Subwoofer Placement
There is no argument among audio
professionals that the loudest bass output
from a subwoofer comes from corner
placement. The sound flaring outward from
a room corner focuses low frequencies
giving them no place to go but toward you.
In the case of subwoofers, there is no
automatic penalty in giving overall balance
for this peak bass, since your main
speakers can be located elsewhere. It still
may be too much bass for your room or
(more particularly) your favorite listening
spot in the room, but unless you are seated
in a “void” spot, where sound from the sub
is cancelled or diminished by out-of-phase
reflections from elsewhere, there should be
plenty of bass from corner placement.
If you are seated in such a void spot, your
only real choices are to move either the
subwoofer or your listening position until
the bass returns to the point that satisfies
your listening criteria. Turning up the level
control or changing the crossover point
almost certainly won't help much. But
flipping the phase control 180 degrees
sometimes may make a difference,
especially if the void is a product of
cancellations caused by interaction with low
frequencies from your
main speakers.
Using Two Subwoofers
If you choose the use two woofers, the
sound output will double (an increase of
5dB). Locate the woofers with one in each
corner and experiment with the location and
phase control to achieve the best bass
response.
Always drive each woofer through the
Left/Mon input even though you are driving
one woofer on a right channel drive and the
other with a left channel drive. If your pre-
amplifier has a single Sub/LFE output, use
a 'Y' cable to split it into two outputs.
