Well right now I have two Type R 12's in a 5 net cube box. I'm looking to upgrade to a set of 15's. THe biggest box I can get would be 14 H X 32w x 30 deep. That gives me 6.288 net cubes before driver displacement. WHat two 15's would work good in my application ? Budget is $400 total for both subs Amp does 1200 Rms @ 1ohm Want a pair of 15's that has about the same or better Sq than my R's and gets louder.
i posted this a while ago but i cant find it, unless you do it diagonally i dont know how your gonna fit 2 15s on 32/30/14" its not really possible, but thats plenty of cubes if you can do it
you dont have enough space for 2 15s. 3.1 is really kinda too small NET and your going to need port too so 2 15s ported is out of the question. choose sealed or go to 2 12s
