The main reason most people buy external soundbars for their projectors is they need more volume. If you get a wimpy speaker, you won’t get the big sound boost you’re looking for. All of the soundbars on this list can reach at least 90 decibels, which isn’t quite rock concert loud but is plenty to fill most rooms.

For the loudest soundbar, the  SAMSUNG HW-Q990B/ZA  is the only soundbar on the list capable of producing over 100 decibels. (Not sure if this is true now, but can’t find decibels)

Overall Sound Quality

Bass is the main thing lacking from the built-in speakers on projectors. They just don’t have the heft to produce deep, rumbling sound effects. Many soundbars have the same problem, making an external subwoofer a necessity if you want truly immersive sound.

Balance is important too, though. If there’s too much bass or the sound is too “dark” it can be hard to hear dialogue and other details. The best soundbars for home theaters have dialogue enhancement features and content-specific settings that maintain this balance between clarity and power.

Surround Sound

Soundbars are cheaper than speaker systems but they have an inherent flaw: they produce sound from a single source. That prevents them from emulating a sense of space and movement.

Modern soundbar manufacturers use technology to overcome this issue with varying degrees of success. The Dolby Atmos support on the Bose Smart Soundbar 600does a good job replicating the surround sound experience, and the Polk Audio Signa S4  is fairly immersive, as well.

For the best surround sound emulation, the Acoustic Beam technology employed by the Samsung HW-Q700A gives it a similarly immersive soundscape to a 3.1.2 system, effectively mimicking the movement and depth of a full speaker system.

Smart Features

If you have (or want) a smart home theater, getting a soundbar with voice control features built right in will be very handy. Amazon Alexa voice control is the most common system, and is supported on the Polk Audio Signa S4 , Samsung , and Bose Smart Soundbars. The Bose  soundbars both also support Google Assistant, giving them more versatility for different smart home set-ups.

Many soundbars offer speech-specific settings that are great for this kind of content.
