Frequently Asked Questions - CI520 Phase Technology
How do I install the Phase Technology CI520 in an existing ceiling?
First, cut a hole of the correct size (7.25" diameter) using a template. Run speaker wire from your amplifier to the hole. Connect the wires to the speaker terminals (observe polarity: red to positive, black to negative). Insert the speaker into the hole and tighten the mounting screws to engage the dog-leg clamps until snug. Finally, attach the grille.
Can I paint the grille to match my ceiling?
Yes, the grille is paintable. Remove the grille from the speaker, clean it, and apply thin, even coats of latex or spray paint. Avoid clogging the holes. Allow to dry completely before reattaching.
What is the recommended amplifier power for the CI520?
The CI520 handles up to 50 watts RMS (100 watts peak). An amplifier delivering 20-100 watts per channel at 8 ohms is ideal. Ensure your amplifier is stable into 8 ohms to avoid distortion.

The impedance is 8 ohms. This is standard for most home audio receivers and amplifiers.
Can I use the CI520 in a bathroom or outdoors?
The CI520 is designed for indoor use only. It does not have weather sealing. Exposure to moisture or extreme temperatures may damage the speaker.
How do I clean the speaker grille?
Remove the grille and gently vacuum with a soft brush attachment to remove dust. For stubborn dirt, wipe with a lightly dampened cloth. Do not use harsh chemicals or submerge the grille.
