The Polk Audio RC65i is easy to install, requiring only that you cut a hole, feed the wires through, and simply drop the speaker in where it is held in place by rotating cams that safely secure the speaker with no extra assembly or mess. Once installed, the paintable grille and flange allows this in-wall speaker to virtually disappear in the room.
The Polk Audio RC65i utilizes a 6.5-inch dynamic-balance, mineral filled polymer-composite cone with a rubber surround that outlasts cheaper foam surrounds, as well as a 0.75-inch dynamic-balance, metalized soft dome tweeter with a swivel mount. The swivel-mounted tweeter is aimable for direct high frequency control that ensures spacious imaging with amazing clarity, and well-balanced sound in any listening position, even off-axis listening positions, rather than in just a small sweet spot. Constructed of durable, moisture resistant materials, the Polk Audio RC65i is safe for use in bathrooms, kitchens, saunas, or even under outdoor eaves, and features a wide-dispersion design for even sound-coverage throughout even large rooms. The Polk Audio RC65i also features infinite baffle tuning which uses the virtual enclosure of in-wall space for superior bass response, and is timbre-matched to the Polk Audio Monitor Series for seamless, enveloping imaging when used in a home theater system.
I purchased a pair of Polk Audio RC65i in-walls for a pool table/game room area I am building in the basement. My receiver is an Onkyo 805 7.1 home theater system and these will serve as stereo/audio part for only that room. I have never owned Polk Audio RC65i or in wall speakers for that matter and listened to them at the big box store before purchasing Polk Audio RC65i through Amazon. I was really impressed at the audio quality. I also didn't want floor standing speakers, but didn't want to sacrifice audio quality either so these speakers filled the bill.
No back boxes are necessary, the Polk Audio RC65i is designed as an "infinite
baffle" type and only requires that the front and rear moving sound wave
are isolated from each other. Polk recommends to maximize the sound quality, you place a modest amount of a sound absorbing material, such as Polyfil (a synthetic cotton-like material found at craft/fabric stores) inside the cavity before installing the Polk Audio RC65i. Supposedly, this will absorb the rear moving sound wave and reduce mid range coloration. I think insulation also works just as well. I haven't done this yet and they still sound excellent! Oh, I love Polk Audio RC65i.
