1. Choose the desired location for the speaker, ensuring it is at least 1 inch away from any ceiling joist.
2. Use the included template to mark the cutting area for the speaker hole.
3. Using a drywall saw, carefully cut out the hole while holding a shop vacuum hose to collect dust.
4. Feed the speaker wires through the hole and connect them to the speaker's red and black connectors. Ensure a secure connection by pressing down on the levers while inserting the wires.
5. Insert the speaker into the hole, making sure the insulation is not obstructing the speaker.
6. Tighten the screws on the speaker using a cordless drill until snug, then finish tightening with a screwdriver.
7. Aim the tweeter and speaker for optimal listening, which can be adjusted later if needed.
8. If desired, spray paint the magnetic grille to match your ceiling and attach it to the speaker.

3. Adjustments and Tweeter Attenuation

To adjust the sound of the speaker, you can use the pivot feature to direct the tweeter and woofer towards the desired listening area. Additionally, the treble attenuation switch can be accessed on the crossover network to adjust the high-frequency response.

4. Pairing with Installation Kit and Speaker Enclosure

The Klipsch CDT-3650-C II In-Ceiling Speaker can be paired with the Klipsch IK-650-C installation kit and the ME-650-C fire-rated speaker enclosure (both sold separately) for optimal performance and to meet local building codes.

5. Troubleshooting Tips

• If the speaker is cutting in and out, check the connections between the speaker wires and the speaker's connectors.
• If the sound is distorted or unclear, adjust the tweeter and woofer direction or use the treble attenuation switch to modify the high-frequency response.
• If the speaker is not producing sound, ensure it is properly connected to your amplifier or receiver.
