alright i got my box already built and ish but idk how to get the port down to where i want and to get the right port size for my subs.
the box is 18 high 23 deep and 36 wide. so thats 5.74cf net btw no clue if its net or gross im lookin for so the gross is 7.08cf and this also has a 3 high 15 wide 30 deep port in it which should be around 23 hz in tuning. would this port be correct or still to small. the subs need i think 60 inches of port a piece but idk how to calculate that so help would be appreciated. and the tuning if its not possible to get that low i would still be happy around 26 or lower.
