- Do I need an amplifier for the RC85i?
- Yes. These are passive speakers, so you need a stereo amplifier or AV receiver rated for 8 ohms. There is no built-in amplification or wireless streaming.
- Can the RC85i be used without a subwoofer?
- For music and most TV watching, yes. Its response reaches down to 50 Hz, which covers most content, but movie soundtracks and bass-heavy music will want a subwoofer.
- How many speakers come in the box?
- One box contains a pair, so you get two speakers and two grilles. That covers one stereo zone or one pair of surround channels.
- Can I paint the grilles?
- Yes. The white grilles are paintable, so you can match them to your wall. Remove them before painting and use light coats so the perforations stay open.
- Is the RC85i good for surround sound?
- It works well as side or rear channels in a surround setup, and Polk does not list it as suited for height or Atmos channels. Use it at ear level or slightly above.
- What size hole does it need?
- It is built around an 8-inch woofer and mounts in a standard in-wall cutout with clamp tabs. Check Polk's cutout dimensions for your wall before cutting.
- Where is the Polk Audio RC85i cheapest?
- At PARTS EXPRESS, for $299.00, as of our latest check.
