Caring For Your Subwoofer
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.
