[QUOTE="T3mpest, post: 8261667, member: 560148"] It could be done, but he'd want quite a bit of them.. If you went with 2 18's, he would want 4 18 inch passives and possibly not have room to fit them.. Other issue is while the HDC's can play well under tuning passives won't. They roll off a little harder than a ported box would and can be mechancially damaged. You'd want to make sure you use a SSF for that reason. Anyway it would save you all your port displacement, if you can fit that on the other faces of the box. HDC 18's like what, 8 cubes net each? You'd still need 16 cubic feet then give or take a bit. Anyways OP.. That should answer most of your questions.. IF you can fit subs facing up and then do 1 passive on each side, that'll cancel out their vibration when they get moving. Probably want to invert mount the subs, to give youself room in the box for the passives depth.. I once did 3 passives all facing rear and the passives were strong enough to move my box across my carpet.. It was 9 cubes of double layered MDF with a 50lb sub in it, well over 200lbs, slid it like it was easy lol. [/QUOTE]
