Care of Your Speakers
Clean your cabinets using a soft, lint-free cloth. If you wish, you can slightly 
moisten the cloth with plain water. Do not use any other cleaning agents 
or chemicals. Be careful not to get any water on the driver cones or tweeter 
domes. After carefully removing the grilles from the speakers by pulling 
them forward, gently clean them with a quick pass from a vacuum cleaner 
with a brush attachment. This should remove any dust accumulation. Reat-
tach them by lining up the magnet depressions in the back of the grilles with 
the magnets on the speaker baffle and slowly moving them closer until they 
connect with each other.
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 car-
tons, packing pieces, and plastic bags that came with your speakers. 
They will be useful in case you move or have to ship your loudspeak-
ers 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.
