CNET editors' surround sound buying guide:
Surround sound speaker packages![]() If you're feeling surrounded by questions instead of ambient sound, you've come to the right place. We have suggestions on how to shop for everything surround, from receivers to speakers to full home-theater systems. Speaker packagesPackaged systems take the guesswork out of buying the most important part of any surround-sound system. We'll go through their component speakers and let you know what to look for. Speaker package basics:
Front-left and front-right speakers |
Center speaker | Front-left and front-right speakersYou can choose from miniature 4-inch-tall satellites or move up to hulking tower speakers. There's a size and shape for every taste. While the best small speakers can sound awfully good, they produce less bass and have loudness limitations compared to larger speakers. Full-size, 38-inch-tall or larger tower speakers frequently offer the best overall sound, though midsize 12- to 15-inch-tall bookshelf speakers may be the best compromise for sound-conscious buyers who can't accept the visual intrusion of full-size speakers.![]() Center speakerThe same logic applies to the vitally important center speaker, which is responsible for reproducing a large part of your DVD's dialogue, effects, and music. The smallest 7-inch-wide models are the least visually intrusive but most sonically compromised.Surround speakersA standard 5.1 system uses a pair of surround speakers, located to the sides of the main listening position. The newer Dolby EX/DTS ES 6.1 systems add either one or two surround speakers, centered behind the main listening position.SubwooferSubwoofers supply deeper bass than satellite speakers. Once again, cabinet and driver size play a large part in predicting bass quality and quantity. Lower-end HTIB models are called passive, meaning the receiver's amplifier powers the subwoofer. Higher-quality subwoofers are powered, as they have their own onboard power amps.Every which wayIndividual speakers come in three flavors:

Generally speaking, two-way speakers produce better sound than the one-way designs found on many entry-level HTIB systems. And three-way speakers usually sound better than two-ways. Some designs add one or more extra woofers, though multiple woofer, or midranges don't increase the "ways" of a speaker--a speaker with two woofers, one midrange, and one tweeter is still a three-way speaker. Multidriver speakers are usually pricier than speakers with fewer drivers.
