Anyway I have to tell you I had 2 T39's Delta12lf, 20" wide V ed and coupled with a folding table,(not recommended) and half a side of a Euro Behringer 2500 amp.
Amp was turned 3/4 up and the dance floor shook. Rumbled so much that they asked for us to turn the bass down.
I almost cried (inside) with proudness.

Anyone that is thinking of building these subs for a band, I feel these Titans are the way to go, COME ON! 2 12" speakers rumbled the floor beneath about 70 people dancing. I have never felt so much power at my drum pedal
