Aimed at Turk 182 Earl. Maybe I came across a little harsh. I love a good constructive conversation

You have been very antagonistic to me in the past, I have to assume that this would continue. If, on the other hand, you want to have a civil dialog on distortion then that's fine, but if you return to the same old attacks then I will revert back to ignoring you.

What can I say about nonlinear distortion that I haven't already said 1000 times? It is not an issue for a modern competent loudspeaker design so why would I spend much time on this issue?

I am doing art exclusively these days.

point taken, and not meant to be antagonistic but if stained glass is your new thing why spend time on this forum?

with respect to distortion why do oblate spheroids suffer from such a high degree of amplitude modulation?

Could you show us what you mean by "high degree of amplitude modulation"?

can i show what i mean by high degree of amplitude modulation....all my attempts to record/ measure the effect with my limited equipment resources, no....but it's audible.


can you hear the results of shapes created with Ath4?

Then your question "why" doesn't have any sense, right? The proper question at the moment would be "what is it that I'm hearing in OS waveguides that I don't like?" And that's very difficult to answer - it can be anything, at least as long as the testing is not done blind.

- No, in fact I haven't heard any of these myself yet. Still in progress...

it's amplitude modulation, it's quite audible!

For an amplitude modulation to happen, there must be a nonlinearity. So which nonlinearity are you refering to? I don't believe there is a nonlinear behaviour in OS waveguides, or horns in general, that could be clearly audible. And if there was, OS waveguides should not suffer that much. How can you be so sure? I'm sorry but it sounds as a random impression to me. It still may be a linear distortion you are in fact hearing (and I'll give you that you really hear it) but that would mean there's still a lot of to be improved in the particular implementation. I've heard many OS waveguides and wouldn't ever speak of an "amplitude modulation". To me it allways sounded as clear as I could imagine regardless the sound level. YMMV, of course.
