The 4.5 PBM has an elegant Gloss Black top panel. Special adhesive tape has been employed that is

designed to hold the top firmly to the cabinet, yet allow release without damage. Should you wish,

you may remove the gloss top by carefully pulling it up and away from the enclosure. Under the gloss

panel, the top of the enclosure is finished in the same Black Oak laminate as the rest of the enclosure.

You should use care when cleaning the Gloss Black top. Use a soft natural fiber cloth (not paper

products, as they can scratch) slightly dampened with water. You may also use any of the specially

formulated plastic polishes available on the market, should you desire.

NOTE: The Gloss Black top is shipped with a protective paper layer attached. In order to remove this paper

layer begin peeling it up at one corner and gently and carefully pull the paper off at a sharp angle so as not

to pull the top itself from the cabinet.

Avoid placing your speakers in direct sunlight or near a source of heat that may, over time, damage the

finish.

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

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

reason. In any case, save all packing materials until you are certain that the system has suffered no damage

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

return procedure.
