About the CCM663RD

The Bowers & Wilkins CCM663RD is a performance two-way in-ceiling speaker designed for installations where depth is limited. The 'RD' stands for Reduced Depth, achieved by a shallower cone and a redesigned QuickDogs frame, reducing the mounting depth to 92mm (3.6 inches) while maintaining excellent sound quality. It features a 150mm (6 inch) blue Aramid fiber cone bass/midrange driver delivering clean, detailed response, and a 25mm (1 inch) Nautilus swirl loaded aluminum dome tweeter that pivots for adjustable off-axis treble response. The speaker includes a three-position EQ switch to optimize sound for different installation environments. The supplied round grille is magnetic and paintable, with an optional square grille available. Recommended amplifier power is 25 to 100 watts, with a nominal impedance of 8 ohms and sensitivity around 86-88 dB. The speaker has a cut-out diameter of 202mm (8 inches), an overall frame diameter of 240mm (9.4 inches), and protrudes only 7mm (0.3 inches) from the ceiling surface. Compatible with PMK C6 pre-mount kit and BB6W or BB125C back boxes (sold separately). It is ideal for high-end in-ceiling music systems or home theater overhead channels.
