DESC: The CM800SI is a unique ceiling mount speaker that solves one of the greatest audio installation challenges how to get high quality stereo sound out of a single speaker. The CM800SI Stereo Input Loudspeaker utilizes a 8inches dual voice coil woofer and two 3/4inches ultra-wide dispersion tweeters. Both tweeters are housed in stereo imaging faceplate which delivers both left and right channels. This speaker is ideal for any location where high quality sound is desired but two speakers just aren't practical. Typical applications include hallways, walk-in closets, laundry rooms, alcoves, and foyers. Even bathroom shower installations are possible due to the CM800SI's moisture-resistant construction. Additional features includes all brass and stainless steel hardware, MicroPerf rustproof aluminum grilles, and a quick and easy flip-tab dog mounting system.
