You often hear the term “subwoofers are non-
directional.” This is not true. It is harder to choose
subwoofer placement when low frequencies are
crossed. The wider the room, the more directional the
subwoofer. The easiest solution is to use two (2)
subwoofers, feed a mono signal to both and place
them in the front, one on the left and another on the
right.
While having two (2) subs is better than one, the
MONO signal that drives those subwoofers keeps
them from projecting the three dimensional images in
the sub-harmonics. Using two (2) subwoofers allows
you to cross the subs up to 150Hz sound quality,
imaging and staging. In some applications, you might
have small front speakers or planar speakers. The
two-front-subwoofer system is an excellent solution
to planar speakers’ low frequency response early roll
off from 150Hz on down. When placing these
subwoofers in a close proximity to the stereo satellite,

Suppose you have only one (1) subwoofer in the
room and it is placed on the right side of the room. If a
