Why not horns?

O. K. wiseass, you've alluded repeatedly to your 30 years of experience designing and building loudspeakers. It seems to be the justification for your opinions and the reason that we should feel subject to your authority. While more than a dozen of us have testified as to actual experience we have in owning and using our horns, you feel that your theories which you value so highly because of your thirty years of experience, thirty years of experience, thirty years of experience is superior to any personal testimonials any of us can issue.
Think about that. Doesn't it make you feel kinda foolish?

Before you bowl us over with more unsubstantiated nonsense about your vast thirty years of experience, try providing a resume. Duke and Ralph have very good credentials and a desire to remain impartial. I find them to be helpful. You come across meanwhile as a grandiose, self inflated, naysayer.

Herman, believe me, I have no desire or intention of getting into another worthless debate with you.

But you do force me to defend myself.
First, I never said that Thiel was the only time coherent speaker out there. Having owned Meadowlark as well as multiple pairs of Dunlavy I can safely say that time coherence is not something new to me. My assertion was simply that the exact speaker in question (Thiel) WAS time coherent and that "most" horns are not because "most horns" that I have encountered do not use first order crossovers.
Clearly, I do not know what YOUR speakers use. But when I look at the pictures of your system I appears to me that the upper horns are the Avantgarde Duo. If this is wrong please share. Yesterday I took apart a pair of Duo horns to see what was inside. On the (stock) pair that I looked at there was certainly more than a single capacitor going to the tweeter. I then measured the speaker and found I was correct in assuming that the Duo was not time coherent. The impulse response and step response clearly show that it is NOT.
THIS is why I said that (quote) "unless you changed the crossovers" neither are yours. I ALSO started off by asking what you meant by "time aligned". This, in other words, was the perfect opportunity for you to explain that indeed YOUR speakers use first order filters.
If indeed they do then they very well may be time coherent.

I am perfectly willing to accept this. But up to this point you have not indicated this is the case with your speakers. And time alignment is not the same as time coherent.

So, as I said. Please indulge the curious here (not only myself. I happen to know that Unsound is also a fan of time coherence).
Please go into more detail on YOUR speakers.
If you have a first order filter on tweeter. Great. What about the midrange and woofer? All three need to have minimum filters for the speaker to be truly time coherent. I am sure you know this. And I ask because I am truly curious. If your speakers use first order from top to bottom then you are only the second person I have come across to implement something that I have been exceedingly curious about for a very long time. Ie. horns+first order.

I am also very curious to know what woofers you are using. If your speakers did start life as an Avantgarde Duo, did you incorporate the stock woofer into your horn?

Thanks.

MacroTurd,

I'm sorry but you must have mistaken me for someone who gives a damn about your idiotic and abrasive rhetoric .

I guess you feel that Duke and Ralph won something ... LOL!
Please enjoy your distortionless speaker (your quote) Professor and get well soon...

Regards,

Ohhh,

In case you missed it Macroturd ..

You are pissing on your own thread , I'm sure Duke is proud to have such an ignoramous as you for a customer! with your vast wallet and big ears your listening room must appear to have a pr of horns on either end ...

Well I'm sure it's now your milkey tme ! Many Happies......

Herman,
I reread your most recent post. Good information. Thanks.
I'm curious. How exactly did you go about implementing a digital crossover without any phase shifts or time issues?
