Did you end up adding rear subs to compensate or have you been able to work it out using the MiniDSP and positioning/placement/treatment changes?
I am trying to figure out where to best spend money right now. I want to buy two more SI 18's before they are gone but I also have zero EQ (aside from Audyssey MultEQ) on my subs. I can't decide if I want to work on EQ'ing what I have already or just focus on adding two more subs right behind the couch. Either way, a MiniDSP purchase will happen at some point. I am already working on treatments.
Hope this helps...
Here's my graph with the subs in the front
Here's my graph with the subs in the back
Here's all subs (Front and back) eq'd with the MiniDSP
I never tried eq'ing the front subs only to see what I could get.
I also never tried eq'ing the back subs to see what I could get.
I only eq'd with all subs on.
My setup is 4x 21's in the back (2x per corner stacked)
2x 18's in the back (1/4 away from the corners)
2x 18's in the front (one per corner)
Without the MiniDSP I have a null from about 15 to 30HZ and easily correct this with the Mini
I remember your thread and saw what looked like to be the same situation as mine.
If you could try the 2 subs you have in the back and take a FR to see if you get results like me.
If you do, you'll see tremendous gain with them in the back.
