Hello, I just finished a complete upgrade to my theater room. I have three Fusion-12 speakers as my L/C/R and my surround speakers are CHT PRO-10s in a dedicated 3000 cubic foot theater room. I have (5) 18" subs... (4)sealed SI 18HT in Erich's 4cf flat packs and a Josh Ricci designed HUGE ported sub good to 8Hz! I have an Oppo 103 Blu-ray player, Onkyo 818 AVR and a Panasonic AE-8000 3D FP with a 125" 2.35:1 scope AT screen. I have a very good collection of concert and movie Blu-ray discs, SACD, and DVD-Audio. Please PM me to set up a demo....
