may be above the ceiling. This facing is a moisture barrier. Use duct tape or wide vinyl tape to sealany cuts.Keep debris and loose material away from the installation location. Do not allow debris to get inthe openings of the woofer basket. Debris and loose material can cause buzzing or rattling, and candamage the woofer cone. Install plastic or fiberglass screening above the speaker to keep debrisaway. Handle the speaker carefully.Do not let anything touch the speaker cone or dome. Do not clean the speaker with paint thinneror any solvents.• Consider the services of a professional custom installer. If you have any doubts about your ownabilities, it is better not to risk damaging your walls or ceilings, electrical wiring, ventilation ductsor 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 theminimum impedance tolerated by most amplifiers. Check with your dealer before wiring multiplespeaker pairs.general mounting suggestionsAvoid placing the speaker within two feet (0.6 meters) of a corner. The acoustic reflections from surfacesnear the speakers can detract from the sound quality. Do not place the speaker behind heavy fabrics; ifyou cannot see through a fabric, you cannot hear through it.The ceiling speakers are designed for "infinite baffle" operation. The area behind the speaker installationshould be at least one-half cubic foot in volume to ensure proper performance. If the area is too small itwill 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 thearea behind the speaker and the listening area.Mounting the speaker on a panel of a suspended ceilingwill adversely affect its performance.3
