The Sennheiser AMBEO Soundbar MAX is a 5.1.4 setup with 13 speakers that delivers an impressive immersive experience for a standalone bar. This system has a unique 3D mode that helps sounds come from over and around you, without the need for wireless speakers. The bar gets very loud, but unfortunately, it's a bit on the bass-light side, especially with stereo content. On the other hand, it has a lot of inputs and supports pretty much every audio format.
Our Verdict
The Sennheiser AMBEO Soundbar MAX is great for mixed usage. It has a unique 3D mode that greatly improves the surround performance, which is great for movies. Its overall sound profile is pretty accurate, but it's lacking a bit in the bass range. While the bar still produces a good amount of bass, it's audibly lower than other frequencies at the same volume, which gives it a disappointing feel on stereo bass-heavy content like some music genres. On the upside, it has a room correction feature that adapts to your room and the reproduction of voices in accurate and clear.
- Impressive immersive sound for a stand-alone bar.
- Good performance with surround content.
- Supports all audio formats.
- Well-built design.
- Very heavy.
- Disappointing bass performance, especially on stereo content.
The Sennheiser AMBEO Soundbar MAX is excellent for dialogue-focused TV shows. It has a good overall sound profile with accurate mid-range performance, resulting in an accurate reproduction of voices with content like audiobooks, podcasts, or voices in TV shows. It lacks a bit of bass, but this shouldn’t be too bad for this use. On the upside, the bar can get very loud and has a few features like a dialogue enhancement and a night mode for a better listening experience. You’re also able to stream content wirelessly via Bluetooth, Wi-Fi, and use its built-in Chromecast.
The Sennheiser AMBEO Soundbar MAX is good for music. Without AMBEO mode, the volume of the bass is much lower than with it on. However, it performs quite well for music genres that don’t have that much bass. Also, it has a room correction feature to tweak out its sound quality depending on your room. The soundstage is decent and the bar performs well at max volume, which is pretty loud.
The Sennheiser AMBEO Soundbar MAX is good for movies. When using the AMBEO 3D mode, it's quite impressive and offers an immersive listening experience with movies thanks to the high number of speakers and the support for Atmos content. It performs well with surround sound movies overall and you’ll have the impression that the objects are localized around and over you, which is impressive for a stand-alone bar.

Popular Soundbar Comparisons
The Sennheiser AMBEO Soundbar MAX is a very unique product. This stand-alone bar has 13 speakers and tries to do it all in a single 5.1.4 unit. It does a decent job with most content and gives an impressive and immersive listening experience when using the AMBEO mode. However, this is the biggest and heaviest bar we've reviewed so far, so it might be hard for some people to fit it in their home theater setup. See our recommendations for the best soundbars, the best Dolby Atmos soundbars, and the best soundbars 5.1.
The Sennheiser AMBEO Soundbar MAX and the Sonos Arc are both very premium standalone bars. The Sennheiser reproduces a more extended low-bass thanks to its integrated subwoofer. It supports more wireless playback options, and unlike the Sonos, it offers a graphic EQ, presets, and a Full HDMI In port. However, the Sonos is better built with a better soundstage performance. Unlike the Sennheiser, it has bass and treble adjustments and built-in voice assistant support. You can also upgrade it to the Sonos Arc with Sub + One SL Speakers for better performance.
The Sennheiser AMBEO Soundbar MAX and the KEF XIO are both premium all-in-one soundbars. The KEF has a fuller-sounding bass, with more mid and high bass, although the Sennheiser does have a deeper low-frequency extension, so it can reproduce the lowest notes in a Hans Zimmer score, although they're not especially loud. That said, the boost in the KEF's high bass can muddy up voices, and the Sennheiser is more controlled throughout its frequency response. Still, the deciding factor may be that the Sennheiser is very large and heavy, so it might be tricky for most to place, while the KEF has a sleek, stylish design and doesn't take up much more space than a regular soundbar. On the other hand, the Sennheiser is usually a little cheaper.
The Sennheiser AMBEO Soundbar MAX and the Samsung HW-Q990B are two very different soundbars. They're both premium setups with Dolby Atmos support, but the Sennheiser is a standalone bar, as opposed to the Samsung, which has a subwoofer and satellites. The Samsung's a more versatile pick, with more bass out-of-the-box and a better soundstage. It's better for surround sound and Dolby Atmos content, with more enhancement features on hand. If you don't have room for a sub and satellites, the AMBEO is a good alternative. Its large, heavy design isn't for everyone, though.
The Sennheiser AMBEO Soundbar MAX is better than the standalone Sony HT-A7000. The Sennheiser is a 5.1.4 setup with better center, surround, and Atmos performances. It gets louder than the Sony, and it reproduces a more extended low-bass. It also has a graphic EQ, which some users may prefer for sound customization. However, the Sony is better-built, and it has a better stereo soundstage.
