Try to come up with my own plans since I can't think of somebody else that can do it right now so here I go..

Dimensions-
48"= W
18"=H
34"= D

Multiplied the numbers 46.5 X 16.5 X 32.5= 24,935.625

Did 24,935.625 divided by 1728 and that = 14.430

14.430 Divided by two = 7.215

So that would be aproximetly 7.2 cubic ft per chamber before port displacement.

Using four 6" ports, two per chamber, trying to get a tunning of 35hz.

I would cut each port at 13" (length).


What do you guys think? Do you think by those dimensions it would sound good or no?

This is for two 18" BTLs/ MTs.
