Talk about rewriting history. I said that steep crossovers can't totally CORRECT dispersion
errors. One is in the frequency domain; the other in the polar domain.
WHAT?!? Talk about EGO. Kim is an engineer and clearly knew about "ringing". You asked him about it and he explained it to you. He was asked about it on DEQX forum long before that and when you brought it up, I explained that I remember something coming up about it and Kim explaining that it exists, but acoustically cancels, at least in the horizontal axis.
I'm refering to the fact that I wrote an e-mail to Kim Ryrie explaining why it DIDN'T
acoustically cancel; and I received a reply for Kim Ryrie that I was CORRECT - it
DOESN'T acoustically cancel. John Atkinson's measurements also reflect this.
If it "acoustically cancels"; how did JA's microphones pick it up?
I believe I posted Kim Ryrie's reply that I was correct in one of our previous discussions.
If you knew this as well as you think you do - then you'd be up to speed on this.
You understand math, you just don't understand audio very well. Want to go over your incredible "half-wavelength" theory on proper placement of dipoles again, Mr Brainiac?
Audio is physics and physics can be expressed in terms of math.
The "half-wavelength" discussion is correct. If you had the mathematics background, you'd
understand that. If you've improved your mathematical acuity in the mean time, I can explain
it to you again.
You didn't catch the flaw, it was already known and discussed long before our argument over how steep crossovers function.
I recall that at the time you were expounding as to how the Xd was "perfect" and that there
weren't any flaws - that I just didn't understand how they work.
Now you say that you, or at least somebody; knew about the flaws all the time.
Which is it?
BTW, I had a chance recently to hear the NHT Xd again in San Jose.
It exaggerated the size of the image of the female vocalist; that or somewhere on this planet
is a female vocalist with a 4 foot wide mouth. Dispersion for dispersion's sake is not a good
design principle; it must be tempered.
