There seems to be some objection to Power Acoustik. I asked about using 2 Mofo 12's or one 15 Mofo and the A3000DB. For what these would cost what is a better alternative and what's wrong with them? A friend has the Plasma Shere TS 1929-2 w/ two FUBR 12's and it sounds great. What am I not seeing? Better choice, I'm all ears!
