Anyone using this method. I purchased an OM system from PE and before i returned it for a tuneup i got some interesting results. I had a serious null around 55hz, with a BIC-200 next to my LP i was able to fill in the void the null created. Further attention to delay would be needed and my plan is to utilize the MiniDSP and a 12"sealed Dayton with a Dayton SPA-240 plate amp....
I took measurements from three position and this is very exciting stuff. This all came about when i did some HD tests and found some high numbers. Seems my Audyssey was attempting to correct the null by raising the null at 55hz. Good thing it was limited to raising it by only 10db Lol.

The red line is the measurement at the LP, blue line is the same, but add in the bass from a BIC-200 sub positioned next to the LP. Only thing that is left is to tame the peak with a nice PEQ filter and delay the signal to matched the main subwoofers.....more to come
