tweeter protection

A solid state device reduces power to the tweeter when the loudspeaker is operated at unsafe power levels. It resets automatically when power is reduced to a safe level. Note: the tweeter protector provides a significant level of protection. However it does not guarantee that the tweeter cannot be damaged. Always be careful when operating the speakers at a high volume level.

tweeter attenuation switch

A 3-position switch located on the tweeter plate serves as a high frequency contour control. The mid position offers a “normal” response suitable for most applications. The positive (+) position provides the most output and is recommended for off-axis listening or if the speakers are mounted very high. The negative (-) position provides the least and is recommended for reflective “bright” rooms. The mid position is the best starting point. Due to room acoustics and/or personal preference, you may prefer either of the other positions. Be sure to try all of these positions and decide on your preference before installing the grills. If you find it necessary to re-adjust the tweeter levels after the grills have been installed, please follow the removing the grille section on page 6.

woofer

The high-excursion woofer employs a barium ferrite magnet structure for well damped, extended bass and high efficiency.

pre-wire connector

Gold spring speaker wire connectors are provided to facilitate simple, painless pre-wiring and installation. Just plug and play.

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.
