[QUOTE="Trixter, post: 3009739, member: 542668"] port length is determined by the port area and box volume. port volume means nothing except to find it's displacement. it needs to be square. what i would do in your case is have the port as tall as the back of the box. yeah, the opering at the front will not be all the way from top to bottom, but at least you maintain squarness. you have 8.5"H at the back. add 3/4" mdf for the bottom of the port and you have a 7.75"H port.
