One pair of ceiling speakers with 8" graphite woofers, 1" pivoting aluminum dome tweeters, +3dB bass and treble contour switches and 150 watt power handling. Refined sound with raw power. The graphite material used in the C801's woofer cone is far stiffer than almost any other cone material you can find. That means it produces low distortion and very clear sound. To keep up with the high-powered woofer, we gave the C801 a low-distortion aluminum tweeter. The tweeter pivots so you can direct the sound wherever you want. You can boost bass and/or treble by 3 dB using the tone switches behind the grille. A high sensitivity of 92 dB lets the C801 hit 100 dB with just 8 watts of power. With 28Hz bass extension and 150W power handling, this speaker cranks out more than enough oomph for any party anywhere! Includes Thin-Bezel Grilles held by Neo Magnets. With its ultra-stiff graphite-cone woofer, the C801 is one fantastic-sounding ceiling speaker. The big 8'' woofer pumps out awesome bass, and the pivoting tweeter delivers clear highs wherever you want them. Bass and treble boost switches hidden behind the grille let you fine-tune the sound in seconds.
