The Bowers & Wilkins CCM684 is a high-performance, two-way in-ceiling speaker designed as a simple and cost-effective route to high-quality distributed audio in homes and custom installations. It pairs a 25mm (1 in) soft-dome tweeter with a 200mm (8 in) woven glass fibre bass/midrange driver to deliver full-scale, detailed sound from a discreet ceiling-mounted enclosure. The tweeter is mounted on an adjustable offset mount, allowing you to angle the high frequencies toward the listening area for better imaging and clarity across the room. A three-position EQ/tilt switch helps optimize tonal balance and off-axis response to suit different installation positions or room acoustics. With its low-profile round grille (paintable to match the ceiling) and quick-fit mounting system, the CCM684 installs easily and blends unobtrusively into most decors, making it suitable for background music systems, multi-room audio, or as part of a Bowers & Wilkins home theater ceiling array.
