Hi djk
This is one of the examples of “prior art” cited in the patent and while it looks similar is not accomplishing the same things acoustically nor does it radiate what appears to be a single driver and many Synergy horns also appear to be a crossover less driver.If you don’t have a “facebook” account, you can watch Dr Jones video which goes into some of it’s operation here;

The design approach allows a much larger full range horn to be produced as well and those have caught on in the sports stadium area where the concert arrays would be used.
At this point, the J series synergy horns have been installed in half of the USA’s 100,000+ seat stadiums and many smaller ones.
These are VERY different sounding and much smaller and more powerful than the concert line arrays they have replaced, if you have headphones, here are a couple video’s which illustrate that;

Tom,
No offence, but the German product looks more like the Renkus Heinz design, and not yours.
Perhaps, but only until you examine how the drivers are mounted and how they work.
The ducts used in the prior art and their acoustic spacing prevent it from having the drivers combine to drive the horn passage as a single driver.
With the Synergy horn and earlier Unity horn, the drivers sum into what appears to be a single driver and in the Synergy horn, one can combine the outputs so that with a higher order passive crossover, they appear to have just one driver in the time domain as well. Try Doug's video on the face book page;

Why do you say expired?
