ah i saw the thread with the results of that gtg. i think i actually went to popalock's house just after that because only 1 of his subs was working because he had built the new box for the other one to match the black box he brought. that dude is a crazy bass head haha. reading everyone's reviews of the dual caps at that gtg does make me think i could buy them and be sure that i will have no probs sub wise. EDIT: and i see those pics you linked to were in that thread as well. are the triple 8's the same size as those c8's? i had assumed they were bigger based on the pics but never really looked at measurements lol.
