What are you using for a sub and what is the crossover ? I find my CRM-2 to be excellent in terms of both dynamics and SPL but a proper sub or two that plays flat to 100 Hz and low down to 20 Hz is required for almost any speaker system to sound theater-like. Sunfire subs are not a good match IMHO. Something liike an SVS PB-13 ultra, Oulaw LFM-1 EX, HSU VTF-3 or higher etc.
