Well I didnt want to hijack Bruce's thread so heres my own results
This forums needs some threads anyway

So with the help from the BFD I have a nice little house curve going on. I feel more than happy with the results at this point and haven't changed a thing.
I know its sorta hard to compare the two graphs because of the differences in Y axis settings, but I actually cant find my original data file to go back and change the original "no EQ" graph, so this one will have to do.
Oh and one thing i learned. While setting the phase to 180 degrees may actually flatten things out on your FR, generally speaking, a sub located along the front soundstage will always sound better @ a 0 degree phase as it will be more in phase with the mains. This is something that worked in my situation and i urge others to take note of this. Work with the bumpier FR of the 0 degree phase setting and flatten it with help from the BFD and you will be much happier with the results.
