The Klipsch Cinema 400 is a 2.1 setup from the company's 2020 lineup. It comes with a dedicated subwoofer, which helps reproduce a present and punchy bass. Out-of-the-box, it has a very neutral sound profile suitable for listening to lots of different types of audio content. Unfortunately, there aren't a lot of sound customization features available. It also has to downmix surround content into stereo, and it doesn't support Atmos content.

Our Verdict

The Klipsch Cinema 400 soundbar is fair for mixed usage. Its balanced sound profile makes it suitable for listening to lots of different audio content. Even though it lacks a dedicated center channel, dialogue in TV shows is clear and accurate. You can also use its subwoofer level adjustment to customize its sound. However, it has to downmix surround content into stereo, which doesn't sound as immersive. It also doesn't support Dolby Atmos content.

Differences Between Sizes And Variants

If you come across another version, let us know in the discussions so we can update our review.

Compared To Other Soundbars

The Klipsch Cinema 400 is a 2.1 setup with a very neutral, balanced sound profile out-of-the-box that makes it suitable for listening to lots of different types of audio content. Unlike the Klipsch Cinema 600, it doesn't have a dedicated center channel, so dialogue-centric content doesn't sound as real or clear. That said, it comes with an auto-volume mode and an adjustable dialogue enhancement feature. See also our recommendations for the best soundbars under $300, the best soundbars for dialogue, and the best soundbars.

Yamaha YAS-209

The Yamaha YAS-209 and the Klipsch Cinema 400 are both very similarly performing 2.1 setups, but depending on your listening habits, you may prefer one over the other. The Klipsch has a better-balanced sound profile out-of-the-box, and it also comes with more sound enhancement features, including an auto-volume mode. However, the Yamaha is better-built, and it has a better soundstage performance. Unlike the Klipsch, it also comes with a Full HDMI In port.

Klipsch Bar 48

The Klipsch Cinema 400 is a better soundbar than the Klipsch Bar 48. The Cinema 400 has a more neutral, balanced sound profile, so it's suitable for lots of different types of audio content. However, the Bar 48 is better built, and it has a better center channel performance thanks to its 3.1 setup.

The Sony HT-G700 is better for mixed usage than the Klipsch Cinema 400. The Sony is a better built 3.1 setup that supports Dolby Atmos content, unlike the Klipsch.

The Klipsch Cinema 400 is a bit wide, so it may not fit between the legs of your 55" TV. However, it isn't very tall, so it shouldn't block your TV screen unless your TV sits flush on your table.

The Klipsch Cinema 400 has an impressive stereo frequency response. When set to its default 'Natural' preset, it has a very neutral, balanced sound profile suitable for listening to lots of different audio content. It has a present, punchy mid and high-bass, but you don't really feel the deep rumbles from the low low-bass. You can use the subwoofer level adjustment to customize its sound more to your liking.

With calibration, this soundbar offers a great stereo frequency response. When set to its 'Natural' preset and with the bass setting set to '-3' using the subwoofer level adjustment, it reproduces a very neutral, balanced sound profile. You really feel the deep thumps and rumbles in the low-bass, which is ideal for fans of action-packed movies and bass-heavy music.

Stereo Soundstage

1.88 dB

The Klipsch Cinema 400 has a reasonable stereo soundstage performance. The soundstage is perceived to be about as wide as the bar itself, but it doesn't have any tricks to make it seem wider than that. Also, it has good focus, so objects like voices and footsteps seem to be coming from an accurate, pinpoint location instead of a more general area.

The Klipsch Cinema 400 has adequate stereo dynamics. It can get pretty loud, but other soundbars we've tested, like the Klipsch Cinema 600, can get louder. There's also some compression when you play it at max volume, which is disappointing.

The Klipsch Cinema 400 has a decent stereo THD performance. At normal listening volumes, you get clean and pure audio reproduction. However, at max volume, there's a jump in THD, but it may not be audible with real-life content.

The Klipsch Cinema 400 has a disappointing center channel performance. Since it's a 2.1 setup, it doesn't have a dedicated center channel. Instead, it uses its left and right channels to create a phantom-localized center, but this doesn't sound as clear or real as a discrete center. Though it has a bass-heavy sound profile, there isn't a lot of bass reproduced on this channel, so it shouldn't be too much of an issue with real-life content.

Update 03/30/2021: For consistency across our reviews, we updated the result for EQ from 'Presets' to 'No'. The 'Voice' preset is a dialogue enhancement feature, and the 'Night' feature is an auto-volume mode, so both of these features are already taken into account in our results.

This soundbar has a middling selection of sound enhancement features. Its 'Night' feature disables the subwoofer and reduces the dynamic range, which is convenient if you prefer a lower volume while maintaining all the sounds of your audio. You can also cycle between three different levels of its 'Voice' dialogue enhancement feature, so you can make the dialogue louder or quieter depending on your preferences. That said, this soundbar lacks more premium sound enhancement features like room correction or a full graphic EQ.
