I always wonder what people mean when they want their front stage to "keep up". If you push those 3 15's to their limits, your front stage would be so loud that you couldn't possibly stand it. This concept of people thinking they need to keep up with their subs is terribly flawed.Well I'm thinking now of going with 3 of the Boston G2 15"s since I can fit them. When I say loud, I need something loud enough to keep up with three 15"s. Albeit these 15"s are not extremely powerful and more entry level, I want to use three because they have symmetry. I will probably do two of the US Acoustics Barbara Ann's and a Big Ben. For the price of one Rockford T2500 I could just about get all three amps and it would stay with the theme of being "budget". So when I say loud, I'm wondering could they keep up?
