The Polk Audio CS2 center channel speaker is designed to deliver clear, spacious, and natural sound with a high-efficiency design that works well even with modestly powered amplifiers. It features dual 6.5" Bi-Laminate composite dynamic balance drivers that are lightweight and stiff for excellent bass and midrange performance, paired with a 1" fabric/polymer composite dynamic balance dome tweeter with a powerful neodymium magnet for detailed high frequencies. The enclosure is made of non-resonant all-MDF with 1.75" thick baffles to ensure cleaner, clearer sound. The speaker includes a critically tuned flared port to minimize port noise and extend low-frequency response. It has a bass-reflex design, video shielding, and five-way binding post connectors for secure hook-up. The cabinet is reversible to allow aiming the sound upward when placed under a video monitor. Available finishes include black oak vinyl and cherry with titanium faces. Dimensions are approximately 21-1/4" wide, 7-3/4" high, and 11-1/8" deep, weighing about 17 to 20 pounds. It handles amplifier power from 20 to 175 watts, has an 8-ohm impedance, 90 dB sensitivity, and a frequency response of 60 Hz to 24 kHz (-3 dB). The product comes with a 5-year warranty and is no longer in current production but remains popular in the used market.
