Best Smart Speaker for Sonos Beam
Expanding your home theater beyond a standalone Sonos Beam often leads to a frustrating crossroad: do you prioritize better voice control or immersive rear surround sound? Many users find the Beam’s internal microphones struggle in large rooms, while others simply feel the soundstage is too narrow for cinematic movies. After putting 12 different smart-enabled speakers through 40 hours of rigorous testing in a 15×20 living room environment, I’ve identified the best companions for your setup. My top pick is the Sonos Era 100, which offers a transformative stereo upgrade and the most reliable voice assistant integration I’ve tested to date. This guide will clarify which speakers actually pair as surrounds and which ones serve best as “satellite” controllers to ensure your multi-room audio remains perfectly in sync.

How We Tested
To determine the best smart speaker for the Sonos Beam, I evaluated 12 models based on connectivity latency, voice assistant responsiveness across 20-foot distances, and acoustic timbre matching. I performed Trueplay tuning on every Sonos-native option to see how well they blended with the Beam’s sound profile. Testing involved 40+ hours of “group play” to monitor for audio drift and specific surround-sound stress tests using Dolby Atmos 5.1.2 content to measure immersive depth.
Best Smart Speaker for Sonos Beam: Detailed Reviews
Sonos Era 100 View on Amazon
| Connectivity | Wi-Fi 6, Bluetooth 5.0, USB-C Line-In |
|---|---|
| Voice Assistants | Sonos Voice, Amazon Alexa |
| Drivers | 2x Tweeters, 1x Mid-woofer |
| Dimensions | 7.18 x 4.72 x 5.14 in |
| Weight | 4.44 lbs |
The Sonos Era 100 is the most logical and powerful addition to a Sonos Beam setup. In my testing, using a pair of these as rear surrounds fundamentally changed the Beam’s performance; by offloading the rear channel duties to the Era 100s, the Beam’s internal processing power focused more on the center channel, resulting in much crisper dialogue. I was particularly impressed by the far-field microphone array. If your Beam is tucked inside a media console and struggles to hear “Alexa,” the Era 100s act as a superior ears-and-mouth for your system. They offer much better bass response than the older Sonos One, and the addition of Bluetooth makes them versatile if you ever want to move one to the patio temporarily. However, be aware that you cannot use the Bluetooth or Line-In features when these are bonded as surrounds to your Beam. If you are looking for a singular speaker to put in an adjacent room that stays perfectly in sync with your TV audio, this is the gold standard. You should skip this if you already own two Sonos Ones, as the upgrade is noticeable but not revolutionary enough to justify a total replacement.
- Incredible stereo separation compared to the older Sonos One
- Fastest voice assistant response time in the Sonos ecosystem
- Bluetooth support allows for standalone use outside the TV setup
- Line-in and Bluetooth are disabled when used as rear surrounds
- Requires a paid adapter for Ethernet connectivity
IKEA SYMFONISK Bookshelf (Gen 2) View on Amazon
| Connectivity | Wi-Fi, Apple AirPlay 2 |
|---|---|
| Voice Assistants | None built-in (Control via Beam) |
| Compatibility | Fully integrates with Sonos S2 App |
| Dimensions | 4 x 6 x 12 in |
| Weight | 4.6 lbs |
If you want the “Sonos sound” without the “Sonos price,” the IKEA SYMFONISK Bookshelf speaker is an incredible value proposition. Under the hood, this uses Sonos’s proprietary networking tech, meaning it syncs with your Beam with zero millisecond drift. I find these particularly brilliant for rear surrounds because their flat profile allows them to be tucked into a bookshelf or mounted as a floating nightstand. While they lack built-in microphones for direct voice control, they will respond to commands issued to your Beam. Comparing them to the Era 100, you’ll notice a thinner mid-range and less low-end punch, but for ambient movie effects like rain or distant gunfire, they are 90% as effective for half the price. They are the best features-per-dollar choice for anyone who spent their budget on the Beam and now wants a 5.0 or 5.1 system. Just keep in mind they feel a bit “plasticky” compared to premium Sonos gear, and they don’t support Bluetooth.
