Need Help Tuning Vintage Electro Voice Cabinets.

Here's my thought. I have a pair of REALLY nice looking 1966 Speakers with Barzilay cabinets. The cabinets have an Electro Voice SP15, a T-25, and a T-35 horn. The cabinets are sweet, but are not exactly tuned, I think..or am maybe wrong. There is an aproximately 4 by 10 inch hole in the bottom, functioning as a port(?)

What I want to know, given the size of the cabinets of 29 high, 22 wide, and 18 1/2 deep, and no bracing inside, can I tune the box to the sp15 and put appropriately sized ports in either the back or the bottom. Of course, I'm limited to the size of the box, as they are sweet looking, and my wife would absolutely maim me if I messed them up.

So, given the parameters of an Electro Voice SP15, and this size box, is there a way to seal the hole,(easy) and design an appropriately sized port to maximize the the box for the woofer. Maybe a brace, as well. The case is thick and heave partical board, with veneer on both sides.

Here are the photos:
