  • The exceptionally stiff and light Diamond diaphragm ensures pure, distortion-free treble. It also includes a dark Continuum FST driver for pristine midrange sound. The range's only three-way loudspeaker also benefits from using ultra-light yet exceptionally stiff low-frequency Aerofoil drivers for incredible bass performance.

3-Way Driver Design
The Bowers & Wilkins CWM7.3 S2 utilizes a three-way driver design with a 1" Carbon dome tweeter, one 4" Continuum FST cone midrange driver, and two 6" Aerofoil Profile bass woofers for full-range sound. The 1" Carbon dome tweeter delivers pinpoint imaging accuracy and detail, while the 5" Continuum FST cone midrange driver provides a natural and open midrange sound. The two 6" Aerofoil Profile bass offers to deliver deep, dynamic, and accurate bass responses.

Flow port Technology
The B&W in-wall speaker has a critically formed baffle box constructed from glass reinforced ABS, plus its integrated back box for accurate, detailed sound. It also utilizes B&W's Flowport technology with a front-firing port to create a smooth, deep, and efficient bass response from a compact in-wall loudspeaker. Its front-firing, dimpled flared port provides a natural bass response without turbulent noise or distortion.

Spring-Post Terminals
The B&W CWM7.3 S2 in-wall loudspeaker is outfitted with spring-post terminals that will accommodate bare speaker wire (up to 12AWG), pin connectors, and banana plugs (single only).

Magnetic & Paintable Grilles
The Bowers & Wilkins CWM7.3 S2 in-wall loudspeaker includes easy-to-install magnetic grilles that are also paintable. The grille protrudes 0.3125" from the wall.

In-Wall Installation
The B&W CWM7.3 S2 requires a rectangular cutout and is secured in the wall via the included mounting frame with integrated "QuickDogs" spring-loaded clamps that tighten using Phillips-head screws. The cutout will need to measure 9.9375" (w) x 28" (h) x 4.0625" (d). Make sure there is a least 0.75" of clearance around the cutout opening for the integrated "QuickDogs" clamps. The mounting clamps will accommodate 0.25" to 1.25" thick drywall. The included baffle box attaches to the top or bottom of the in-wall speaker and measures 8.5625" (w) x 18.0625" (h) x 2.5" (d). Make sure there is enough room inside the cavity of the wall for the included baffle box.

Designed for in-wall use, the B&W CWM7.3 S2 can be used as a front, center, or rear channel speaker in a home theater system. It can also be used in a 2-channel stereo application.

  • Home Theater: When used as front channels, the left and right speakers should be located on either side of the screen approximately 20" away. When used as a center channel, the speaker should be located either directly above or below the screen; or in the case of an acoustically transparent screen, directly behind the screen. As rear surround channels, the speakers should be located just behind and on either side of the listening position.
  • 2-Channel Stereo: For applications where a pair of CWM7.3 S2 speakers are to be used for conventional stereo reproduction, they should be located between 10' and 16.5' apart and at a similar distance in front of the listening area.
