I have 2 mofos, in a pretty dang close enclosure which mesures 36Lx 21 1/2Wx 16H the port is in the center it is 4W by 19 1/2 im pretty sure that this way to small. PA says Tuning: 40 Hz Port size: 3"(dia)x6.75"(length) number of ports: 2 so i would /could i get this box to that spec or do i have to seriously rework it in which it be easier to just make a new one?
kinda confused....lol.. is ur current box rectangle port witha width of 4 and height of 19.5 or is it a roudn port with a dia of 4 and length of 19.5??
however i would remake the box anyways.... and do slot port, reduces chance of port noise and you can make bends that allow you to have a longer port and in correlation have more port area.
