The Flagship Center Channel

Polk’s LSi M 706c is more than capable of handling the heavy lifting required of a center channel speaker in a high-performance home theater system. It delivers the kind of effortlessly wide, deep soundstage and realistic imaging that puts you in the middle of the on-screen action.

Polk?s exclusive dynamic sonic engine design optimizes the mid-range driver and the ring radiator tweeter in separate interior chambers for improved transient response, superior imaging and greater horizontal off-axis response.
