I've always wanted some horns shaped like the curvaceous mudflap lass from days of yore;

Your neighbors called. They like your music.
Would you call those horns STRUMPETS?
Getting back to some earlier stuff in the thread - Magnavox horns.
I never cared much for them, but today I was doing some measuring of other horns and spied the Magnas on the shelf. Gave them a quick measure.
Not as bad as I thought! Fairly flat and distortion is low above 3K. Problem is, distortion skyrockets below 3KHz. That's why I had such a hard time mating them to a 12" driver, as they were originally intended.
But now I'm using them from about 5.5K up to fill in the top end and they sound quite nice. Not loud and splattery like before. I like them a lot up there. They roll off above about 14K. Nice tweeter, glad I didn't chuck 'em.![]()

They really are not a bad unit. Just the power handling is so low.
The Heppner version was a really popular DIY component.

Yeah I was kinda surprised at how nice they sound up high. Using them above 5K they sound rather nice - light and clean. Don't think I'll have much power trouble crossing up that high, but it's something I'll listen for.
A hidden gem. Glad I gave them another chance. Funny thing is, I would not have given them another chance, without measuring them.
As I recall from an interview Bruce Edgar did with PWK Heppner was bought by Klipsch who was at the time interested in the Heppner "dhorm" tweeter. According to DJK the small format horn-drivers used on some later Klipsches such as Cornwall IIs, Heresy IIs, Epics and KLFs are based on the Heppner horn and having seen some of those Klipsch horns and having been a DIY user of the Heppners in the 1970s I believe him.
