Q_man if at 19 feet your systems SPL is what you say it is, how come your system has not taken off and is still on ground :) Did you know that the Concorde generates 130 db SPL at take off?
SPL measurements are done at 1 meter, not at 19 feet, God only knows what your systems SPL's must be at 1 meter. I would not like to go near it!
