Introduction Installation in Brief

Level Knob
Setting the level too high will cause the bass to seem bloat-
ed and is the single most common cause of bad sounding
subwoofers. A rule of thumb is that the subwoofer should
not draw attention to itself, but should simply make the sys-

configuration of your listening environment, the placement
of the unit, and your seating arrangement. Due to the way
bass sound waves develop in different rooms, there is
no rule of thumb for setting phase. For instance, if your
room has a peak at the subwoofer crossover area, you
may wish to set the phase so the actual acoustic outputs
of the subwoofer and main speakers are out of phase.

Standing Waves
Sound coming from a speaker bounces around in a room

It had long been the practice of stereo buffs to connect their
television to a stereo system. The advantage was the use
of the larger speakers and more powerful amplifier of the
stereo system. Even though the sound was greatly improved, it
was still mono and limited by the broadcast signal.
