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/Mono 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.
