WMcD Posted January 5, 2008 Share Posted January 5, 2008 Attached is an article on horn design from 1928 by Hanna. You see this cited from time to time. It is interesting that comments by others, including Harvey Fletcher, appear at the end. Your weekend reading.

DrWho Posted January 6, 2008 Share Posted January 6, 2008 Wow, it's interesting what they knew way back in the 20's! It's also interesting some of the theories they had too, which can probably be better defined in later years. That was a pretty interested frequency response plot too...

ZAKO Posted January 8, 2008 Share Posted January 8, 2008 Mike...."Back in the 20,s"???? Well it was,nt in the dark ages...As far as I,m concerned its not that long ago.. Its classic textbook audio science..consider when tractrix was published. Just a blink of an eye. between the two. Quote Link to comment Share on other sites More sharing options...
