There's a New Breed of Dolby Atmos Soundbars

It used to be impossible to buy a Dolby Atmos soundbar for less than $800. Now you can get a good one for $450 (and less). So, what's the catch?

In October 2021, Sonos released a new-and-improved version of its entry-level soundbar, the Beam (Gen 2). And it's big new feature was that it supported Dolby Atmos and was priced under $500. Most Dolby Atmos soundbars cost in the region of $900 — like the flagship options from Sonos and Bose — but many cost well over that.

There are two big reasons why Dolby Atmos soundbars are typically expensive. First, it's expensive for manufacturers to get the licensing for Atmos certification; which gets them the software package that decodes and the renders the Atmos stream. And two, the best Dolby Atmos soundbars typically require more speakers to best take advantage of the immersive sound technology — and more speakers are more expensive.

But over the last few years Dolby has been working to get Atmos supported in as many products as possible — it wants to make Atmos as popular as stereo sound. As that relates to soundbars, a lot of times that means supporting both soundbars that have and don't have upward-firing drivers. And if a soundbar doesn't have upward-firing drivers, it can be a lot less expensive.

Atmos allows speakers to create virtual height and side channels. This fools your ears into thinking that that sounds are coming from your left, right, center and above. The Atmos software package that Dolby provides soundbar manufacturers is smart enough to figure out what kind of system it is — be a 2.0-channel soundbar or 7.1.2 home theater system — and then it renders audio so that it's as accurate and immersive as possible.

An Atmos soundbar doesn't need to have upward-firing drivers, though if you listen to two Dolby Atmos soundbars side by side, you'll be able to tell if one of them has them. Both soundbars are able to virtualize sound, but the one with actual speakers firing up at your ceiling is going to do a better job at making you feel like sound is actually coming from above you.

The Sonos Beam (Gen 2) has the same architecture and same exact speaker configuration (consisting of four full-range drivers, a center tweeter and three passive radiators) as the first Beam, which didn't and doesn't support Atmos. The new Beam's compatibility is thanks to improved processing power and eARC connection allow the new Beam to create virtual height and side channels, even without new drivers.

The new Beam isn't the only affordable Dolby Atmos soundbar. TCL's makes two, in the Alto 9+ ($300) and the Alto 8i ($180). And Monoprice and Sony both make one, too, in the Monoprice SB300 ($180) and Sony HTX8500 ($298). And, most recently, Denon announced the DHT-S217 ($249). But like the new Beam, none have upward-firing drivers.

All of these are part of this new breed of affordable Dolby Atmos soundbars — and you can expect more manufacturers to get in on the action. While they sound good and are perfectly fine, just know that they aren't the best way to experience Atmos. For that, you still want one that has true upward-firing drivers. Like the Sonos Arc or Bose Smart Soundbar 900.

Below, we've rounded up a few of our favorite Dolby Atmos soundbars that cost less than $500.

Sonos Beam (Gen 2)

$2,022.00

The Beam (Gen 2) is half as expensive as the company's flagship Arc ($899), but it has most all of the same functionality, including easy integration with other Sonos speakers, support for either Alexa or Google Assistant voice assistants, and Wi-Fi streaming. The main difference, other than size and power, is that the Beam lacks upward-firing drivers so even though it supports Dolby Atmos, it's not able to create as immersive of an experience.

Denon DHT-S217

Released in mid-2022, the Denon DHT-S217 is an affordable 2.1-channel soundbar that supports Dolby Atmos. It has integrated downward-firing woofers for impressive bass performance. And it has built-in Bluetooth for easy music streaming. But, of course, it lacks the upward-firing drivers necessarily to deliver the best Atmos experience.

It has built-in Bluetooth so you can easily use it for music streaming when not watching TV.
