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, 

Placing the subwoofer in the corner of the room will 

the subs will enhance low frequency extension. It will 

produce  a  more  boomy  effect,  often  preferred  for 

be better to have a stereo subwoofer to help in the 

movies  and  sound  tracks.  For  a  music  application, 

lower bass notes and their placement. 

place the subwoofer as shown above or against the 
front wall, about a third of the room width.

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

Dual  Subwoofer  Setup  with  Mono 

bass guitar player was standing on the left side of the 

Signal

stage and played an EE note (42Hz), then the sub will 
also respond to that from the right side of the room 
and completely destroy the stage. 

This is a BETTER setup. In a dual subwoofer setup, 
the  subharmonic  frequencies  (black  arrow)  always

The    black  arrows  represent  the 
subharmonic frequencies.

The gray arrows represent the lows, 
mids  and  highs  as  they  follow  the 
action.

The  best  response  is  achieved  when  the 
subharmonic  frequencies  are  dynamically 
synchronized with the rest of the audio system, the 
black and gray arrows are identical

Single Subwoofer Setup

This is a GOOD setup. The subharmonic frequencies 
(black  arrow)  always  move  towards  the  sub  in  the 
single sub setup while the lows, mids and highs (gray
