Polk Audio® RCi Series 5.25" Matte White In-Wall Speaker

At a Glance

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.

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.

Cone Material

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

Surround Material

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

Aimable Tweeters

Aimable swivel tweeters for greater accuracy and more realistic imaging.

Dynamic Balance®

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

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

Paintable Grilles

Paintable grilles let you build them in, and then forget all about them; RCi Series speakers practically disappear into any room.

Timbre Matched

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.

Moisture-Safe Design

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.)
