    I looked up the patents (US3,819,005 and 3,819,006) filed in 1974. The inventor, James Westlund of Arizona filed a third related patent US4474258 in 1982. The patents focus on the mechanical construction of the designs and give very little explanation of the advantages or principles of the designs.

    I'd buy them. Might be fun to experiment with and make something similar to Duevel speakers.

    What advantage is there over a common 8" ceiling driver etc? No room required above the ceiling?

    I saw an old 50s sci-fi movie using a 511 horn as a death-ray machine. So maybe I can't talk too much about weird looking speakers
