MAC user needs 600hz round Tractrix horn profile.


Hi Guys,

I have a pair of P Audio SD-450s that I will be using with horn loaded PHL 3820s (actual horn design of the PHLs still pending and I may even jump up to PHL 12s) and would like to make a round Tractrix horn.

Because I am a MAC user I am unable to use the Hornresp program but looking at posts here it looks like it is able to render the horn profile.

I did find a formula on the net, and have been able to calculate the profile, however it only generates the profile based on the cutoff and takes no other information into account.

If someone here is willing to spend a little time and get it right I would be happy to PayPal them a few bucks (do let me know first).

Thanks in advance.
