Many subs have irregular frequency response in the rooms they are used in.If the SUB doesn't have its' own amp,then you could try a "plate" amp with parametric EQ.Parts-Express has 500/1000W units with this feature.
Subwoofer Frequency Response question
I just started testing my frequency response with a Radio Shack SPL meter (digital). My subwoofer is a Paradigm PW-1100 (10 in) with Green Mountain Europa speakers. The room is small, 12 X 14 X 9. The frequency response is generally very good with bass response down to 25 Hz. My issue is I have a dropout of nearly 20 db starting at 45 hz through about 70 hz. I have not been able to change it by moving the sub or changing the settings (phase and crossover point). I also have the sub on an elevated platform of 1 1/4 inch MDF with spikes between sub and platform.
I am wondering if adding internal bracing and additional acoustic dampening material to the sub woofer would change the response characteristics in a positive way.
Any ideas would be appreciated.
