Amazon makes sound bars, because of course they do, and their 2.1 channel, 31.5" model is down to $79 right now. While not an all-time low price, that is its first discount from $100 since July.
This bar’s integrated subwoofer won’t give you the kind of bass you’d expect from a dedicated subwoofer that sits on the floor, but it’s better than nothing, and makes this system ideal for a bedroom TV where space is a concern.
