Those speakers were not designed nor licensed by Richard Modafferi.They have their own patents, but the circuit described is essentially similar what we used in the earliest generation of our products. The only difference is that they moved a series element from the hot side to the ground side. In my opinion, if someone were to challenge their patents on that crossover, one could easily show prior art by EA & JSE. They were very clever to describe their slopes as 50-60 dB per Half-octave instead of 100 dB per octave, which might have set off some red flags for the patent examiner, who, in my opinion, goofed on allowing this.
Besides, we've moved on to a newer hybrid version of the Infinite Slope network, and it works better all the way 'round. So why fight over the older technology?
