When making the cabinet with 3/4" wood, cut the port hole 4 5/8" diameter. I can't say what you'll get if you modify overall cabinet dimensions, but I expect it will be OK if you don't vary too much. Keep volume the same and leave the distance between port and cabinet floor the same. Also maintain the distance relationships between the woofer, the tweeter and the top of the cabinet.
