Bowers & Wilkins CCM663RD Ceiling Speaker Pair

Bowers & Wilkins CCM663RD Ceiling Speaker Pair   RD stands for Reduced Depth so this speaker will fit into tighter spaces than the standard CCM663. A Shallower cone and redesign of the QuickDogs frame reduce depth to a more usable 92mm. While retaining everything that makes the CCM663 such as a great in-ceiling speaker.
The familiar, yet discreet, dark blue Aramid Fibre cone of the bass/midrange driver delivers a stunningly clean, detailed response. Combined with the pivoting aluminium dome tweeter for adjustable off-axis treble response and three position EQ, make this one of the most versatile custom speakers around.
