Brand New PROFICIENT C875S Signature Ceiling LCR Speaker with 8" Kevlar Woofer and 1" Pivoting Aluminum Tweeter - 175 W RMS - Part # C875S (Replaces Proficient C871 Ceiling LCR Speaker) - 10 Year Warranty

One LCR ceiling speaker with woofer and tweeter bridge fixed at a 15˚ angle. 8" Kevlar woofer and 1" pivoting aluminum dome tweeter, ±3dB bass & treble contour switches and 175 watt power handling.

The C875s proves you can get great home theater sound from a system that’s hidden entirely in the ceiling. Its woofer and tweeter are angled 15 degrees, so you can mount the C875s directly above the TV screen yet point it at the listeners. The 8-inch Kevlar woofer pumps out powerful, punchy bass.

Completely hidden, utterly overwhelming. Because the C875s’s woofer and tweeter are angled 15 degrees, they direct sound away from the TV screen and toward the listener. You get sonic imaging that’s close to what you hear from a conventional in-wall or freestanding speaker system, but you won’t see any speakers unless you look up. Plus you can pivot the tweeter to fine-tune the directionality. The high-quality 8-inch Kevlar woofer and 1-inch aluminum tweeter are similar to the units found in many high-end freestanding speakers. You probably won’t need to tweak the sound, but if you do, bass and treble tones switches are hidden behind the grille. Super-high sensitivity of 92 dB lets the C875s put out impressive volume with only 175 watts of power! Includes Thin-Bezel Grilles held by Neo Magnets.
