance

Dialogue Clarity

The Beam Gen 2 does one thing exceptionally well for a three-channel bar: center-channel dialogue. Verified buyer reports consistently cite this across AVS Forum threads and retailer reviews , the center image is stable, voices cut through clearly, and the speech intelligibility problem that plagues many compact bars is largely absent here. For anyone coming from a TV’s built-in speakers, the difference is significant.

Sonos uses five drivers , one tweeter, three midwoofers, and a passive radiator , plus internal processing to create a wider front soundstage than the physical enclosure suggests. Owner consensus confirms this works reasonably well for stereo content and center-anchored dialogue. It does not replace the physics of a separate center speaker in a real three-channel or 5.1 setup, but within its category, it performs well above average.

Bass and Low-End Extension

This is where honest framing matters. The Beam Gen 2 is a compact bar without a subwoofer. Low-end extension is limited by physics. For movie soundtracks that rely on LFE content , anything with significant sub-80Hz content , the bar rolls off early. Owner reports describe the low-end as “present but not impactful” and “fine for TV dialogue, thin for action sequences.” That is accurate.

Sonos’s own TruePlay calibration optimizes the frequency response for the listening room, which helps tonality but cannot manufacture bass extension the drivers cannot produce. The answer Sonos provides is the Sub or Sub Mini , both add meaningful low-end extension and are designed to integrate cleanly with the Beam ecosystem. That expansion path is worth knowing before purchase.

Dolby Atmos , Realistic Expectations

The Beam Gen 2 decodes Dolby Atmos via HDMI eARC. It does not have upward-firing drivers. The “height” effect is produced through signal processing and boundary reflections , the bar bounces sound off the ceiling to simulate overhead placement. Owner feedback on this is mixed: some listeners report a noticeable sense of height on well-mixed Atmos content; others find it modest at best. The honest summary from AVS Forum owner reports: it is better than no Atmos processing, and it is not close to what a bar with physical upward-firing drivers produces, let alone discrete Atmos height channels.

For reference, the Sonos Arc , the larger sibling , uses 11 drivers including upward-firing tweeters, and the height effect is consistently rated more convincing. The Beam Gen 2 is a three-channel bar that decodes Atmos metadata; it is not an Atmos height speaker system.

Ecosystem and App

Sonos’s ecosystem integration remains its clearest competitive advantage. Multiroom audio, AirPlay 2, Spotify Connect, and control via the S2 app all work reliably. Owner consensus is that the app experience is smooth once set up, though the 2024 Sonos app redesign drew significant negative feedback from the community , many users reverted to older app versions where possible. This may have improved by the time you are reading this, but it is worth checking current community sentiment on the Sonos subreddit and AVS Forum before purchasing.

Top Picks

Sonos Beam Gen 2 - Black

The Sonos Beam Gen 2 - Black is the standard recommendation for buyers who have already decided a soundbar is the right form factor. Black is the more popular finish , it disappears against most dark TV bezels and entertainment furniture without drawing attention to itself.

The critical hardware upgrade from Gen 1 is the HDMI eARC port. The original Beam connected via optical adapter, which limited audio formats to Dolby Digital 5.1 , no Atmos passthrough. Gen 2’s eARC port unlocks Atmos decoding directly from the TV’s audio return channel, which is a meaningful functional improvement. If your TV has an eARC-capable HDMI port, the Gen 2 uses it properly.

Owner reports are consistent on a few points: setup through the Sonos app is fast, dialogue clarity is strong, and the three-channel soundstage punches above its size. The limitation that comes up most is low-end , buyers expecting meaningful bass without the Sonos Sub will be disappointed. Frame the purchase accordingly: the Beam Gen 2 black is a strong compact bar that scales up if you add Sonos expansion hardware later.

Sonos Beam Gen 2 - White

The Sonos Beam Gen 2 - White is the same hardware in a finish that pairs well with white or light-colored TV stands, IKEA media units, and wall-mounted setups where the bar is visible against a light wall. Functionally identical to the black version , same drivers, same processing, same eARC port, same TruePlay calibration, same Atmos decoding.

Finish choice here is purely aesthetic. Owner reports on the white version note that the fabric grille shows dust more readily than the black variant, which is worth knowing if the bar will sit on open shelving. Otherwise the decision comes down to what looks right in the room.

If you are wall-mounting the Beam, Sonos sells a dedicated wall mount bracket separately , white finish buyers in particular tend to prefer the mounted look since it integrates cleanly with the TV installation. The bracket is not included and worth accounting for if that is your plan.

Sonos Beam (Gen 1) - Black

The Sonos Beam (Gen 1) - Black connects via optical cable , or the included HDMI optical adapter , which limits audio format support to Dolby Digital 5.1 and stereo PCM. No Atmos decoding. That is the functional ceiling of the Gen 1 hardware, and it is the reason the Gen 2 exists.

For buyers who have found a Gen 1 unit at a meaningfully reduced price point and do not have a TV with eARC, the Gen 1 is not a bad bar. Dialogue clarity and ecosystem integration are the same strengths. Sonos still supports the Gen 1 in the S2 app. The internal driver configuration is slightly different , four midwoofers versus the Gen 2’s three plus tweeter arrangement , and owner reports suggest the Gen 1’s tonal balance is warmer and slightly less detailed in the upper midrange.

