Stereo doesn’t get any simpler. The Proficient® Audio C625TT gives you stereo sound where mounting 2 speakers is impractical, such as in a hallway or bathroom. Its 6-1/2". polypropylene woofer has dual voice coils so it can reproduce left and right stereo channels. Dual 1/2". hard dome tweeters handle the high frequencies. Careful tuning from our team of devoted audio enthusiast/engineers makes the C625TT a sweet-sounding little speaker. You can use the C625TT with any amplifier, thanks to its high 92-dB sensitivity. A typical speaker requires 3x as much power. It’s easy to install, too, thanks to a sturdy dogleg mounting system. All of our 6-1/2". ceiling speakers use the same mounting template so you never have to worry about cutting the wrong size hole. The speaker comes with a thin-bezel grille held by neo magnets.
