Models 451 LR, 453 C, and 454 SR

If the bass 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.

Mounting

The Model 451 LR and Model 454 SR speakers can be mounted in a variety of ways:

On the wall. To surface mount your speakers on the wall, we have provided two steel keyhole

brackets already installed on the back panel of the cabinet. Simply place the large openings of the

bracket over the heads of pan-head screws (securely screwed into wall studs or wall anchors), and slide

the cabinet down onto the shaft of the screw. Ideally, the acoustic center of the speaker (the tweeter)

should be within two feet of ear level when you are in a seated position.

On optional pedestal stands. The pedestal stands are provided with complete instructions and all

necessary hardware required for installation. These stands allow placement flexibility and a stable base

for a variety of floor surfaces, including deep pile carpeting. The height of the pedestal stand is

matched to the speaker for optimum performance.

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 450 THX can be

damaged by a moderately powered system driven beyond its intended capacity. 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 450 THX will play very loudly when provided with enough clean power to do so. 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 using a vacuum cleaner with a brush attachment and gently vacuuming 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.
