How to Choose a Soundbar (2026 Buyer’s Guide)
TV speakers keep getting worse because TVs keep getting thinner. Thats the whole reason soundbars exist. The trouble starts when you go shopping and hit a wall of names like 2.0, 3.1.2, and 5.1 with prices from $60 to $900, and no obvious reason why. This guide decodes the numbers so you can match a bar to your room instead of buying whatever is on sale.
Quick note before we get into it. If you just want a shortlist to pick from, we already lined up five bars against the most famous one in our Sonos Beam alternatives roundup. This page is for figuring out what you actually need first.
The Channel Numbers, Decoded
The digits describe how many speakers you get. The first number is regular channels, the second is subwoofers, the third (when there is one) is upfiring Atmos drivers. So a 2.0 bar is stereo only, a 3.1 has left, right, a center channel, and a subwoofer, and a 5.1.2 adds surrounds plus two drivers aimed at your ceiling.
The number that matters most is hiding in the middle. That 3 means a dedicated center channel, and the center channel is what carries dialogue. If you rewind shows because voices get buried under music, a 3.1 bar fixes your actual problem, no Atmos required. For most living rooms, 3.1 is the sweet spot.
The Subwoofer Question
Bass is the difference between hearing an explosion and feeling one, and thin bars cant produce it alone. Most mid range bars ship with a wireless subwoofer that just needs a power outlet. Movie and game people should get the sub, full stop.
Apartment dwellers have a real decision though. A sub firing through the floor at 11pm is how you meet your downstairs neighbors. A bar only setup with decent built in woofers is the diplomatic option, you can always add the sub in a house later.
Connections: eARC Is the One to Look For
Three ways to hook a bar to a TV. Optical is the old reliable, it works everywhere but cant carry lossless audio and needs its own remote juggling. HDMI ARC passes decent quality sound and lets your TV remote run the volume. HDMI eARC is the newer version with enough bandwidth for lossless Atmos, and its what you want if you ever plan to go beyond basic stereo.
Flip your TV around and read the port labels before you buy anything. One of the HDMI ports will say ARC or eARC on the sticker. If your TV only has ARC, dont pay a premium for lossless audio features the connection cant deliver, thats money down the drain.
Match the Bar to the Room
A giant 5.1.2 system in a 10 by 10 bedroom is like putting a truck engine in a go kart. Small rooms do fine with a 2.1 or compact 3.1. Big open plan living rooms benefit from more channels and more power because the sound has to fill more space.
Size the bar to the TV too. The usual advice is a bar about as wide as your screen or a bit narrower, it looks right and the stereo image lines up with the picture. And measure the gap under your TV, some bars sit tall enough to block the bottom edge of the screen or the IR sensor, which gets old fast.
Features Worth Paying For (and Ones That Arent)
Room calibration, where the bar plays test tones and tunes itself, makes a real difference and is worth having. Dialogue enhancement modes earn their keep if anyone in the house struggles with mumbly actors. Night mode, which squashes loud effects so you can watch late, is quietly one of the most used features on any bar.
Built in streaming is the one to think twice about. Plenty of bars bundle WiFi streaming platforms into the price, but if your TV already streams or you use a stick, youre paying for a duplicate. We covered the streaming box side of this in our Sonos Beam review, where half the price is the smart platform. Decide if you want smarts in the bar or just good speakers.
The 60 Second Checklist
- Dialogue problems? Get a bar with a center channel (3.1 or up).
- Movies and games, get the sub. Downstairs neighbors, maybe skip it.
- Check your TV for an eARC port before paying for Atmos anything.
- Bar width roughly matches the TV, and it shouldnt block the screen.
- Skip built in streaming if something you own already streams.
