Well, after spending ages playing with the tuning of my PB2-isd, M60s and Denon 3805 this is the best I can do.

I didn't realize until today that the Direct Mode did not high pass the mains, duh!

It would be nice if I could get a little flatter response, but I guess that is down to room acoustics. I have tried every possible sub placement and this is the best.

Oh no, I can feel some more experimentation coming on!
