The RCi series lets you enjoy great Polk performance without losing valuable floor space to bulky speakers. The RC55i pairs a 5-1/4" Dynamic Balance woofer with a 3/4" soft dome Dynamic Balance tweeter to deliver powerful sound that's perfect for handling music and movie soundtracks.

The swivel-mounted tweeters let you direct the high frequencies to fine-tune the best possible sound for your favorite listening positions. And Polk's Infinite Baffle Tuning takes advantage of the virtual enclosure of in-wall space for superior bass response. Voice-matched to Polk RTi speakers, an RC55i pair makes a great set of surround speakers in a complete Polk home theatre system.

The rotating-cam design makes installation easy — once you've prepared the opening in your drywall and run in-wall-rated wiring from your receiver, you can secure this flush-mount speaker with a few turns of a screwdriver. And you can paint the white matte grilles to match any decor.
