Question Rear Loaded Horn

I came across a patent the other night, of a rear loaded horn that is suppose to eliminate the problem of the back wave being 180 degrees out of phase with the front wave. Is anyone able to discern if our chain is getting yanked on this one, or is this possible. Ive attached the patent for you'all to puruse.

I'd be very interested to read it... apart from one slight difficulty (can you guess what it is? )

For what it's worth, I can't see how this is possible without effectively inventing a new form of physics. But I'm not the best person to pass comment. That said, there's nothing new under the Sun, so I very much doubt anyone has come up with a cabinet that has never been done before.

You simply make the horn length an odd multiple of 1/2 wavelengths at the crossover frequency of the driver front output to the horn output and the 2 outputs are in phase where it counts. That's old school info.
Everyone has a photographic memory. It's just that most are out of film.
