Description
- C825TT Ceiling Speaker
- A stiff graphite-cone woofer makes the C825TT one of the world’s best-sounding single-point stereo speakers. Because it reproduces both left and right channels of stereo sound, one C825TT can replace two conventional stereo speakers. It’s an ideal choice for places where you don’t have the space or need for two speakers.1
- Description
- Superb stereo sound made simple. With the C825TT in-ceiling speakers, you get truly great stereo sound even in tight spaces. It uses a dual-voice-coil 8-inch woofer with the same graphite cone material found in many of our better in-wall and in-ceiling speakers. The stiffness of the graphite gives you much less distortion, extremely clear sound and a deep bass response down to 28 Hz. The C825TT’s low-distortion 1-inch aluminum tweeters pivot so you can adjust the stereo effect. Power handling of 150 watts means the C825TT can really crank out the sound for parties, while its high sensitivity of 92 dB means it needs just one-third the power of a typical speaker. Tone switches let you boost bass and/or treble by 3 dB. Includes Thin-Bezel Grilles held by Neo Magnets.1
