4.2 Mounting Instructions
- Prepare the Opening: Use the provided Perfect Fit template to mark the cutout area on your ceiling. The cutout diameter is 8.19 inches (20.8 cm). Ensure there is sufficient mounting depth of 3.94 inches (10 cm).
- Cut the Opening: Carefully cut the marked opening using an appropriate tool.
- Run Speaker Wires: Route speaker wires from your amplifier to the speaker openings. Ensure wires are rated for in-wall/in-ceiling use and meet local building codes.
- Connect Wires: Connect the speaker wires to the terminals on the back of the speaker. Observe correct polarity (+ to + and - to -).
- Insert Speaker: Gently insert the speaker into the cutout opening.
- Secure Speaker: Tighten the rotating cams with a screwdriver. These cams will pivot and clamp the speaker firmly to the ceiling, ensuring vibration-free efficiency. Do not overtighten.
- Attach Grille: Place the magnetic grille onto the speaker frame. The grille can be painted to match your ceiling before installation.

4.3 Wiring
The MC60 speakers have an impedance of 8 ohms. Connect them to an amplifier or receiver capable of handling an 8-ohm load. For optimal performance, use high-quality speaker wire of appropriate gauge for the length of the run.
5. Operation
Once installed and connected, your Polk Audio MC60 speakers are ready for use.
5.1 Adjusting the Aimable Tweeter
The 0.75-inch silk dome tweeter can be aimed to direct high-frequency sound towards your primary listening area. Gently swivel the tweeter within its mount to achieve the desired sound dispersion. This helps optimize the soundstage and detail in your music.
5.2 Audio Playback
Connect your audio source (e.g., smartphone, tablet, MP3 player, desktop, television, projector, laptop) to your amplifier/receiver. Select the appropriate input and begin playback. The MC60 speakers are designed for excellent ambient acoustic performances with extraordinary detail and natural musicality, even at low volumes.

6. Care and Maintenance
The Polk Audio MC60 speakers are built for durability and moisture resistance, requiring minimal maintenance.
- Cleaning: To clean the speaker grilles and frames, use a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners.
- Grille Painting: If you choose to paint the grilles, ensure they are clean and dry. Use a thin coat of spray paint to avoid clogging the grille perforations, which could affect sound quality.
- Moisture: While moisture-resistant, avoid direct water spray or submersion. Ensure the rubber surrounds remain intact to prevent moisture access to internal components.
7. Troubleshooting
If you encounter issues with your MC60 speakers, refer to the following common problems and solutions:
- No Sound:
- Check all cable connections from the amplifier to the speakers. Ensure polarity is correct.
- Verify the amplifier is powered on and the correct input source is selected.
- Test with another audio source or speaker if possible to isolate the problem.
- Distorted Sound:
- Reduce the volume level on your amplifier. Overdriving the speakers can cause distortion.
- Check speaker wire connections for any loose strands or short circuits.
- Ensure the amplifier's impedance rating matches the speaker's 8-ohm impedance.
- Uneven Sound or Poor Imaging:
- Adjust the aimable tweeter to direct sound towards your listening position.
- Verify speaker placement and ensure they are equidistant from the listening area.
