Just brought one of the Power Acoustiks FUBR 12s. Building a 2.2 cu.ft. ported at 34HZ.

What size should the port be if I wanted it to be rectangled instead of circled. Recs. are 4"(dia)12"(length) # of ports 1.

Also I was looking at the Lanzar Optidrive 12s. Should I sell the PA to a friend who wants and get the Lanzar, or keep what I have.
