Mystery speakers, prototype?

Does anyone know what these are? Who makes them? There is nothing stamped anywhere on them. The fronts are a fiberglass casing and they weigh over 150 lbs. each.

Ok, the phillips tweeters and shape kind of remind me of some test speakers i spied in the GA Tech audio lab ages ago. It was semi cylindrical section at the top with 4 tweeters and maybe 4 mids. My memory is hazy but it was an attempt to achieve very wide dispersion. certainly no vertical dispersion and i kind of remember the tweeters and mids time aligned, but i may be confusing it eith another stepped three way. the lab was fond of phillips, vifa and eminence though
