I'm wondering if my results are typical...
After adding a port-blocker, changing my 25Hz tune to 20Hz, several things occurred:
A 6db peak around 20Hz. I would not have expected this.
A 5db peak at 50Hz and a 4db peak at 63hz
I did not measure any change at the often mentioned 30hz mark where the lower tuned sub is supposed to fall off somewhat.
Prior to the 25hz-20hz retune, EQ'd response was flat to +-1.5db
My readings were adjusted using the SPL meter correction values.
