Ok, some serious improvements have been made!

I started by turning sub2 (the one in the bay) off. This made an immediate improvement to the frequency response. That ~45Hz mountain almost disappeared. I tried one sub in various positions including the corners Wayne suggested and, surprisingly, the smoothest frequency response came from the position it was in originally.

I then decided to be a bit bold and hooked up the second sub, trying them together in different locations, co-locating and taking many measurements. The best I could get was with sub1 where it was and sub2 now sitting in the corner next to it. This produces a graph that looks like the uncorrected attached.

I think I should probably have gone through some recalibration at this stage as it's clearly running a bit hot. Instead I upped my target within REW and added some filters. I've managed to generate the attached corrected file which, I think, should sound pretty good.

Full range sweeps to ensure good integration are a bit beyond me at the moment. I ran a couple but couldn't decipher them so I'll use my ears for the moment. We're currently watching the LOTR trilogy; we did FOTR last night, it's Two Towers tonight and then ROTK on Saturday. That should give us a nice comparison.

Any comments or further suggestions? I'm going to play some of the scenes a couple of times tonight, with and without the BFD in place to see if it makes a noticable difference.
