i want to build a ported box for my 13w7, right now it is in the jl prowedge sealed box and would like to get a little more out of it.
want to use areo ports and try and keep the box around the size i have now.
was thinking 22L x 18H x 18D = 5581.12/1728 =3.22 ft3 less .21 ft3 for the sub
now that is 3.04 ft3 internal volume.
on the 1 site i used for a calc. using 2 4" ports on a 3 ft3 box tuned to 34htz it says port lenth of 16.6" so i will assume that is 16.6" ea. (not sure)
? 1. do not know how to figure out port displacement.
? 2. will this be a good box for my sub
any help would be great
