Know before you buy
Yes. The CCM 684 features a pivoting tweeter and a three-position EQ switch, both of which allow you to fine-tune the high-frequency output to better suit your room's layout and seating position.
You will need a minimum of 5.2 inches of clearance behind your ceiling surface to accommodate the speaker depth.
These speakers are designed to work with amplifiers providing between 25 and 130 watts per channel. This range makes them compatible with most standard home theater receivers.
The CCM 684 uses the QuickDogs mounting system, which is designed for a simple, tool-free installation. Once you have cut the required 9.8-inch diameter hole, the spring-loaded clamps secure the speaker firmly into place.
While the speaker can be installed without one, using the optional 6C back box can help provide a more consistent acoustic environment and prevent sound from leaking into other rooms.
The woven glass fiber material is chosen for its rigidity and lightweight properties, which help the speaker produce clear, accurate midrange and bass frequencies with minimal distortion.
