CMX AUDIO CSK-66E 6″ Ceiling Speaker (1.5-3-6W) 100V

• Easy one-cut, drop-in installation puts built-in audio within reach, with Perfect Fit templates, a precision flange, and (available) pre-construction brackets.


• RCi speakers utilize the "virtual enclosure" of your in-wall and in-ceiling space to enhance their bass response and smooth low frequency blending with the midrange.


• Lightweight and stiff blue polymer cones deliver excellent damping and bass response.


• Durable, computer-modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances for a lifetime of reliable sound.


• Aimable swivel tweeters for greater accuracy and more realistic imaging. (All models except RC6s.).


• Rustproof stainless steel hardware, durable butyl rubber surrounds and powder coated aluminum (in-ceiling) & painted steel (in-wall) grilles make RCi Series speakers suitable for high moisture areas like bathrooms or even under eaves of an enclosed porch. (RCi series are not suitable for exposed outdoor use).


• RCi speakers have paintable grilles and practically disappear into any room.


• RCi Series speakers are timbre-matched to other Polk speakers to insure utterly seamless blending from speaker to speaker in systems that combine traditional and built-in speakers.
