Andrew is not a fan of measurements.
Judging from various interviews and presentations, I would assume he is a fan of extensive measurements. But rather early on, in the design process of drivers, for example. He has just claimed he would not let measurements have the final say, in case things don´t sound right (think he mentioned that in some public interview at a trade show, was it with JA?)..
I don’t believe they have done much development into it as they didn’t know if it was a coaxial compression driver yet or if it was a standard driver.
Did you talk to AJ? Would be surprised if he used a compression driver. He usually relies on bigger dome tweeters in coaxials meant for higher SPL reserves (R1, V10).
. You are right, perspective is all wrong, so something seems to be off.
