I don't recognize the cabinets, but Bozak made many cabinets, and sold drivers for use in other maker's cabinets, so who knows what they are. I'd feel around to see if they are 2 ways or 3 ways, and if there are more than 1 woofer.
The shape looks like like the later, smaller (but still big), versions of the three way with a single tweeter and a small midrange. The older, iconic, big Bozaks have one or more 12 inch woofers, an 8 inch midrange (maybe some have more), and 2 or more tweeters. So feel for the woofer(s), size of the mid, and whatever combination of tweeters the speakers have.
