Our take on the Polk Audio RC55i

by Barry Montgomery

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. The R55i is voice-matched to other Polk speakers, so you can use a pair as your surround speakers in a home theater system that includes more traditional freestanding speakers for the front channels.

The rotating-cam design makes installation easy — once you've prepared the opening in your drywall and run UL-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.

An optional in-wall bracket is recommended for installing the RC55i in a home with new construction.

    Features

    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, saunas, even under outdoor eaves.

    Mounting Options

    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. 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.

    Polk RC55i

    Written By Mark, State College Pa on Monday, May 06, 2013
    Crutchfield Customer Review (What's this?)
     
    I purchased these speakers for my media room. The room is not large (14x16). They were easy to install in the walls. You must cut the holes exactly to the template size. They fit snug and are easy to tighten in place. I painted the grills and plate to match the wall color. They look and sound Great!
    Pros:
    Easy to install. Sound great. Look great.
    Cons:
    none

    Great solution for my needs

    Written By Squid628, Houston, TX on Wednesday, March 27, 2013
    Crutchfield Customer Review (What's this?)
     
    These are my first speakers for a surround system, I'm no audiophile, but I wanted something that gave me good solid sound without breaking the bank. These were easy to install, came out of the box in great condition and to my ears sound nice bright and clear. I have two used as fronts, two as satellites, and they are paired to a Polk sub and center channel. With a Denon 1913 receiver, and a samsung 7100, my movie experience is everything I could have hoped for.
    Pros:
    Well packaged, easy to install. Disappear once in the wall. Price is right.
    Cons:
    So far, none.

    Polk in walls

    Written By KirkM, Aberdeen, MD on Monday, December 03, 2012
    Crutchfield Customer Review (What's this?)
     
    For the price, you absolutely cannot beat these speakers. These are the second pair I have purchased over the years, both times for rear surrounds. They do not have much bass and their clarity is not the greatest, but for surrounds, they are more than adequate. Would get them again.
    Pros:

    These speakers arrived as promised and look great! We are building a new house and will install them very soon. We can't wait to use them. These were recommended by Crutchfield and they have never let me down before, so I anticipate they will provide excellant quality.
    Pros:
    Polk has an excellant reputation and I have other Polk speakers, These should be just as impressive.
    Cons:
    None so far.

    Awesome Speakers

    Written By Robert, Grand Rapids, MI on Monday, October 01, 2012
    Crutchfield Customer Review (What's this?)
     
    Mounting was easy. Find the studs, copy the template, cut around them, hook up the wires and insert into the wall. Look great. I painted them with a foam roller. There is a plastic insert you put over the speakers to protect them when painting. It goes where the grill is, so you can paint the speaker frame and grill separately. I put the grill in and my wife didn't like it so I pulled them out, painted the grill black with a spray can. They look even better.. Once I programmed the speakers with my Denon AVR 1912 the rear sound came out beautifully! Really like these speakers.
    Pros:
    Easy mounting. Nice looking speakers.
    Cons:
    None

    Polk Audio RC55i

    Written By Anonymous, Gilbertsville, PA on Wednesday, March 28, 2012
    Crutchfield Customer Review (What's this?)
     
    I bought these for rear surround after my wife and I decided to change our family room. I researched many brands and settled on the Polk RC55i after reading the reviews. These speaker are perfect for what I wanted them for and sound great. Can't beat the price. I have two RC85i set-up for my front speakers and when combined with my subwoofer, I was blown away by the sound. My wife was also impressed by the quality. The best part was the ease of installation. If you are able to use a drywall saw and screwdriver, you will be able to install these speakers. Running the wire could be challenging, but not impossible. The one thing I would recommend is when using the templates to cut the openings in the wall, make sure you cut a fraction over the line. I made my openings a bit on the short side. The speakers went in very snug, which i thought was good, until I tried to put the screens back on. The frames compressed a bit and made it difficult to get the screens back on. No big deal though, just shaved the drywall with a rasp and in no time had them back in the wall. I am looking forward to enjoying these speakers for many years. My next step is to get my basement set-up with the same configuration.

    Surround speakers

    Written By Dean, Mn on Wednesday, February 22, 2012
    Crutchfield Customer Review (What's this?)
     
    The speakers seems to be of very high quality for the modest price. I plan to use the speakers as rears speakers in a 5.1 setup. I have not totally setup the system yet but have hooked them up and they sounded very good. Yesterday I painted the face covers. I used a small felt roller and rolled out the paint before applying to the mesh screen. It worked great!! The key is not having a lot of paint on the roller and a light touch with the roller. Used the same roller on the face plate with the plastic covers in place. The setup in the wall worked just like the directions stated. Very happy so far.

    Great Surround Speakers

    Written By Ross, Nevada on Sunday, April 24, 2011
    Crutchfield Customer Review (What's this?)
     
    Have been using these fo about five years as surround speakers. They work
    great. Got the small ones cause I didn't need the low end but they still do a nice
    job with 5.1 concerts. Very good sound repro. Just bought two more to use as
    surround back since upgrading to 7.1 so they all match.
    Had the local paint store put some of the room paint in a spray can so they
    match the wall. They paint up real nice and come with plastic covers to cover
    the speakers while you paint the frame. Cant even tell they are there - a plus
    with the wife after telling her I was mounting two more in-wall speakers.

    Used as a center channel speaker

    Written By Frank C., Columbia, SC on Thursday, December 30, 2010
    Crutchfield Customer Review (What's this?)
     
    I wanted to go with an in wall center stage speaker but wanted to stay with the Polk
    Audio name. I searched around and could not find anything that would fit that was
    specifically a center speaker. I figured that the RC55i should work, I only needed one
    but they are sold in pairs. It was cheaper to buy a pair of RC55i's than buy 1 specific
    center stage that may or may not fit between the studs. Remember, all houses are not
    perfect. I installed the RC55i horizontally under the wall mounted TV and it sounds great
    for a center channel. Used the RC60i speakers also. See that review. The only
    complaint I have is that the speakers are advertised to have pivoting tweeters behind the
    grill. I started to aim the tweeters towards the sofas and they were so stiff and delicate
    looking that I was afraid I was going to break them off.
