I think he has 2 lascala's in front and was considering a third for center channel. His surrounds I believe are true surrounds and not full range like a forte.
My system did consist of chorus II mains and a DIY chorus center, front stage stage. Rear surround was chorus I's. It did sound good but I lost the chorus I's when I got a deal on 4 revel c30 surrounds. I like the revel surrounds better, I liked the more ambient sound. The chorus I's at times seemed to draw the sound to the rear.
This has been my experience with full range surrounds, ymmv. Not trying to argue with anyone I am far from an expect. I ran middle level onkyo 7.2 recieve in an 11 by 17 by 8 ft room. Maybe room size, conditioning etc. could other be other factors to consider? Just trying to help from my experience. Islander I would love to hear your system, I am sure it sound fantastic! Curious how big is the room your setup is in, thanks.
