I reckon if you double the drivers, you double the box size.Hello, i have 2 jl audio 12w6 and right now i have a bandpass box that my cousin gave me. I have heard a lot of bad things about the badpass box so im trying to find a good duel ported box for two 12w6. If you go to the spec tab in the link it will tell you the measurements of a single ported box for the w6 but not the measurements for a dual.
