I have to 12" kicker L7's in a small sealed enclosure (131/4 H, 131/4 D, 281/2 W) and it sounds pretty good but i want a more solid box. That was just a start off box. Now I'm looking for nice smooth solid bass and good SQ. Could be ported or sealed but I need some advice and what type of specs should I look for with which ever one I choose.
