![]() This system definitely worked better but it still had too much of the frying bacon sound at higher drive levels, I quickly came to dislike this characteristic after switching my own system to proper compression drivers. I remember there was a guy down the street with a Traynor or Peavey 2-way system, 15's with the big white horn something like the old Yamaha 4115 but with and separate super tweeter box on top with 8 or 10 piezo units in an arched horizontal array. Except for the later powerline compression driver versions these things were really only good for lower power levels. I still have some with holes burned through the piezo element from my first DJ cabs, after blowing these up twice in 2 gigs I substituted regular bullet super tweeters and gained a massive increase in sound quality, instead of everything sounding like frying bacon from moderate drive levels up I could actually discern the difference between ride and crash cymbals and the system had much better dynamic range. I used them in a few DIY projects of mine back in the '80s, for home audio apps they delivered a lot more topend than the cone tweeters that were common at the time but they didn't have the power handling capacity to survive PA applications in singles or even doubles. ![]() All of the original Motorola piezos were super tweeters and any type of deployment that didn't use them as such ended badly.
