Yeah, in many thousands sold, we have only seen one 70-20xr with a tear and that was due to a customer getting a belt buckle a bit to close to the ridiculously powerful magnets and it pulled the metal buckle into the tweeter. The 70-20 has a very unique design compared to all other RAAL tweeters and really any other true ribbon tweeter that prevents the ribbon diaphragm from tearing even under tremendous power and stress.
You are welcome to visit us anytime and we really hope you do soon!!!
