Oh well.. I'd really like to save the horns. I appreciate your offer to help out!
Still no measurements, but this can start the trouble shooting...
CONSTRUCTION
First I refreshed my memory of exactly what I built. They certainly are far from being copies.
I cut the horn where the throat dia is 5.6" instead of 4".
The idea was to extend it (6 inches) to make the throat 4" only if it didn't turn out well. I hadn't expected such big problems with the sound though.
Exact details are in this post: http://www.goodsoundclub.com/TreeItem.aspx?PostID=1807#1807
PROBLEM
It sounds like hard clipping on tones around 1kHz or something.
Even my camera microphone catches it easily.
Listen in headphones and compare the first two tones with the rest: http://www.webbtjanst.se/temp/horn_piano.avi
The two distorting tones are repeated at the beginning of each bar.
It's only the right horn that's playing, without back chamber.
Some photos.
The beginning of the throat is little wider than planned, but only for the first millimeters.Rerurn to Romy the Cat's Site
