What is your AVR setting when calibrating your sub?

[McLoki]

ok, so I am about ready to tear down my house and build a new one. (ok, maybe just a dedicated home theater room)

This is the best that I can get out of my sub. It does graph much worse than it sounds, but still - it looks ugly....

One question, when you all apply a BFD or other equalizer, do you put your AVR in stereo mode, pro-logic, or turn off all your other speakers when trying to calibrate your sub to your system?

The following graph is from stereo mode, before and after BFD - no gains, just cuts.

I am pretty sure the 80hz peak is coming from the poor placement of my front speakers, the big nulls are coming from a bad room design for HT.

Well, managed to mess up the image - here it is again....

Wow, you said it was ugly. You weren't kidding:D

I always put it in stereo mode and unhook the fronts. Not sure if this is right. But I have always been more interested in what happens down low and when I do a graph with the fronts hookled up it is very similiar in this range.
Anyway I am curious to hear the "proper" way to do this.

Here is the graph when I use sub alone. (all speakers turned down at the amp. Crossover is still active though... (80hz))
