Very interesting talk! Thank you for sharing! Would be cool to know how a Axi2050 compares to a Reference Driver when it comes down to intermodulation distortion, as far as I understand that is not easier to control when increasing the bandwidth a driver can reproduce. Any data on this?

what is KA=5 in this speach？

What you have done here is great, and sorely needed as I can think of only a few compression drives that can do what you are describing. However, you did it in the wrong material, since titanium dome is shunned by most horn enthusiasts because of its terrible breakup in comparison to Alu or Be dome diaphragms. If this feature of Ti as a material is still true when you wrinkle it the way you have done is unknown to me. But to call it wide band would be to fool the "audio pros" to continue with their use of the treble EQ boost button on their Behringer active crossovers to squeeze whatever is left above 10kHz of their poor titanium diaphragms, that causes me to hold my ears everytime I go to the cinema. Not that they would hear the breakups above 10kHz anyway, here the presentation explains a lot. Instead they should be taught to build properly sized multihorn setups. Then titanium is probably fine, as long as it doesn't go higher than 1500-2000 herz. Right now, most midrange compression drivers can't cover the frequency range that is the most sensitive to the human ear, starting at around 300Hz. Most wimp out at 500-600Hz, so this driver is a great contribution. Let's see how eager people are to put 100cm mouth horns in their cinemas and living rooms. I think this driver with a Tad-2001 or JBL with truextent diaphragm and possibly a Raal on top would be a great speaker. It would make 15" woofer almost tolerable as a midbass, if I didn't have to cross them as high as 500Hz.

((( I'm angry. That was a very low resolution video and you was successful to make a slideshow out of this.

I will never understand this
