It's disguised as a center channel speaker. Actually, it's an anchor. Introducing the remarkably affordable SP-C21 Center Channel Speaker from Pioneer. Watch any movie on a home theater system, and the center channel speaker is where 50% of the soundtrack comes from, including the majority of the dialogue. It keeps the sound anchored to the action on-screen. The new Pioneer SP-C21 speaker does the job in stunning fashion utilizing, among other things, dual woofers in a full-sized cabinet for enhanced vocal performance. If you want your entertainment as real as it gets, the SP-C21 is one of the most important speakers you can own.
