The Bose Smart Soundbar 900 is an upgraded version of the Bose Smart Soundbar 700. Unlike its predecessor, it supports Dolby Atmos content, which is commonly found on both streaming platforms and Blu-rays. This premium soundbar comes with the manufacturer's PhaseGuide technology, which beams sound throughout your room for a more immersive listening experience. You can even upgrade it with a separate subwoofer and satellites as the Bose Smart Soundbar 900 with Speakers + Bass Module.

Our Verdict

7.5 Mixed Usage

The Bose Soundbar 900 is satisfactory for mixed usage. This soundbar has a balanced sound right out of the box, with a clear reproduction of dialogue in TV shows and instruments in your favorite tunes. It does well as a standalone bar, but without a dedicated sub, it doesn't bring the deep thump and rumble in the low-bass. You'll also need to add on satellites separately for a better surround sound.

Pros
  • Bass and treble adjustments.
  • Gets loud.
  • Supports Dolby Atmos content.
Cons
  • Lacks low-bass.
7.6 Dialogue/TV Shows

The Bose Soundbar 900 is good for dialogue-centric TV shows and podcasts. It reproduces voices with clarity and accuracy, and its discrete center channel improves vocal reproduction in the mix. There's even a dialogue enhancement mode to make voices more crisp. Unfortunately, it lacks an auto-volume mode, so you can't balance the volume level across different programs like with other premium bars.

Pros
  • Dialogue enhancement mode.
  • Bluetooth, Wi-Fi, and Apple AirPlay 2 support.
Cons
  • No auto-volume mode.
7.8 Music

The Bose Smart Soundbar 900 is good for music. Its room correction feature, which Bose calls ADAPTiQ, automatically optimizes audio reproduction based on the acoustics of the room you're in. It has a balanced sound that's suitable for many different music genres. You can customize its sound using its bass and treble adjustments, but it lacks a full EQ to customize across the range. You also don't get a very extended low-bass on its own, though you can add a subwoofer separately if you want.

Pros
  • Bass and treble adjustments.
  • Gets loud.
Cons
  • Lacks low-bass.
7.3 Movies

The Bose Smart Soundbar 900 is satisfactory for movies. This soundbar supports many audio formats commonly found on both streaming platforms and Blu-rays, like Dolby Digital and Dolby Atmos. Dialogue is clearly reproduced, though you don't get a deep rumble in the bass during action-packed scenes. The lack of satellites means you don't get the same all-around feel as with other premium bars, either.

Pros
  • Bass and treble adjustments.
  • Supports Dolby Atmos content.
Cons
  • Lacks low-bass.
  • Mediocre surrounds performance.
  • 7.5 Mixed Usage
  • 7.6 Dialogue/TV Shows
  • 7.8 Music
  • 7.3 Movies

The Bose Soundbar 900 has a satisfactory stereo frequency response. Thanks to its room correction feature, which Bose calls ADAPTiQ, you can optimize its audio reproduction based on your room's unique acoustic characteristics. With this feature on, the bar has a pretty balanced sound profile, especially in the mids, where most vocals and lead instruments reproduce. You get a little extra punch in the bass range to help bring bass-heavy music to life. Overall, it's suitable for listening to many different types of audio content, with clear dialogue in TV shows and movies as well as detailed voices and instruments in your favorite music. That said, your seat doesn't shake in action-packed scenesโ€”as with most standalone bars, it lacks an extended low-bass. You can always take a look at the Bose Smart Soundbar 900 with Speakers + Bass Module if you want more thump and rumble in the mix, though.

Similar to the Bose Smart Ultra Soundbar, this setup has features like Phaseguide that are designed to play stereo content through more than usual channels for a more immersive sound. You notice audio playing from the center channel as well as the left and right stereo channels. This results in a wider and more dimensional sound.

