In wall outdoor covered use.Replaced some older in wall outdoor speakers. Definitely an upgrade and sound great. We’ll have to see how they handle Ohio winters.

RC85i - Get them! Excellent sound!I just added RC85i to home theater room. Wow! The RC85i give us the true surround sounds feeling of emersion into the shows and movies we're watching. I've already jumped out of my seat a couple of times with the excellent sounds I'm receiving. I"ve got it RC85i as surround back speakers in the walls paired with an AVR-X2700h. all of it fabulous!
Some websites are saying the RC85i is suitable for steam shower use, bower there are no details regarding this in the description. Please advise.

Hello, these speakers are not meant to be in any humid or steamy environment. You can take a look at our Marine speakers that are suited for humid environments.

Planning to buy the RC85I In-Wall speakers for the basement home theater setup. How do I know if these would suffice my need or if I need to add the in-ceiling speakers as well? Is there a guide for coverage area etc.?
Asked by: Smusic
Hello, the addition of In-Ceiling speakers will depend on the speaker setup you desire. In-Wall and In-Ceiling speakers will create a great Atmos speaker setup. I have attached a link providing several speaker configuration options. https://www.dolby.com/about/support/guide/speaker-setup-guides/

What the Minimum and recomended Cabinet Volume for RC85i?
Asked by: Marcio Usai
Hello, all of our In-Wall/In-Ceiling speakers are Infinite Baffle designs. No back box enclosures are recommended. If an enclosure is necessary, the sealed enclosure volume should be 1.2 cubic feet. This does include driver displacement. We recommend installing 1/2 to 3/4's of a pound of Dacron to dampen the enclosure.

Application: Home theater with a pair of RC85i front in wall cavity. We are about to spray foam insulation in walls. Should I leave the wall bays (8'x14.5") with the speakers empty of the spray foam? RC80i Rear speakers are mounted in common ceiling.
Asked by: Anthony J
Hello, it is best to leave the stud bays open behind the speakers. The RC85i speakers are designed to be installed in free air or infinite baffle, so you don't want to reduce the back volume. A smaller enclosure volume will result in a leaner bass and midrange response.

Will back boxes improve RC85i midrange tightness or any other audio aspect when mounted in a ceiling with open attic above? If so, enclosure volume; 1 cubic foot? Other?
Asked by: AlanC
Hello, The Polk Audio RC85i speakers are not designed to be enclosed. They are a free air or infinite baffle design. Due to their design, it is not practical to use Back Boxes.
