Sorry I'm late, by a number of years! This is my first post!!! The internal design of the hartsfield enclosure does not appear to be very similar to the internal drawings of the Jubilee I've seen on this site, though the exterior bears a resemblance. Lets face it, both were designed with a 90 degree corner in mind, both use folding and a pair of exits into the room. Those constraints will drive some commonality, but the similarity appears to end there. The distinctive feature that seems to be the subject of the Hartsfield patent was the "convertable" portion, where an 8 inch driver could be installed into a port of the enclosure, and then replaced with a larger driver in another location when the owner had more money to spend. This apparently was not a very successful option because it was discontinued.
