The Model 372 PBM Powered Subwoofer should be placed in the front of the room, close to a

corner. Every room has its own unique sound, and flexibility in the exact placement of the subwoofer

is always desirable. In general, the closer the woofer is placed to a corner, the more bass response you

will hear. However, in many rooms, corner placement can produce too much bass and the subwoofer

will work best well away from the corner. Experiment to find the best position in your room. Refer to

the wiring diagrams in the subwoofer's instruction manual for the correct wiring scheme for your

particular setup. Then proceed with listening.

Subwoofer Tuning

Start your listening with the high-pass filter set at 80Hz, the phase switch set to normal, and the

level control all the way down (counterclockwise). Play some music that you know has good bass

content, and turn the level control up until you just start to hear the subwoofer working. Now, sit in

your normal listening position and determine whether the subwoofer is playing loud enough and

filling in the bass frequencies of the music evenly. If it needs adjustment, change the setting of the

level control to compensate. If the bass still seems too heavy, move the subwoofer away from the

corner. If the bass seems too thin, move the subwoofer closer to the corner. Small differences in

positioning the subwoofer can make big differences in the overall bass response. When you find a

position that seems to work well, try switching the phase switch between its two settings, listening

closely for the smoothest bass response. Remember, the most common error is to play the

subwoofer too loudly.

Listening Levels and Power Handling

The power recommendation for these speaker components assumes that you will not operate your

amplifier/receiver in a way that produces distortion. Even rugged speakers like System 370 THX can be

damaged by a moderately powered system driven beyond its capabilities. The harsh amplifier clipping

that occurs in this situation may cause damage to the speaker system that is not covered by the

warranty. The System 370 THX will play very loudly when provided with enough clean power to do so.

Don't starve your system for power! There are several suitable receivers, integrated amplifiers, and

multi-channel power amplifiers commonly available. Consult your local audio/video specialist for

additional information.

Care of your Speakers

Clean your speaker cabinets using a soft cloth and a mild, non-abrasive glass cleaner (such as Windex),

being careful not to wet the individual drivers or the edges of the cabinet. Spray the cloth, not the

cabinet. Do not rub, but lightly wipe the dust and fingerprints from the surface. A dusty grille is easily

cleaned by gently using a vacuum cleaner with a brush attachment on the grille fabric. Avoid placing

your speakers in direct sunlight or near a source of heat that may, over time, fade the finish.

Important: Save Your Boxes! If you can do so, save the cartons, packing pieces, and plastic bags that

came with your speakers. They will be useful in case you move or have to ship your loudspeakers for any

reason. In any case, save all packing materials until you are certain that the systems have suffered no

damage in shipment. If you find such damage, either visible or internal, contact your dealer immediately for

the proper return procedure.
