Dd67000 crossover points?

@ptss Very interesting!!!

My speakers are flat to 30kHz, i wonder how much of that I’ve been experiencing??

I’ve also read positive things about damping ultrasonic resonances in tweeters during crossover design, but I thought that was because of distortion artifacts being introduced at a lower frequency.

Along the same lines, I wonder how much of our perception of music and sound is through our skin, and therefore how poorly our measurements may understand human perception.

That’s very interesting.  Can you share what some of those subjective comments were with and without the ultra tweeter?  I am curious how it was perceived.

@james633 . Thanks. I'll be looking into-for fun :)

@jc4659  from my post  AES preprint 3207 by Oohashi et al.  I didn't look into much detail - but it would be interesting for sure. As erik_squires mentioned, perhaps skin? 

I distinctly remember a very unique "sensation" - that was more than sound- when going into a Jazz venue in Seattle back in early 80's.  Big venue, high ceilings, horns and cymbals full tilt. Exciting.  Perhaps Erik is right- skin picks up those ethereal sounds. Magic :)
