I have a JBL M151-8 Bass guitar speaker, and I am building as close a copy as possible to the JBL MR815 cabinet. The only detail I haven't settled on yet is the size of the port. Can anyone help me with this?

The JBL M151-8 is best used in cabinets from 1.0ft3 to 3.0ft3 tuned to 70Hz. PiAlign recommends 1.75ft3 tuned to 70Hz with a rectangular port 4 7/16" x 7 7/8" and 6" long.
