The center channel is the most important speaker in any home theater. The Polk Audio Reserve R400 uses the latest flagship Polk transducer matrix to provide clean, clear, and articulate dialogues no matter where you sit. The distinctive Pinnacle Ring Radiator tweeter shape directs high-frequency sound propagation around the room, expanding the optimal listening zone and allowing you to freely enjoy music and movies from any seat. The innovative turbine design significantly increases cone stiffness without adding mass. This innovation enables the low-frequency driver to move with increased accuracy and speed, providing improved sound resolution and allowing you to experience an exhilarating level of detail in music and movies.
Certified Hi-Res, this tweeter is designed for listening to modern music, as well as multichannel 3D audio present in movie soundtracks, sports broadcasts, and video games.
Polk developed this woofer specifically for flagship products to provide natural reproduction of the mid-range, which human ears are particularly sensitive to. The woofer's core is made of Polk's proprietary foam polymer, and the special asymmetrical geometry significantly increases stiffness and damping without adding mass. You will hear every detail and feel the smooth, detailed mid-range and light bass.
The newly patented X-Port phase inverter from Polk includes an Eigentone (ETF) filter to ensure distortion-free and smooth bass. It consists of a set of closed tube absorbers, specially tuned to capture and eliminate traditional speaker distortions. X-Port guarantees that the upper bass and mid-range are free from port and cabinet resonances for smooth and detailed sound.
