Know before you buy
The 'RD' stands for reduced depth. This model is specifically engineered for installations where ceiling cavity space is limited, measuring just 3.6 inches deep behind the mounting surface.
Yes. The tweeter housing pivots, allowing you to aim the high-frequency output toward your listening area. Additionally, a three-position EQ switch on the front allows you to fine-tune the treble response to suit your room's acoustics.
While the speaker can be installed without one, using the compatible BB6W or BB125C back box is recommended to ensure consistent sound quality and to protect the driver from debris in the ceiling cavity.
The CCM663RD uses the QuickDogs™ spring-clamp mounting system, which is designed for a simple, tool-free, plug-and-play installation. You will only need to cut the 8-inch diameter hole and connect your speaker wire.
These speakers are compatible with amplifiers rated between 25 and 100 watts per channel. This range provides plenty of flexibility for most home audio setups.
With a frequency range starting at 35Hz, these speakers offer impressive low-end performance for their size. However, for a full-scale home theater experience, they are best paired with a dedicated subwoofer to handle the deepest cinematic frequencies.
