I still have a headache from those in the Disco Days.
I believe it was in an old issue of the HiFi Critic, a Disney sound engineer submitted plans for building his version of a speaker. It was quite large. He used only JBL drivers and horns and went on to say that they made some of the the best drivers in the business but couldn't do the crossovers correctly. It was tri-amped as well.

Who's to say?
