Soundbars
A soundbar is the fastest way to fix bad TV audio without rewiring a room. Modern TVs are thin, and thin cabinets don't leave room for speakers that can move real air, so almost every TV sounds thin and unclear on dialogue. A single bar sitting under or in front of the screen solves that with one HDMI cable and no separate amplifier to configure.
Soundbars trade some performance for that simplicity. Even a very good bar can't match a proper 5.1 speaker-and-receiver setup for separation and dynamics, because the drivers are close together and the processing is doing a lot of the work that dedicated left/right/center channels would otherwise do. For a lot of living rooms, that tradeoff is the right one — the question is which bar gets you closest to real surround sound for the money.
Below we cover what actually matters when shopping (channel count, Dolby Atmos, subwoofer inclusion, HDMI eARC) and link to our current soundbar picks and a guide on choosing between a soundbar and a full AV receiver system.
What to look for
Channel count tells you more than the marketing name
A bar labeled '5.1.2' has 5 main channels, a dedicated subwoofer, and 2 upward-firing drivers for height effects. More channels generally means better separation between dialogue, effects, and music, but only if the room can support it — upward-firing height channels need a flat ceiling a few feet above the bar to bounce sound off of.
Make sure it has HDMI eARC, not just optical
HDMI eARC (enhanced Audio Return Channel) passes lossless formats like Dolby Atmos and DTS:X from your TV apps and connected devices back to the soundbar over a single cable. An optical connection works but caps you at compressed 5.1 audio at best, so confirm both your TV and the bar support eARC before buying.
A separate subwoofer almost always beats a built-in one
Bass needs room to move air, and a slim bar cabinet doesn't have that room. Nearly every soundbar worth buying ships with (or offers) a wireless subwoofer box — that's a feature, not an upsell, and it's the single biggest factor in whether movies and music actually have impact.
Decide if you need rear surround speakers
Many 'virtual surround' bars use reflected sound and processing to simulate rear channels, which works reasonably well in smaller, boxier rooms with close side walls. If your room is open-plan or oddly shaped, look at a system that includes physical rear satellite speakers instead of relying on virtualization.
