Compact Audiophile In-Wall

Measuring only 11x7 9/16-inch with an amazing 2 1/2-inch total depth, this compact in-wall speaker fits practically anywhere. Got an unused nook or a blank space on the wall? Why not put a speaker there?

RC55i Features:

Easy one-cut, drop-in installation puts built-in audio within reach, with Perfect Fit templates, a precision flange, and (available) pre-construction brackets; achieve secure, vibration-free efficiency with a simple turn of the patented Rotating Cam system.

With infinite baffle tuning, 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.)

Polk’s proprietary, patented Dynamic Balance® technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.

Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.

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, transitional spaces or even under eaves or in the ceiling of an enclosed porch. (RCi series are not suitable for exposed outdoor use. For outdoor speaker fun, use our Atrium® Series.)

Paintable grilles let you build them in, and then forget all about them; RCi Series speakers 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.

All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.
