Bowers and Wilkins CCM-817 Brochure

CCM 817

See nothing, hear everything

The effort we put into speaker research is not just intended to benefit high-end hi-fi products but potentially to be applied

anywhere that high quality audio is needed. By combining a woven Kevlar® cone 180mm (7 in) bass/midrange driver with a

Nautilus™ tube-loaded, offset 25mm aluminium dome tweeter, the CCM 817 demonstrates this principle perfectly. The audible

results are startling. The CCM 817 achieves a level of sound quality previously unknown for a ceiling speaker and, if mounted

appropriately, capable rivalling that of conventionally located hi-fi speakers. For a custom install product however, the whole

package, not just the sound quality, is vital and the CCM 817 combines its extraordinary performance with an integrated tilt

chassis that enables orientation with the listening position and simple, effective swing out dog fixings.
