Put this Flagship Center Speaker Center Stage!
Big screen TV needs big sound, so make CSi A6 the center piece in your theater system. Its massive dual 6.5" midbass drivers will dish out explosive sound. It's best paired with the larger tower or bookshelf speakers.

Borrowing advanced features such as Cascade Tapered Crososver network from the LSi series, dialogue and speech come through crisp and clear while still having the authority for high impact special effects.

A unique angled top allows the speaker to inverted- so you can place the speaker below your TV and still enjoy great sound.

Because of the depth- CSi A6 includes a unique kickstand assembly that provides rear support to many projection TVs (will not work with plasmas or other TVs with completely flat rears).
