The only ported subs I have seen , were commercial, store bought ones and they sounded ok, but just not the sound I wanted. The issue I would run into using a ported box is I dont have the room for 4 ported refridgerator size boxs lol So I am just going to do sealed and see where this takes me.
Did you look at the SPL modelling graphs for the 4 subs I posted?
How does it look to you?
Its my first attempt at sub moddeling and, It seems like a tonne of output right from 10 HZ right up to my crossover at 80hz.
This will definitley have more output than my 2 paradigm x12's
