I'm planning out a system, and need to figure out what kind of box I'm going to use. I plan on running either AQ sdc2.5 10"/12" or DD 1510/12 or DD 2510/12 as of now. Possibly T3 Audio. That's definitely subject to change. I have more than 2400w on tap (eD 9.1s strapped). I'm simply looking for a daily groundpounder that emphasizes the lows, but still can play decently say up to 50-55hz or so. Not looking for numbers because I don't compete. I'm really attracted to the thought of using a 4th order, but looking for input from people with greater knowledge than me (not saying I have a ton). I want to do something different than the average ported box.
