I was wondering what you guys thought about the pros and cons of having 2 (10") Hsu STF-2s vs. 1 (12") STF-3 or VTF-3. In a 6000 cubic foot space would the two STF-2s provide more even response, greater coverage and SPL? I am willing to sacrifice the extra 5Hz or so of bass extension in order to get better overall SPL. My use is about 60-70% music, and I don't really watch that many LFE-intensive action flicks. I am also attracted to the greater flexibility of having 2 small subs, in that if I move to a smaller space I can put one sub to my bedroom system. My concern is if having 2 subs might create weird phase interactions in the room, but I guess I can always put the subs side by side in that case? I guess what this boils down to is whether 2x10" drivers at 2x200wpc is a significant improvement over 1x12" driver at 300wpc (350wpc for the vtf-3).
