Bowers and Wilkins CCM7.5 In-Ceiling Loudspeaker – Part of B&W’s CI700 series of architectural speakers, the CCM7.5 features a 6-inch Kevlar midrange driver mounted into a die-cast chassis, and a Nautilus tube-loaded 1-inch soft dome tweeter. The 8-ohm speaker can be used in a variety of ways by integrators, such as distributed audio in addition to home theater, and B&W says the 88dB-sensitive speaker produces a frequency response of 56Hz to 28kHz. bowers-wilkins.com
