Installation Considerations

Recommended Amplifier Power

For satisfactory performance, we recom- mend an amplifier with a power rating of 10 to 100 watts for the CM5HD; 10 to 125 watts for the CM6HD and 10 to 150 watts for the CM8HD. Curiously, most speakers are not damaged by large ampli- fiers but by small amplifiers. If your system

is playing loudly, a small amplifier will run out of power very quickly. When an amplifier runs out of power it creates dam- aging “clipping” distortion. A large ampli- fier will play at the same volume without distorting. See the section on operating the speakers for more information about clip- ping distortion.

Installation Considerations

The illustration shows how a typical CM loudspeaker mounts into a ceiling.

Dogs swivel 90°, then clamp the speaker frame to the drywall.

New Construction Bracket serves as a “hole saver” when drywall has not been applied. It is not necessary when retrofitting to existing ceilings.

Knockout wire tie allows the wire to be secured to the bracket throughout the new construction process. It knocks out cleanly when the speaker is installed.

New construction wings instantly snap into the bracket without screws.

Frames are molded with a slight texture to assure good paint adhesion.

Mounting screws tighten the “dogs”, clamping the speaker to the drywall.

Rust-proof aluminum grilles make the CM series perfect for moist environments.

Wings are scored for easy size trimming.

Brackets and wings attach to the ceiling joists with nails or screws.
