So I want to build my bass player a cabinet smaller than his 8x10. I built the 2 x 15 cabinet described on the sunn shack page 24 x 36 x 15 and when I was done realized 15's aren't gonna fit all that comfortably. what am I gonna do? I think if I front mount the speakers it will work ok but will the sound be all wrong? should I use what I've already built or should I scrap it and build a new one 24 x 40 x15? He's using an old Ampeg B4 head oh yeah, he wants to do two 10's up top and one 15 on the bottom is that gonna sound like trash?
