Not sure if anyone on this thread invest in high end car audio along with high end home audio. If I didn’t see you at an IASCA Car Audio Sound Quality Championship (top 20 individuals), I’m sure you didn’t invest that much in that field. I won’t have the time to educate you on how some home audio products come from car audio. Example, JL Audio, Straightwire, and Focal Utopia BE to name a few. Pure Beryllium Inverted Dome Tweeter was Designed to be used in Car Audio to drown out engine noise in most Italian and German vehicles. They created massive feedback due to how the ground wire was routed and various ECU/ Computers in these vehicles. American vehicles don’t suffer the same consequences back in the day. I have been involved in high end audio for home as well as high end car audio since 1988. I’ve had the pleasure of experimenting with quite a few tweeter and crossover application. I was very fortunate to experience this. With tweeters of this magnitude, it really depends on your complete setup (amps, CD Players, preamps, speaker wires, etc). For car audio and even some home audio application, it was a bit bright for me but I did have the pleasure of utilizing the Pure Beryllium Inverted Dome Tweeter in several applications.
