Surround Sound Speakers
Most DVD soundtracks are recorded with either Dolby Digital 5.1 or DTS (Digital Theater Systems) 5.1. Don't let your eyes glaze over at the sight of that number. The "5" refers to five channels, one for each speaker in your surround sound system, and the "1" refers to the subwoofer. This means you don't need more than five speakers and one subwoofer to get that three-dimensional sound experience. In fact, instead of buying seven speakers, buy five and spend the extra money on quality. Your ears will thank you.
