All dialogue comes from this speaker, which means there is no more important speaker in the surround sound system than the center channel. It is the speaker that holds the rest of the system together. The 4th generation of the Klipsch Reference series enhances the tweeter with details and ensures ideal airflow for the lowest frequencies through the rear Tractrix port with a dual bass reflex output. The surface is framed with a scratch-resistant, satin-finished enclosure. The aluminum stand feet not only provide a modern design but also minimize resonance with the floor contact more effectively than MDF or ABS plastic. Faster, denser, and deeper frequencies with more detail are decoupled.
