Placement

Subwoofers operate at extremely low frequencies that are primarily omni-directional. Keep in
m

ind that frequency response and output level can be
depending on the acoustic properties of the listening room. Typically, the optimum location for
a subwoofer is tucked away in a corner of your listening room where the greatest output levels
and optimum low frequency extension can be found. The worst location for a subwoofer is far
away from any walls and close to the center of your room. Avoid these locations when possible.
Depending on the room size and type of furnishings in the room, perfect placement may not be
possible. Finding the best location for your environment will likely require some experimentation.
We suggest you experiment with the location during setup to find what sounds best to you when
seated in your typical listening position.

Caution! This subwoofer has electronics built into the cabinet. Do not place the cabinet
next to sources of heat such as furnace registers, radiators, etc., or near sources of
excessive moisture such as evaporative coolers, humidifiers, etc. The power cord should
be routed in such a way that it will not be walked on, pinched, or compressed in any
way that could result in damaging the insulation or wire.

Regardless of where you install your VX-11 subwoofer, it must remain in an upright position
(woofer facing forward). Using, shipping, or otherwise storing the subwoofer in any other
position for an extended period of time may result in damage to the unit not covered
by warranty.

To alleviate this condition, we recommend the following steps:
