Know before you buy
The CWM8.5D is designed to work with amplifiers providing up to 120W of power. Its 89dB sensitivity makes it relatively efficient, but a high-quality amplifier will ensure you get the best performance from the Diamond Dome tweeter and Continuum cone driver.
While the CWM8.5D is designed for in-wall mounting, it is highly recommended to use a dedicated back box to ensure optimal acoustic performance and consistent bass response. Check with your installer to ensure your wall cavity is properly prepared for this high-performance unit.
The Diamond Dome tweeter is exceptionally stiff and lightweight, which allows it to reproduce high frequencies with incredible clarity and minimal distortion. This technology helps the speaker deliver a more detailed and accurate soundstage compared to standard metal or fabric domes.
Yes, the CWM8.5D is an excellent choice for high-end home theater systems. Its wide frequency response and precise imaging make it ideal for use as front, center, or surround channels in a discreet, minimalist setup.
To install the CWM8.5D, you will need a cut-out measuring 395mm (15.5in) in height and 231mm (9.1in) in width. Please ensure you have sufficient depth behind the wall to accommodate the speaker's internal components.
The anti-resonance plug is located in the center of the 7-inch Continuum cone driver. It works to dampen unwanted vibrations and cone breakup, resulting in cleaner, more resonant bass and clearer midrange performance.
