installation precautions and tips
Please read these instructions completely for the best enjoyment of your Custom Series speakers.
• When you cut into the ceiling to install the speaker, do not cut through the facing or insulation that
may be above the ceiling. This facing is a moisture barrier. Use duct tape or wide vinyl tape to seal
any cuts.
• Keep debris and loose material away from the installation location. Do not allow debris to get in
the openings of the woofer basket. Debris and loose material can cause buzzing or rattling, and can
damage the woofer cone. Install plastic or fiberglass screening above the speaker to keep debris
away. Handle the speaker carefully.
• Do not let anything touch the speaker cone or dome. Do not clean the speaker with paint thinner
or any solvents.
• Consider the services of a professional custom installer. If you have any doubts about your own
abilities, it is better not to risk damaging your walls or ceilings, electrical wiring, ventilation ducts
or plumbing.
• Work with good quality, correct tools. This will save you time and assure superior results.
• Allow sufficient clearance.
• When using speakers outdoors, locations should be sheltered from direct sunlight, rain or snow.
Direct exposure will shorten product life.
• Combined impedance for speakers connected to each channel must be at least 4 ohm. This is the
minimum impedance tolerated by most amplifiers. Check with your dealer before wiring multiple
speaker pairs.
general mounting suggestions
Avoid placing the speaker within two feet (0.6 meters) of a corner. The acoustic reflections from surfaces
near the speakers can detract from the sound quality. Do not place the speaker behind heavy fabrics; if
you cannot see through a fabric, you cannot hear through it.
The ceiling speakers are designed for "infinite baffle" operation. The area behind the speaker installation
should be at least one-half cubic foot in volume to ensure proper performance. If the area is too small it
will limit bass response and cause a peak in the mid-bass range.
The panel on which the speaker is mounted must be rigid. There must not be any air leaks between the
area behind the speaker and the listening area.Mounting the speaker on a panel of a suspended ceiling
will adversely affect its performance.
