Hello all, again,
I decided to try again from scratch and see what I could come up with. I still wanted to go for a flat response as opposed to a house curve as a flat response sounds fine for me. Also this time when I added in the mains I matched the level of the mains with the subwoofer before measuring unlike before when I think the mains were 3-4 dB above the level of the subwoofer.
Anyway here is what I came up with:
My initial response. Subwoofer only:

After 12 BFD filters later. Subwoofer only:

But then when I added in the level matched mains, a huge dip developed. Subwoofer and mains:

I took out the two filters that I had had above the crossover (90 Hz) and then remeasured, again with both subwoofer and mains, added two filters to flatten the response and came up with this. Subwoofer and mains:

I then wanted to see what the response was with just the subwoofer and came up with this. Subwoofer only:

Even though the response is boosted above 100 Hz well above the target line I figured that with most LFE content there probably is not much material above 100 Hz so the LFE content in movies won't sound out of wack. If I didn't boost that area above 100 Hz then my subwoofer + mains would have the huge dip as shown before.
Overall, everything sounds great!!
