Desings for one 18" RD blowthru

4th order is sealed chamber firing into a ported chamber and the ported chamber is the only part of the box coming into the cab. I'm not sure if the sealed box tunneling into the cab is considered a 4th order, because that is exactly what I wanted to do but there has to be more to it than that I would think (size of tunnel has to have some effect on sound).

yea pretty much what i was thinking sealed and then chamber ported in to cab, i want to look into 6th order with 2 RD alpha 12's sometime.
