I dunno if this helps, but Q logic has a box out (you can even get it at Bestbuy!) and it can be setup as ported or sealed. You can swap the respective pieces of plastic, one being a sealed piece and one with a fatty hole in it. Pretty freakin sweet huh? Well damn, I got one...
do you even know the tuning frequency of it? Yah...i didn't think so, plus that frequency will change depending on the size of the subwoofer. I'm not "crapping" on you just saying installation is just as important (probably more inportant) than what stuff you buy.
