4 bargain-priced soundbars that will instantly upgrade your TV's disappointing built-in sound — without breaking the bank

This is a great price for a good-quality compact soundbar: at just under $100, the LG S20A will give your TV an impressive audio upgrade thanks to its passive bass radiator, AI Sound Pro processing, and extra width and power. That'll seriously upgrade the audio from budget TVs, and its small size means it won't take up too much space.

When we reviewed the Sonos Beam (Gen 2) we said it is "the perfect soundbar for smaller spaces", and with $130 off the retail price this is way cheaper than our target price of $449: Best Buy is offering it for just $369, which makes it a brilliant buy. The Dolby Atmos is virtual as the Beam doesn't have up-firing speaker drivers, but it's quite impressive – and because this is a Sonos you can use it as part of a Sonos audio setup including multi-room. The sound is amazingly full and expansive for something so compact, even with impressive bass despite no external subwoofer.

With $150 off, this already keenly priced surround sound system drops to just $349.99. That's a low price for a punchy soundbar with two wireless rear speakers and a wireless subwoofer too, and if you have a compatible LG TV, the WOW Orchestra feature combines its speakers with the soundbar in order to give you even better audio. The 9-driver setup delivers room-filling spatial sound including Dolby Atmos and DTS:X, all without having to run wires around the room.

This soundbar is a step up from the excellent Samsung HW-SQ700F, which we gave four and a half stars out of five to: it sounds excellent, harmonizes well with its subwoofer, and it's designed to sound great whether you mount it flat against the wall or lay it along a table or TV unit. Side and top-firing speakers deliver impressive Dolby Atmos audio and it works with Samsung's Q-Symphony, which uses a compatible Samsung's TV's speakers as part of the sound system, for even more immersive audio. This is an impressive price cut, taking $200 off the usual sticker price.
