LBM`s GroundPounder - LBM 15 x 4;RF T2500.1x 4, Termlab ->160+db !!!

[LBM]

I am getting about 150-151 db with 1500-2000 watts clamped power. And my question is how much gain I would expect with sealing the wall.

Will all the ports open it is close to 32 hz with one port close it comes down to 28hz with 10.4 sq inch area per cuft and with two port closed it comes to 24.5 hz with 7.1 sq inch area per cuft. Haven tried closing the port and it sound nice from 25hz to 45hz right now !!!

Ya there is a little room still left !!!!
