To mount your speakers on a wall, we have installed metal key-hole brackets on the back of the 370
IN-SR. Be sure to use a strong screw whose head and shaft will fit within the keyhole opening and slot.
Also be sure to drive the screw well into a stud or use a mounting device (such as a molly-bolt) that is
capable of holding the weight of the speaker. Never simply drive a nail or screw into sheet rock or
other wall materials. Always follow the above guidelines for safe speaker mounting.
For greatest flexibility, you can use pivoting ball-and-socket wall brackets of suitable weight rating
(e.g., Omnimount 50 Series, Vogel, etc.), usually available from your audio/video retailer. These can be
connected to the 370 IN-SR using the 1/4x20 threaded insert in the back of the cabinet.
Again, for safety, please use suitably secured wall anchors (such as molly-bolts), or screws driven into
wall studs.
Care and Feeding of Your Speakers
Clean your speaker cabinets using a soft cloth moistened with a mild, non-abrasive glass cleaner, being
careful not to wet the edges of the cabinet. Also, be careful not to get any cleaning fluids on the driver
cones or domes. It may be best to dampen the cloth with the cleaner and then wipe the speakers. After
carefully removing the grilles from the speakers by pulling them forward, clean them with a quick pass
from a vacuum cleaner using a soft brush attachment. This should remove any dust accumulation. 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, save the cartons, packing pieces, and plastic bags that came with your
speakers. They’ll 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.
