Post Subject: Tractrix for LFPosted by guy sergeant on: 8/6/2007
Hi Jessie.
I haven't built anything like the project you are attempting although I have thought about such things. Sadly I don't have the space either! i'd definitely be interested in coming to hear it when its completed & working satisfactorily.
One issue that I would consider is that the Tractrix profile supposedly does not lend itself aswell to extremely low frequency horns (being too short) as other profiles in particular the Hypex (Salmon) shape. I was wondering whether it was actually possible to add an element to the tractrix formula which lengthens the horn expansion in the way that a T value of 0.5 or 0.6 does to a conventional exponential expansion and therefore obtain an LF response that gets closer to the theoretical Horn cut-off frequency than the tractrix expansion might normally allow.
