I'll have to think about it my master. I am currently getting a work out moving subs around again. I'm placing the 600 back underneath the center channel as it looks cool and the above graph was done with that setup and no EQ, pretty flat.
I'm going to place one 350 on the rightside shorter wall, and the second 350 on the opposite left wall, approximately centered.
Right now I'm using a adapter from partsexpress and splitting things at the Denon, and the 350's are daisy chained.
