thinking about doing whole new setup i have 2 pbx xa3000d's on the way and will probably sell one so i have 3000 watts at 1ohm and i want a really nice sql set up. i was thinking about 3 or 4 12"s or 15"s. i would like them to sound really good and im sure with taht much surface area they will be plenty loud i just don't want to spend over 900 on subs alone any ideas
