Important enough and challenging enough, this 

feature gets its own section!  “PEQ” allows you to tame a “peak” in your room’s 
response.  Peaks are quite common, especially in large rooms or ones where your sub 
is far from your listening position.

frequency response until such time as you properly configure the PEQ. 
 

First

 you might ask yourself, “why use a PEQ?”  The reason is quite simple.  Your 

room.  See, most times even a superlative subwoofer which measures very evenly 
(we say “flat”)  in an open domain (no reflective boundaries) will

same in your home theater or music room.  Instead, colliding bass waves can build up 
and cause a “peak”.   This is where a parametric equalizer helps out.  A PEQ is an
