Bowers & Wilkins CCM663 RD Performance Series 6" In-Ceiling Speaker (Each)
RD stands for Reduced Depth – so this speaker will fit into tighter spaces than the standard CCM663. A shallower cone and a redesign of the easy-fit QuickDogs™ frame reduce depth to a more usable 92mm, while retaining everything that makes the CCM663 such a great in-ceiling speaker.

The Bowers & Wilkins CCM663 RD is a reduced-depth version of the CCM663 in-ceiling speaker, purpose-built for installations where a standard-depth speaker won't fit — tight joist spacing, shallow ceilings, or retrofits into existing construction. It cuts installation depth to just 92mm through a shallower cone design, without giving up the same driver technology used elsewhere in the Performance in-ceiling range: a Nautilus swirl-loaded aluminum dome tweeter paired with a 6-inch blue Aramid Fibre bass/midrange cone. A redesigned QuickDogs mounting frame makes fitting into the ceiling faster and more secure than a standard installation. It ships in a white finish for a clean, low-profile ceiling appearance. Detailed frequency response, sensitivity, impedance, and recommended amplifier power aren't listed on the product page, so those specs should be confirmed with a dealer before pairing it with an amplifier — but the reduced-depth form factor makes it the practical choice for anyone whose ceiling cavity can't accommodate the standard CCM663.
Q What is the Bowers & Wilkins CCM663 RD and what is it used for?
It's a two-way, reduced-depth in-ceiling speaker with a shallower cone and redesigned frame, reducing installation depth to 92mm — designed for space-constrained ceilings where the standard CCM663 won't fit.

A 25mm (1") Nautilus swirl-loaded aluminum dome tweeter and a 150mm (6") blue Aramid Fiber cone bass/midrange driver.

It uses the easy-fit QuickDogs frame system, with a reduced installation depth of 92mm.
Q What finish is it available in?
White.
Q What are its frequency response, power handling, and full dimensions?
