Bowers & Wilkins CWM664: Reference-Class Sound Built Into the Wall
A tube-loaded Nautilus aluminium dome tweeter and a 150 mm glass fibre bass/midrange driver bring Bowers & Wilkins refinement to an in-wall speaker, reaching down to 45 Hz and up to 35 kHz. Built for Discreet Home Cinema and Multi-Room Listening
In-wall speakers should disappear visually yet still deliver depth and detail. The CWM664 uses a fibre-reinforced bass/midrange cone and a metal dome tweeter to keep voices natural and effects crisp, so the wall becomes part of the sound system rather than a limitation. What It Is
The CWM664 is a two-way in-wall loudspeaker sold individually. It combines a 25 mm Nautilus tube-loaded aluminium dome tweeter with a 150 mm (6 in) black glass fibre cone bass/midrange, and it fits a wall cut-out of 279 mm x 183 mm. Key Features – Nautilus tube-loaded aluminium tweeter: Extended, detailed treble to 35 kHz, with the Nautilus tube absorbing the tweeter's rear output for cleaner sound. – 150 mm glass fibre bass/midrange: A rigid, lightweight cone for tight, articulate bass and natural voices. – 45 Hz – 35 kHz response (-6 dB): Broad range for music and film. – 87.5 dB sensitivity, 8 Ohm nominal: Compatible with a wide range of amplifiers; 25-130 W is recommended. – Slim installation: The frame measures 315 x 221 mm, with a depth of 95 mm behind the wall surface. – Clean look: The speaker sits close to the wall and blends into the room. Why the Bowers & Wilkins CWM664 Stands Out
Many in-wall speakers sacrifice fidelity for convenience. The CWM664 is voiced by Bowers & Wilkins to sound like the company's free-standing models, with a metal dome tweeter normally found in higher-end speakers. That makes it a strong choice for stereo pairs and for left, centre and right channels in a home theatre. Perfect For – Home cinema left, centre and right channels – Music listening in living rooms and dens – Homes where speakers must stay out of sight Best Suited For
Homeowners and installers building a quality, hidden audio system. Check wall depth and the cut-out measurements first. This listing is for one speaker; order two for a stereo pair. Frequently Asked Questions
