Most sound bars come with an additional speaker called a subwoofer, which is designed to provide extra bass. Subwoofers can be built in or come as an external box - but are they really necessary for an epic home movie night?
A great sound bar should ideally offer the complete package on its own, delivering audio that is crystal clear, detailed and natural without the need to pair it with additional devices such as speakers or a subwoofer. Sound bases in particular can deliver effective bass all by themselves. The extra bass created by a subwoofer should dramatically enhance movie audio and deliver those legendary Hollywood action scenes with the impact and power they deserve.
However, not all subwoofers do a good job and some can even ruin your entertainment experience. While we've found some flawless sound bars with excellent subwoofers, our tests have also uncovered models that produce excessive, uncomfortable bass levels when the subwoofer is turned on. Some subwoofers deliver bass notes so late it's distracting, making movie scenes that could have been great lose impact - you'll see the sudden explosion before you hear it. Others overpower sound and are so boomy you'll suddenly be scrambling for the remote to turn the volume down.
These are two of the models we've tested that have subwoofers. Read our reviews to find out whether they provide the right levels of bass.

If your TV isn't wall mounted, you may want to consider getting a sound base over a sound bar. Sound bases sit under your TV and are larger than sound bars so have more room for bigger speakers. Thus, they tend to produce better bass due to having larger drivers and better in-built amplification. A sound base has additional bass drivers for extra bass so shouldn't need a subwoofer.
