Hi all, this looks like a nice place !I posted this info on another forum, but recent war centering on our buddy "Ed" pushed the post down quickly, and not many may have had an oportunity to see if this is of any use to them.
The link describes measurements and observations I made when trying to get extended top end from a horn, and some of the results seem contry to popular horn practise, so may be of interest to those seeking the same.
Cheers
