Bowers & Wilkins: CCM683 High Performance In-Ceiling Speaker...

...shares most of the high-performance features of the CCM682, but has a slightly lower maximum amp power of 130W. Like the CCM682, this speaker comes with a 200mm (8in) Kevlar cone bass/midrange driver with a rigid die-cast chassis, a Nautilus swirl-loaded aluminium dome tweeter that pivots for adjustable off-axis treble response, and a three-position EQ switch. The construction of this high-performance 8 inch in-ceiling speaker ensures clean and fast bass with excellent off-axis response.