The honest framing: if the Gen 2 is available at any reasonable price differential, it is the correct choice. The eARC port and Atmos decoding are not marginal upgrades. The Gen 1 makes sense only if the price difference is substantial and Atmos support is not a priority.

Buying Guide

Connection: HDMI eARC vs. Optical

This is the most important hardware decision in this category. HDMI eARC carries uncompressed and object-based audio formats , Dolby Atmos, DTS:X, and lossless multichannel PCM , from the TV to the soundbar. Optical cable is bandwidth-limited to compressed Dolby Digital 5.1 at best, which means Atmos metadata is stripped before it reaches the bar. The Beam Gen 2’s eARC port is not a minor upgrade , it changes what audio formats the bar can actually decode. Before purchasing any soundbar in this category, confirm your TV has an eARC-labeled HDMI port and that eARC is enabled in the TV’s audio settings.

Channel Count and What It Means in Practice

The Beam Gen 2 is a three-channel soundbar: left, center, right. There are no physical surround or height channels in the bar. Atmos processing is virtual , it uses signal processing and room reflections, not dedicated upward-firing or side-firing drivers. Owner consensus is that the front soundstage is wide and the center image is solid, but discrete surround information and genuine overhead effects are not reproducible from three forward-facing channels. If discrete surround sound is a priority, the honest answer is either a larger bar with more drivers or a full separates setup. The soundbar category as a whole involves this trade-off , channel count matters.

Subwoofer and Expansion Ecosystem

No subwoofer is included with the Beam Gen 2. Low-frequency extension from the bar alone is limited. Sonos offers the Sub (full-size) and Sub Mini (compact) as expansion hardware that integrates cleanly with the Beam , both connect wirelessly and are calibrated through TruePlay. Owner reports consistently rate the Sub Mini as a meaningful upgrade for buyers who want more bottom-end impact without a large cabinet. Sonos also offers surrounds via the Era 100 or Era 300 speakers. The expansion path is coherent and works reliably within the Sonos ecosystem; each piece is priced separately, and the full expanded system adds up quickly.

TruePlay Calibration and Platform Limitations

Sonos TruePlay uses the microphone on an iOS device to measure the acoustic response of the room and adjust the bar’s equalization accordingly. The calibration is automatic and takes under two minutes. Android users get a simplified version that applies EQ adjustments without acoustic measurement. There is no support for third-party measurement tools like REW or external microphones. For buyers who calibrate their own systems, this is a real constraint , the measurement and correction process is entirely inside Sonos’s ecosystem and not user-adjustable beyond bass and treble sliders in the app.

Voice Assistants and Privacy Considerations

The Beam Gen 2 has Amazon Alexa and Google Assistant built-in , always-on microphones are active by default. A physical microphone mute button is present on the top panel. Owner reports note that voice assistant reliability is good for music playback and basic smart home commands, but audio routing decisions , switching inputs, adjusting processing modes , still require the app. Buyers who prefer not to have always-on microphones should engage the hardware mute. Those coming from a non-smart-speaker environment should read Sonos’s privacy policy before purchase. Browse soundbar options broadly if this is a deciding factor , not every bar in the category includes integrated voice assistants.

Frequently Asked Questions

Does the Sonos Beam Gen 2 support DTS:X?

No. The Beam Gen 2 decodes Dolby Atmos but does not support DTS:X. DTS-encoded audio is processed and output as stereo PCM. For most streaming content and Blu-ray discs, Dolby Atmos is the more common format, so this limitation is rarely encountered day-to-day.

What is the difference between the Sonos Beam Gen 1 and Gen 2?

The most significant difference is the addition of HDMI eARC in the Gen 2, replacing the optical-only connection of the Gen 1. eARC allows the Gen 2 to receive and decode Dolby Atmos, which the Sonos Beam (Gen 1) - Black cannot do. The Gen 2 also uses a different internal driver configuration , one tweeter plus three midwoofers versus the Gen 1’s four-midwoofer layout , which reviewers describe as slightly more detailed in the upper midrange. Both generations are supported in the Sonos S2 app.

Do I need the Sonos Sub to enjoy the Beam Gen 2?

No , the Beam Gen 2 functions as a standalone bar, and many buyers use it without a subwoofer. The limitation is low-frequency extension: the bar rolls off bass content meaningfully below around 60Hz. For TV dialogue and moderate volume movie watching, owner reports find it acceptable. For action-heavy films or music with significant low-end, the Sonos Sub Mini or Sub is a substantial upgrade.

Can I add surround speakers to the Sonos Beam Gen 2?

Yes. The Beam Gen 2 supports Sonos Era 100 or Era 300 speakers as wireless surrounds. They connect and configure through the Sonos app without running speaker wire. The Era 300 includes upward-firing drivers, which adds genuine Atmos height information to the surround channels , a meaningful upgrade for Atmos content.

Is TruePlay calibration required for the Beam Gen 2 to work properly?

No , the Beam Gen 2 operates without running TruePlay. Calibration is optional but recommended. Without it, the bar applies a default equalization curve. Owner consensus is that TruePlay makes a noticeable improvement in tonal balance, particularly in rooms with hard reflective surfaces or unusual speaker placement.
