4. Setup and Installation
Proper installation is crucial for optimal sound performance and speaker longevity. Follow these steps carefully.
4.1 Choosing a Location
Select a location in your wall that is free from obstructions (studs, electrical wires, plumbing). For stereo sound, position speakers equidistant from the primary listening area. For home theater, refer to your receiver's manual for recommended speaker placement.
4.2 Preparing the Wall
- Use the provided installation template to mark the cut-out area on your wall.
- Carefully cut along the marked line using a drywall saw or appropriate tool. Ensure the opening is clean and precise.
- Run speaker wires from your amplifier/receiver to the cut-out opening. Leave enough slack for easy connection.
4.3 Speaker Wiring
Before connecting, ensure your amplifier is off. Strip approximately 1/2 inch (12mm) of insulation from the ends of your speaker wires.

- Press down on the red terminal tab on the speaker and insert the positive (+) wire (typically red or marked). Release the tab to secure the wire.
- Press down on the black terminal tab and insert the negative (-) wire (typically black or unmarked). Release the tab to secure the wire.
- Connect the other end of the wires to the corresponding positive and negative terminals on your amplifier/receiver.
4.4 Mounting the Speaker

- Ensure all four mounting clamps on the speaker are rotated inward (vertical) to allow the speaker to fit into the wall opening.
- Carefully insert the speaker into the cut-out opening.
- Using a screwdriver, tighten the screws located on the front baffle of the speaker. As you tighten, the mounting clamps will rotate outward and secure the speaker firmly against the drywall. Do not overtighten.

The metal grille is paintable to match your wall color. Once the speaker is mounted, align the grille with the speaker frame and gently press it into place until it sits flush.
5. Operating Instructions
Once installed and connected, your speakers are ready for use. Turn on your amplifier/receiver and select your audio source.
5.1 High-Frequency Attenuator
A detailed view of the 1-inch silk dome tweeter and the high-frequency attenuator switch, which allows for adjustment of treble output (-3dB, -6dB, or 0dB).
These speakers feature a built-in high-frequency attenuator switch, typically located near the tweeter. This switch allows you to adjust the treble output to suit your room acoustics and personal preference. The available settings are usually 0dB (flat), -3dB, and -6dB. Experiment with these settings to find the optimal sound balance for your listening environment.
6. Maintenance
To ensure the longevity and performance of your speakers, follow these simple maintenance guidelines:
- Cleaning: Dust the grilles and speaker frames regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, but avoid excessive moisture.
- Grille Painting: If you choose to paint the grilles, use a thin coat of spray paint to avoid clogging the perforations, which could affect sound quality. Allow the paint to dry completely before reattaching.
- Inspection: Periodically check the mounting screws to ensure they remain tight.
7. Troubleshooting
If you encounter issues with your speakers, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from speaker | Loose or incorrect wiring; Amplifier off or input not selected; Speaker damaged | Check all speaker wire connections at both the speaker and amplifier. Ensure amplifier is on and correct input is selected. Test with another speaker if available. |
| Distorted sound | Overdriven amplifier; Loose connections; Damaged speaker component | Reduce amplifier volume. Check all wiring connections. Inspect speaker for visible damage. |
| Uneven sound balance | High-frequency attenuator setting; Room acoustics; Speaker placement | Adjust the high-frequency attenuator switch. Consider speaker placement relative to listening area. |
If the problem persists after trying these solutions, please contact Monoprice Customer Support.