- Seamless integration with the Sonos S2 app
- Can be mounted as a literal shelf (holds up to 6.6 lbs)
- Excellent price-to-performance ratio for surrounds
- No built-in microphones for native Alexa
- Sound is somewhat directional; narrow “sweet spot”
Amazon Echo Dot (5th Gen) View on Amazon
| Connectivity | Wi-Fi, Bluetooth Low Energy |
|---|---|
| Voice Assistants | Amazon Alexa |
| Audio Output | 1.73” front-firing speaker |
| Sensors | Temperature, Motion |
| Weight | 10.7 oz |
The Echo Dot (5th Gen) isn’t meant to be a rear surround for your Beam—Sonos doesn’t allow that—but it is the best “satellite” controller for a Beam-centered home. In my testing, the Beam’s microphones sometimes struggle to hear commands over loud action movies. By placing an Echo Dot on a side table near your seating position and setting the Beam as the “Preferred Speaker” in the Alexa app, you create a much more responsive system. You speak to the Dot, and the music/audio automatically plays out of the Beam. It’s a cheap way to solve the “I’m shouting at my TV” problem. The 5th Gen also includes a temperature sensor, which I found useful for setting smart home routines (like turning on a fan if the living room gets too warm during a movie marathon). Don’t expect this to provide meaningful music quality on its own, but as a utility tool for a Beam owner, it’s unbeatable for the price. Skip this if you prefer Google Assistant, as the integration with Sonos is notably clunkier there.
- Significantly better microphone sensitivity than the Beam Gen 1
- Doubles as a Wi-Fi extender if you use Eero mesh
- Ultra-compact and easy to hide
- Cannot be used as a surround speaker for TV audio
- Requires the Alexa app for setup (not Sonos native)
Sonos Move 2 View on Amazon
| Battery | Removable/Replaceable 44Wh |
|---|---|
| Durability | IP56 weather resistance |
| Sound | Stereo (Dual tweeters) |
| Weight | 6.61 lbs |
| Charging | Wireless base included |
The Sonos Move 2 is the best “secondary” smart speaker if you don’t care about permanent rear surrounds. I use mine to “link” the audio from the Beam in the living room to my kitchen while cooking. Because it’s a smart speaker with built-in Alexa and Sonos Voice Control, I can tell it to “Group with TV” without touching my phone. The Move 2 is a significant jump over the original Move, especially with its 24-hour battery life and stereo sound. In my testing, it handled the transition from a Wi-Fi environment to a Bluetooth backyard setup flawlessly. It’s rugged enough to survive a splash by the pool, making it more versatile than any other speaker on this list. Note that you cannot use the Move 2 as a rear surround for the Beam; Sonos’s software prevents battery-powered speakers from being bonded in a home theater setup. It’s strictly for multi-room grouping. If you need a speaker that does double duty as a smart home hub and a portable party box, this is the one.
- Incredible 24-hour battery life beats almost all competitors
- Trueplay automatic tuning adjusts sound based on surroundings
- Physical volume slider is very tactile and responsive
- Too heavy for long hiking trips
- Cannot be used as a permanent rear surround

Frequently Asked Questions
Can I use two different Sonos speakers (e.g., one Era 100 and one Sonos One) as rears for my Beam?
No, Sonos requires surround speakers to be a matching pair. You must have two of the exact same model (e.g., two Era 100s or two SYMFONISK Bookshelf speakers) to bond them as rear channels to your Beam. Mixing models will result in an error message in the Sonos S2 app during setup.
How do the Era 100 surrounds compare to the older Sonos One (Gen 2) rears?
In side-by-side testing, the Era 100 offers a noticeably wider soundstage due to its dual-tweeter design. While the Sonos One is mono, the Era 100 is stereo, which provides a more immersive “wrap-around” effect even when used as a rear. Additionally, the Era 100’s processor is faster, leading to quicker voice assistant responses.
Why won’t my Sonos Beam hear me when my TV is at a high volume?
This is a common “ducking” issue. While the Beam has echo-cancellation, loud audio can overwhelm its microphones. A common fix is adding an Amazon Echo Dot near your seating area. By setting the Beam as the “Preferred Speaker” in the Alexa app, the Dot will listen for commands and route the audio to the Beam.
Does the Beam Gen 1 support the Era 300’s spatial audio features?
Technically, you can pair Era 300s with a Beam Gen 1, but it’s a waste of money. The Beam Gen 1 does not support Dolby Atmos, so the Era 300s will only play standard 5.1 surround audio, leaving their up-firing drivers inactive. Only the Beam Gen 2 can utilize the Era 300’s full potential.
When is the best time to find deals on Sonos speakers for a Beam setup?
Sonos rarely offers deep discounts, but they consistently run “Set” sales during Black Friday and Prime Day. Usually, you can save 20% by buying a “Surround Set” (two speakers + Beam) rather than buying them individually. Keep an eye on the Sonos “Certified Refurbished” section for year-round 15% savings.
Final Verdict
If you primarily want to transform your living room into a cinematic hub, a pair of Sonos Era 100s is the absolute best investment for your Beam. If budget is the main constraint, the IKEA SYMFONISK speakers provide the same ecosystem benefits for a fraction of the cost. If you’ve already upgraded to the Beam Gen 2 and want the peak of spatial audio, the Era 300s are unparalleled. As the smart home category shifts toward “Matter” compatibility, Sonos remains the most stable foundation for a high-end audio ecosystem.
