®
subwoofer. Our subwoofers exemplify
the best in modern audio technology, and are designed to produce remarkable amounts of deep bass.
Please read this manual completely to ensure the best possible performance from your Home Theater or
sound system.
SOLID BRASS ISOLATION CONES:
If your subwoofer comes with Solid Brass Isolation Cones be sure to install them into the bottom of
your subwoofer cabinet. They are an important part of the performance of the product and will improve
the bass definition. AC Sub
TM
125 owners: You must install the solid brass isolation cones for the bottom
vent to operate properly.
With the cabinet on its side, simply screw the cones into their receptacles on the bottom of the
cabinet. Then, with the cabinet upright, adjust the cones individually as needed to level the cabinet.
When the cones have been adjusted to the proper height, screw each nut up the threaded shaft flush with
the bottom of the cabinet to secure the height setting. If you intend to place your subwoofer on wooden or
vinyl floors, we suggest placing a penny under each cone to prevent any indentations.
PLACEMENT:
Recommended Subwoofer Placement:
a) Within a few inches of the room corner closest to your left or right front speaker (maximum low
bass output);
b) Within a few inches of the wall between your left and right front speakers (strong low bass output
with optimal blending to front speakers);
c) Near any other room corner or wall.
Other locations will provide varying degrees of low bass impact and blending with your front
speakers. We recommend listening to your system, with the subwoofer in different room positions, to
obtain a location with an optimum response.
A Special Note for Microburst
TM
owners: Due to the bipole configuration of your subwoofer be
sure to leave at least an inch between the rear woofer and your wall.
If you must place your subwoofer near baseboard heaters or forced hot air vents try to leave at
least 3” of clearance for proper ventilation. Do not place your subwoofer outdoors, or in any wet or
excessively damp environment.
Note: If you have an older, non-flat screen TV, please place your subwoofer far enough away from
your TV (approximately 2-3 feet) to avoid any color distortion from being caused by your subwoofer’s
powerful magnet(s). If you experience picture distortion, simply move the subwoofer away from the TV
until the picture becomes distortion free.
