Thanks, starboy.
It is educational. Your Mantis might be an interesting cartridge and it is too bad that there is no way getting any frame of its performance besides buying it. Among the people I know, in whose listening rooms I was and why were and...

Jorge, that is good but a few thighs I would like to mention in this approach:
1) What you depict will work with tractrix or conical horn but not hyperbolic curve. The hyperbolic has own “swell” into exponential curve that would make it to...

I have never contacted Mr Andreoli but his fax number was passed onto me for a friend by Christian Rintelen of HiFi Scene magazine in Switzerland. Maybe the fax number is also Andreoli's 'phone number? Christian said that he is not online.

Outdoor performances always seem to me to fall short of indoor ones, and there are plenty of reasons why this should be so, but there is something attractive about a horn installation in a garden...it ought really to be made of rock, of course, f...

Here are some my ideas for an “Unlimited Turntable”. Feel free to share some of your ideas… An “Unlimited Turntable” should allow multiple arms. It should be a good quality arm with a good stereo cartridge…. Also, it should be a good quality arm with...

Lately I find my self listening in mono because of the area of my apartment and because I can focus better on the reproduction .

There were plenty it of them made: Techniques 9500, Excusive 2301, Iwatas, JBL 2350 and JBL 2345, Vitavox (narrow) and few others … They kind of very strange horns and I always was suspicions about them. Though my suspicions are purely theoretical: a...

Erik,
The high pressure zone near the throat does not create distortions; the distortions (the turbulence of the wave’s front) are created right after that zone (according to William Hall, MIT, 1932, though no one said hat he is right). Also, it is ...

Looking at the variety of exponential, parabolic, conical, tractrix, hyperbolic and whatever ales horn profiles out there I was thinking that we probably incorrectly approach the entire subject of horn profile analyses.
