I'd love to see graphs 1 vs 2 vs 4 vs 8. I have no doubt that there was improvement with each iteration as you probably didn't choose optimal locations for each configuration.
With the number of subs you have, you should try a double bass array. The result would be much better (if your room has a rectangular layout).
I only have one row of seats, and this was a single-point measure at ear position in the central seat.
It is quasi-L-shaped, and placement options are fairly limited. I thought I picked the best location for each sub given the limited layout.
I have a feeling that I could now be getting additional phase issues that I wasn't before because of the complete differences between the types of woofers and types of amps I use.
4 different types of subs and 2 different brands of amps (soon to be 3 types YAY).
If I did it all over again, I'd probablly just stick with all LMS-18's and FP14K's. With perhaps 1 FP10K for the kick bins. But I haven't heard either amp yet, but I have heard "mostly" good things about them. I not sure yet...
My room has massive modal issues, peaks at 28 to 45hz, and dips at 50-80hz. and a mix of dips and peaks between 110-200hz.
I hate it, it sucks. and this is WITH 100 cubic feet of acoustical foam treatments. YIKES
I'm fairly sure the dips at 10-15hz are woofer/amp mis-match phase issues, as I said already.
Here is the measurement retaken with mains on, CM-140 mic c-weighted, no other mic/soundcard corrections, no smoothing
Green is 4 subs uneq'd, yellow is 7 subs uneq'd, red is 9 subs uneq'd and blue is 9 subs eq'd
