Polk Audio RC55i
Our take on the Polk Audio RC55i by Crutchfield's Kramer Crane
Good things come in small packages
Our customers have been using Polk Audio's RC55i in-wall speakers for movies and music for years — and their glowing reviews are telling. These compact speakers provide clear, accurate sound, and are an ideal choice for small- to medium-sized rooms. Want to make them totally disappear? Paintable grilles let you easily match them to your décor.
Versatile entertainment options
The value-packed RC55is work great as the left and right front or surround channels of an in-wall home theater. You can also use a pair of these with your favorite amp for a music system with minimum visual clutter. Team them up with a powered subwoofer for a rockin' 2.1 system.
Here's a tip I learned when installing my Polk in-wall speakers. If you're placing the RC55is six feet or higher on your wall, turn them upside down so that the tweeter is at the bottom. Then, aim the tweeter towards your seat. You'll get better high-frequency detail since the tweeter is closer to ear level.
If this is a do-it-yourself installation, check out our guide to installing in-ceiling speakers, along with our selection of in-wall speaker wire. Optional pre-construction brackets are recommended for new construction. Free lifetime technical support is provided with every Crutchfield purchase.

Features and Specs
|Quantity in Package||Pair|
|Cutout Size||6.1875 x 9.625|
|Power Range (Watts)||20-100|
|Connector Type||Spring clip|
Dynamic Balance Technology: Dynamic Balance drivers are used for wide, smooth response and low distortion.
Woofers: Each speaker features a 5-1/4" Dynamic Balance, mineral-filled polypropylene woofer for clean midrange and deep, accurate bass. For a smoother response and improved durability, each woofer uses a rubber surround.
Tweeters: Each speaker uses a 3/4" Dynamic Balance, metalized soft dome tweeter in a ball-and-socket swivel mount. The aimable tweeters give you direct high-frequency control, resulting in excellent imaging even for off-axis listening positions.
Infinite Baffle Tuning: Infinite Baffle Tuning uses the virtual enclosure of in-wall space for superior bass response.
Moisture-resistant: Durable, moisture-resistant materials allow you to install the speakers in bathrooms, kitchens, even under the eaves of an enclosed porch. (The speaker is not recommended for exposed outdoor use.)
Installation: Each speaker requires a cutout 6.1875" wide and 9.625" high with a mounting depth of 2.012". Once the holes are cut, each speaker can be dropped in and the Rotating Cams can be tightened, allowing you to secure each speaker to the drywall without any extra assembly (the Rotating Cams protrude out 0.625" from the cutout opening). If you will not be mounting these speakers in drywall, make sure the wall or ceiling material can safely support the weight of the speakers before installation; each speaker weighs approximately 3.5 pounds.
Paintable: The grille and flange can be painted, allowing these speakers to match any decor.
- Overall: 67 Hz-20 kHz
- -3 dB Limit: 70 Hz-20 kHz

This is to replace two ceiling speakers for my surround sound. Polk Audio RC55i sound amazing in this configuration. [ TERI Dec 01, 2017 ]
Replacement of 20 year old in ceiling polk audio speakers we have been very happy with due to a water damage event. Erin was very helpful with the selection. [ Ken Nov 12, 2017 ]
Consistently great reviews. [ Jeff Nov 09, 2017 ]
I choose these for their power to price ratio and because they fit the needs of my new home build. [ Winston Jul 04, 2017 ]
Polk is a high quality brand yet also delivers good value. I purchased these for in wall surround speakers in a 5.1 set up as hanging satellite speakers on my rear wall was going to be obtrusive [ JOHN J Jun 05, 2017 ]
best quality at lowest price [ Bruce Apr 11, 2017 ]
I like Polk.. I needed an in wall smaller then the RC80 to fit in a narrow span between studs on one wall in my living room. I will use the RC80's in my theater for Atmos overheads. [ Cristine Hall Feb 01, 2017 ]

The grill itself is 5 7/8" x 9 3/8" [ Bill Oct 25, 2017 ]
Hey Jeff, I own a set of these speakers and they sound pretty good! I currently have them as my surround (in-wall) speakers on a 5.1 setup, but if you are using them for general purpose (watching TV, music, etc.) I will put them flanking your TV in the wall and the distance between speakers should be equal to the distance between your TV and the sitting (viewing) area approx. Good luck! [ Jose May 25, 2016 ]
If these are the only speakers I would put them on the wall with the TV as a Front left and Front Right [ Ryan May 25, 2016 ]
I have the same situation. Cut some wood blocking and put plywood on top.It became a shelf speaker on the ceiling.To me it souds much better. [ ASSEN Jan 27, 2015 ]
Sure. I think they're designed to be installed vertically, but there's no reason other than for audio perfection that they cannot be installed horizontally. [ RYAN J Jan 23, 2015 ]
I installed a pair in my ceiling as rear speakers and they work well. No reason they couldnt be installed horizontally in a wall. Radiation pattern will change but probably not a big deal [ SCOTT Jan 23, 2015 ]
Sure. If you have enough room between the studs. [ GREGORY C Jan 23, 2015 ]
Yes. I have them up & down, sideways and in the ceiling. [ WILLIAM P Jan 23, 2015 ]
Mine was new as far as I can tell. Crutchfield would have to answer for anything you get from them, of course. [ STEPHEN C Sep 23, 2014 ]
These are new [ KUAKA Sep 23, 2014 ]
New [ EDWARD W Sep 23, 2014 ]
These speakers should work well in most locations of a 7.1 system, but the best location will depend on the type of 7.1 system you are going for. Call or chat with an Advisor to discuss the set-up you are looking at, and they will be able to help determine the best speakers to fit your room and needs. [ Jeff Nov 27, 2013 ] Staff
