i have a 15" tc-9 hybrid, 3.4 cubic feet enclusure tuned to 34 hz. it slams, needs around 1000 watts to really get it going. let me know if you are interested. can get you pics and all if needed. just keep in mind that shipping will be outrageous because everything is so heavy. sub alone is 35 lbs. let me know, would definately suite all your SPL needs
