Polk Audio Rc85i Installation Instructions
Home audio enthusiasts and DIYers are increasingly turning to in-wall speakers for streamlined sound systems. The Polk Audio RC85i, known for its balanced sound and ease of installation, remains a popular choice. While installation is generally straightforward, understanding the recommended procedures is crucial for optimal performance and longevity.
This article provides a detailed guide, gleaned from Polk Audio's official documentation and user experiences, on installing the Polk Audio RC85i in-wall speakers. Proper installation ensures optimal audio quality and prevents potential damage to both the speakers and the surrounding wall structure.
Preparing for Installation
Before starting, gather the necessary tools and materials. This includes a pencil, drywall saw, level, wire stripper, wire connectors, and speaker wire. Ensure the speaker wire is of appropriate gauge, typically 16- or 14-gauge, depending on the length of the run.
Safety First: Always turn off the power to the circuit you'll be working on to prevent electrical shock. Use a non-contact voltage tester to confirm the power is off before proceeding.
Carefully unpack the RC85i speakers and inspect them for any damage. Consult the user manual, which can be downloaded from the Polk Audio website, for detailed specifications and safety precautions.
Choosing the Location
Speaker placement significantly impacts sound quality. Consider the room's acoustics and intended use when selecting locations for the RC85i speakers. Polk Audio recommends placing speakers at ear level when seated for optimal stereo imaging.
Avoid placing speakers near corners or in areas where they might be obstructed by furniture. Check behind the wall for any obstructions, such as pipes, wiring, or studs, before cutting.
Use a stud finder to locate studs and mark their positions on the wall. This will help you avoid cutting into a stud when creating the speaker cutout.
Installation Steps
Using the provided template, trace the outline of the speaker onto the wall. Ensure the template is level before marking the wall. Double-check measurements to avoid costly mistakes.
Carefully cut along the traced outline using a drywall saw. Start slowly and maintain a steady hand to avoid damaging the wall. Use a vacuum cleaner to remove dust and debris.
Run the speaker wire from the amplifier to the speaker location. Leave enough slack for easy connection and future adjustments. Secure the wire to the wall studs using staples or cable ties to prevent it from dangling.
Connect the speaker wire to the RC85i speaker terminals, ensuring correct polarity. The positive (+) terminal on the amplifier should be connected to the positive (+) terminal on the speaker, and the negative (-) terminal should be connected to the negative (-) terminal. Incorrect polarity can result in poor sound quality.
Insert the RC85i speaker into the cutout. Secure the speaker by tightening the mounting screws on the front baffle. These screws activate the rotating cams that clamp the speaker to the wall.
Adjust the tweeter for optimal sound dispersion. The Polk Audio RC85i features a pivoting tweeter that can be aimed towards the listening area for improved clarity.
Final Touches and Testing
Once the speakers are securely mounted, perform a final visual inspection. Ensure all wires are properly connected and that the speaker is flush with the wall.
Turn the power back on and test the speakers. Play a variety of music to ensure they are functioning correctly. Listen for any distortion or anomalies in the sound.
Troubleshooting: If you experience any problems, consult the Polk Audio user manual or contact their customer support for assistance. Common issues include incorrect wiring, loose connections, or amplifier settings.
By following these detailed instructions, users can successfully install Polk Audio RC85i in-wall speakers and enjoy enhanced audio in their homes. Proper installation is key to maximizing the speakers' performance and ensuring a seamless integration into any home audio system.