Stereo Soundstage
Crosstalk Error

Its stereo soundstage is great. Its soundstage is perceived to be very wide, and sound seems to reach the room's side walls. However, this can sound a bit unnatural and overdone. Its focus is mediocre, so instruments in the mix seem to come from a more general area rather than a pinpoint location in the space around you. For a setup with a better soundstage, see the Sony HT-A9.

It has very good stereo dynamics. This soundbar gets loud enough to fill up a large room or a crowded party. However, there's some compression when you push it to max volume, meaning you notice some pumping artifacts when you crank up the volume.

The Bose Soundbar 900 has a satisfactory stereo THD performance. At a normal listening volume, it falls within good limits, meaning audio reproduction is clean and pure. However, there's a jump in THD when you push the bar to max volume, especially in the mid-range. It's not very noticeable with real-life content, though, so it's not an issue unless you're an astute audiophile.

This 5.0.2 soundbar has a discrete center channel to improve vocal reproduction in the mix. The frequency response on this channel is very balanced, too, especially in the mids where most dialogue is reproduced. As a result, it's easy to follow along with conversations on screen.

The Bose Soundbar 900 has a mediocre surround performance, which is expected for a standalone bar. It doesn't have discrete surround speakers, so it uses side-firing and up-firing drivers in the bar itself to ricochet sound around your room. It attempts to simulate sound effects in the space around you, but it doesn't perform as well as a discrete setup would. Audio tends to be focused in the space in front of you rather than stretching all around you. However, you can check out the Bose Smart Soundbar 900 with Speakers + Bass Module if you want an improved surround sound experience.

Unlike the Bose Smart Soundbar 700, this bar supports Dolby Atmos content. It has two up-firing drivers built into the bar that bounce sound off the ceiling and back down toward you to create the illusion of height. It isn't quite as immersive-sounding as the discrete localization provided by home theater setups, but it's a similar setup to other Dolby Atmos soundbars. Overall, sound effects are clear and detailed, and there's a little extra rumble due to the bass-heavy sound profile on these channels.

Subjectively, the bar can reproduce a wide soundstage that makes it seem like the action on screen is happening around you. Cars seem to race past you in chase scenes, and drones feel like they're flying from overhead, replicating more height than with other standalone Atmos setups like the Sennheiser AMBEO Soundbar Plus. That said, the bar's subjective performance isn't quite as accurate as the full setup with speakers and a subwooferโ€”you can tell that the bar tries to achieve spatial wideness and height, but it's a bit exaggerated. Still, compared to other standalone bars, it offers a really impressive sound.

The Bose Soundbar 900 has a few sound enhancement features. You don't get an EQ, so you can only customize it with its included bass and treble adjustments. On the upside, like the Bose Smart Ultra Soundbar, there's a room correction feature called ADAPTiQ, which adjusts the bar's audio based on the unique layout of your living room.

You can connect the Bose Smart Soundbar 900 to your TV using its Optical or HDMI ports. The 'ADAPTiQ' port is for the headset included so you can listen in while calibrating the bar to your room's unique acoustics. However, it lacks a Full HDMI In port, so you can't use it as a hub between different devices.

It has fairly low latency via ARC and Optical, so the audio you hear is in sync with the video you see on the screen. As a result, it's a great choice for watching movies, sports, and video games, among others. Certain apps and TVs compensate for latency differently, though.

The bar has a strip of light that flashes different patterns and colors depending on the settings you adjust. If you turn up the volume, it lights up to the right and fades to the left, and if you turn down the volume, it does the opposite. While the display isn't very intuitive, you can learn the different patterns using the manual.

Additional Features
Bar Controls

On top of the bar, there are two touch-sensitive buttons. You can use the 'Microphone Off' button to disable voice assistants, and the 'Action' button lets you manually activate voice assistants and silence alarms and timers. The 'Action' button doesn't activate the voice assistant while the microphone is off.

Additional Features
Remote

The remote is pretty simple and lets you control some functions like volume and change the input. However, you have to use the Bose Music app to access some of its additional features, like if you want to connect the bar to other compatible speakers in your house.
