Our take on the Polk Audio RC55i

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's Monitor Series speakers, an RC55i pair makes a great set of surround speakers in a complete Polk home theater system.

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.

Monitor Series Timbre-matched: These speakers are timbre-matched to the Polk Audio Monitor Series for seamless, enveloping imaging when used in a home theater system.

Mounting Options

Installation: Each speaker requires a cutout 6.1875" wide and 9.625" high with a depth of 2.012" behind the drywall. 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.

Great Surround Speakers

Written By Ross, Nevada on Sunday, April 24, 2011
 
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
 
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.
