Polk Audio CS245 Center Channel Speaker – 19lbs!

Impressive Polk Audio CS245 Center Channel Speaker – 19lbs! Black Finish

The Polk Audio CS245 is a classic, shielded center channel designed to deliver clear, intelligible dialogue and a solid front soundstage in home theater systems. This example is in very good condition, finished in black with a clean, understated look that pairs well with many Polk towers and bookshelves from the same era.

Behind the grille, the CS245 uses a proven 3‑driver layout with dual 5¼” Dynamic Balance mid/bass drivers flanking a 1″ Dynamic Balance dome tweeter, all video‑shielded for flexibility in placement near displays. The carefully voiced crossover uses cascaded second‑order filters to keep the midrange open and natural, so voices sound anchored, articulate, and easy to follow even at lower volumes.

With an 8 ohm impedance, 90 dB efficiency, and recommended amplification from 10–180 watts, the CS245 is an easy load for most AV receivers while still capable of handling dynamic movie soundtracks. Overall frequency response of 52–26 kHz (55–25 kHz within ±3 dB) ensures full coverage of the dialogue band, handing off deep bass to your mains or subwoofer where appropriate. 5‑way binding posts on the rear accept bare wire, spades, or banana plugs for flexible hookup.
