Bigger bass, smaller price. You'll be amazed when you hear how much sound our most affordable 61/2-inch ceiling speaker puts out. Its sturdy polypropylene woofer is the same type found in many high-quality bookshelf speakers. And its 3/4-inch soft-dome tweeter sounds surprisingly sweet-no surprise when you learn it was engineered by the same team that designed our top in-wall, on-wall and bookshelf speakers. The C606's 90 dB sensitivity delivers high output even with low-powered multiroom audio amplifiers, so you can get the same volume with about half the power. The C606's forgiving 8 Ohm impedance makes it easy to drive with any amplifier. It also fits into the same cutout as all of our other 6-1/2" ceiling speakers do, so it's easy to install. Includes Thin-Bezel Grilles held by Neo Magnets.
