I cant find the specs, anychance someone might have them... OR can anyone tell me what I would need for a vented box tuned to like 18-24 Hz. I know its going to be huge, I dont care. Would it maybe work Infinite Baffle??

Other option would be a HT box using 6 JL Audio 8w6 subs. Im trying to figure out how to use WinISD and allows me to tune super low like 20hz. Anyone know of a box building application which allows me to pick a sub and then choose what I want it too be tuned to and then design the box?
