Can the port be 6" wide by 3 1/2" tall and 10" deep? Or better yet, 10"w x 3 1/2" x 6" deep?

The port should be 6" x 3.5" and 10" long. It doesn't matter if the wide dimension is horizontal or vertical, although if the tweeter is mounted internally, it's a tight fit and has to go the way it is. But if you move the tweeter up on top and move the woofer up to keep the distances the same, you can change where the port is. Don't change the length though, it should always be 10". Also, remember this is for the stock box size. If you make a larger box, the port size changes. You want the Helmholtz frequency to be 38Hz.
