i am trying to figure out a box for a Treo csx 15" , it does have the pole vent. If someone could help that would be great. the problem is the face has to be slanted a little cause i only have 14" tall for a 15" sub. the port has to be on the face so i was thinking on using 2 6" aero ports or maybe smaller ones.
my max Dems are:
looking for around 4.5cft after port and displacement. tuned around 36-38hz.
