Bowers & Wilkins CCM7.5. The Bowers & Wilkins CCM7.5 is the entry-level model in the CI700 in-ceiling speaker range—but it certainly doesn't compromise on performance or features. At the heart of the CCM7.5 is a 150 mm (6") blue Kevlar cone bass/midrange driver housed in a rigid die-cast chassis for reduced resonance and greater clarity.
