PiAlign suggests a 5.5 cubic foot box tuned to 42Hz using a port 9.5" long and 9" diameter. You can also make the port rectangular, 10.5" x 6" and 9.5" long. These are inside dimensions of the port, and also inside dimensions of a cabinet. No displacement volume has been added, so you'll want to offset some for the space taken up by the parts inside.
