Our take on the Polk Audio RC55i In-Wall Speakers

The Polk Audio RC55i is a pair of rectangular in-wall speakers built around a 5 1/4-inch driver, rated 67 Hz to 20 kHz with 90 dB sensitivity and an 8-ohm load. That sensitivity and impedance make them easy to drive from an ordinary AV receiver, and the shallow rectangular baffle fits standard stud bays. They suit surround and background channels in a living room or a whole-house audio setup where floor space is tight. Against pricier in-wall lines they give up some bass depth and output, but they are a simple, forgiving choice for filling a room with sound.

Pros
  • Easy to drive at 90 dB sensitivity and 8 ohms
  • Pair included, so one box covers a stereo or surround pair
  • Slim 9.625 x 6.25 inch rectangular footprint
  • Covers 67 Hz to 20 kHz for music and movie effects
  • Optional pre-construction brackets simplify new-build installs
Cons
  • 5 1/4-inch driver limits bass below roughly 70 Hz
  • In-wall placement fixes the listening position
  • No enclosure, so sound depends on the wall cavity
  • Modest output for large or open rooms

What reviewers say

Owners of Polk's RCi in-wall line generally describe them as clean, easy-to-install speakers that disappear into the wall and handle surround duty well. Most criticism centers on limited bass and the need for a subwoofer in a full home theater.

What people mention
  • BassCriticisedOwners say low frequencies are limited and a subwoofer is needed for movie soundtracks.
  • InstallationPraisedBuyers describe mounting in standard stud bays as quick and simple.
  • SensitivityPraisedThe 90 dB rating means ordinary receivers drive them without strain.
  • Sound qualityMixedListeners find them clean for surround and background use but not a match for dedicated floorstanding speakers.
  • Wall cavityMixedOwners note the sound depends on what is behind the wall, so results vary by room.

Questions and answers

Do I need an amplifier to use the RC55i?
Yes. They are passive speakers, so they need an AV receiver or amplifier. The 8-ohm load and 90 dB sensitivity mean most receivers can drive them.
Do they come as a pair?
Yes, the box contains two speakers, enough for a stereo pair or one surround channel pair.
Will they produce deep bass?
No. Response reaches down to about 67 Hz, so a subwoofer is worth adding for movies or bass-heavy music.
Can I use them in a ceiling?
They are designed for in-wall mounting, but Polk publishes an in-ceiling installation guide for its RCi series, so ceiling use is possible with the right cutout.
What size hole do they need?
The outer baffle measures 9.625 by 6.25 inches. The cutout is smaller; check Polk's RCi manual for the exact template before cutting.
Are pre-construction brackets included?
No. The PB 55 pre-construction brackets are optional accessories, useful when the wall is still open during a build.
