Polk Audio RC85i In-Wall Speakers (Pair) - 8" 2-way Premium Sound for Indoor/Outdoor Use

Q: What is the depth needed in the wall for the Polk Audio RC85i speakers?
A: The PDF spec sheet indicates that 2 3/8" is needed assuming mounted to 1/2" drywall.

Q: Do you need a subwoofer for these speakers, or do they sound okay without it?
A: These speakers have an 8" dynamic-balance woofer and a 1" tweeter, which add more depth and detail to your music. They also feature a rubber seal that drives better response and prevents moisture access, making them suitable for use in bathrooms, kitchens, saunas, and covered porches. While they can be used without a subwoofer, it is recommended for home theater setups.

Q: Can I paint these speakers with my wall color?
A: Yes, you can paint the frames and grilles to match your existing interior. The speakers come with a clear plastic insert that acts as masks for the frame. It is recommended to use sprayed paint or a small roller with several very light coats.

Q: Can these speakers be used on a concrete wall?
A: These speakers require a 1/2" or 5/8" drywall to mount effectively. If you have drywall over the top of your concrete wall, then this should work (although running speaker wiring presents its own challenge). However, installing in-ceiling speakers in a concrete wall can pose challenges due to the required opening size being larger than the drywall.

Q: What's the maximum wattage for these speakers?
A: These speakers should be used with amplifiers from 20 to 100 watts/channel.

Q: Can these be used as rear speakers? If so, what size is recommended to go with the 8" for in-wall fronts?
A: These can be used as rear speakers. It is recommended to match them with 6.5" speakers for all surround speakers, matched up to 8" front mains.

Q: How do these speakers compare to the Polk Audio RC80i for a 5.1 ceiling system in an 18'x24'x10' room for music and movies?
A: While there is no direct comparison available, the RC85i speakers have an 8" dynamic-balance woofer and a 1" tweeter for more depth and detail in music. They are also suitable for use in high moisture areas like bathrooms and kitchens.

Q: Can the RC85i speakers be removed and reinstalled after initial installation?
A: Yes, it is possible to remove and reinstall these speakers after initial installation. However, it requires a big square of drywall and some skills to close the hole.

Q: Do I need construction brackets for these speakers?
A: No, all the hardware for mounting these speakers onto drywall (plasterboard) is included in the box. No other brackets are required.
