For TV Sound
Q: My new TV's picture is great, but its sound is awful. How do I fix it?
A: As TV frames have shrunk, so has the space available for speakers, resulting in muddled audio. But a sound bar like the Vizio 54-inch S5430W-C2 ($300; vizio.com) can bring out the best in an HDTV's digital audio. This self-contained three-channel cabinet renders crystal-clear dialogue and produces deep, cinematic bass without requiring a separate subwoofer. Since it has seven inputs, you're able to connect everything from the cable box to Apple TV to a Bluetooth receiver, so the bar can double as a stereo, too.
