Make it go anywhere, do anything, and sound great. These are the demands we make upon our loudspeaker engineers. When they rise to the occasion we get a speaker like the compact, slim-profile RC55i. Small enough to fit in places larger speakers leave behind, durable enough to push the limits of possible locations into bathrooms and kitchens, the RC55i makes a great stealth surround speaker or alternate-zone extension speaker. Lush performance, with accurate details and real musicality, are the surprise of this innovative built-in design.

  • 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
  • Aim able 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) and 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

Rated 5 out of 5 by 5 reviewers.
Rated 5 out of 5 by Across the board... an excellent speaker. I have years of customer install experience in in-wall systems and have to say this model takes the cake. I am very impressed with the dynamic range of the RC55i. Even after the third customer installtion of the RC55i, I find myself wanting to sit down and really listen again to these great sounding speakers. That's something I rarely do. February 20, 2004
Rated 5 out of 5 by I made a lot of comparisons on in wall speakers and for the money and performance against other speakers in the stores the POLK speakers were the best deal. After installing them in my home I was sure my decision was the correct one. I couldn't be happier. December 2, 2005
Rated 5 out of 5 by OK...my house got flooded and before we put the drywall back on we strung speaker wire everywhere. I installed a pair of the RC55i speakers and was blown away. We get no sound distortion at all when we crank the sound. A great buy! December 3, 2004
