• Four extra heavy, shock absorbing
rubber mounting feet have been
included. If your subwoofer tends
to wander about slightly while in
use, place these feet just inside
the existing feet positions. These
shock absorbing mounts will let
the subwoofer rock freely, thereby
absorbing low frequency rocking
energy, allowing it to adhere solidly

The metal control plate serves as the
am pli Þ er heat sink and also as a conduit
to remove internal heat to the outside
and into the atmosphere. It can reach
tem per a tures of 60 degrees C, which
will feel hot to the touch, using nerves of
ß esh and blood as tem per a ture sen-
sors. As uncomfortable as it may feel, 60
degrees C cannot burn you, and in fact is
almost cool to copper, silicon, steel, and
aluminum, the materials from which your
subwoofer is con struct ed.

Magnetic Fields
We recommend that you place your
subwoofer further than two feet away
from your TV, VCR, tape deck or com-
puter, so the speak er’s magnet won’t
distort the colors of your TV picture or
erase your video tapes, audio tapes or
computer discs.
