Tractrix Horns Improved Imaging and Phasing Article

This article was written by Roy Delgado, Kerry Geist and Jim Hunter. At the time this article was written 1991 they worked at Klipsch in Hope, AR. This was to explain their transition to the tractrix horns. To see this much attention being given to Voigt is well deserved. This was due to Bruce Edgar for bringing Voigt back to the minds of speaker builders. I am lucky enough to have a pair of horns based off of Delgado and Klipsch designed Tractrix prototypes. They are wonderful. I hope you enjoy this article.
