Installation Considerations

Features and Benefits

employ a bracketless mounting system in existing ceilings. Simply cut a hole in the mounting surface, remove the grille from the speaker, connect the wires and place the speaker in the hole. Then tighten the four mounting “dogs” via the front panel screws. The dogs first swivel 90°, then clamp the speaker frame to the drywall as you tighten the screws.

Hole Saving Bracket

Installers can select to de-emphasize the bass or treble by 2dB to accommodate reflective surfaces and corner loading. This selection is accomplished via baffle- mounted controls that are accessible after the speaker has been installed.

Recommended Amplifier Power

For satisfactory performance, we recom- mend an amplifier with a power rating of five to 60 watts for the CM5MP, five to 75 watts for the CM6MP and five to 100 watts for the CM8MP. 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.

Available as an optional accessory, CM5 Series, CM6 and CM8 Series New Construction Brackets can be installed as a “hole-saver” before the drywall goes up. The drywall contractor cuts the holes as the drywall is installed, reducing installa- tion time and minimizing the chance for lost wires.

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.

Installation Considerations

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.
