Finally made it outside with some time on a nice day to coat this thing with Duratex.

Here are some graphs.

This first one is near field, no DSP no "room correction" this is pure sub. Starting at 7hz going to 138hz on this graph. (I ran the sweep 5hz -300hz but only so much fits on one screen).


The second graph is from the main seating position with the front main speakers included, still no DSP "room correction". It's not to bad , although I definitely need a second sub to smooth out the nulls.




Overall I'm extremely happy with the results of my first subwoofer build. I will play around with the DSP in the amp and the room correction in the AVR to knock down the peaks some. Nulls can't be EQ'd away, that takes multiple subwoofers to accomplish that. Definitely going to build a second sub this fall/winter.

(For those that might care, I am using a miniDSP Umik-1 calibrated measurment microphone)
