That you guys who talk about 15's not being that great (as in efficient, and well designed) are right. After a few weeks of messing with my rig (ampeg svt12he and svt15e, peavey t-max) I just can't get any sort of punch. I've got all the balls and woof and dirt I could ever stand, but I have a feeling that I'm about to get lost in the mix when I play with other folks. So...I'm hoping to get $500-600 out of the two of those cabs. Should I go for 10's or 12's? I don't slap, or pop, and I love vintage tone. I was thinking either GK 212 neo, avatar 212 neo, Ampeg 610hlf, avatar 410 neo. Are 12's the compromise between the super punch 10's and the flop of 15's? I can try out some stuff being that musician's friend outlet is here in KC, but obviously not avatar. Thanks In advance for the help.
