The π wood tweeter is a radial horn, with straight side walls that set a constant 90° horizontal pattern. The throat is shaped so that constant directivity is maintained all the way through the top octave, not just to 8-10kHz like some other CD designs. The top and bottom walls are curved, providing smoothly narrowing directivity in the vertical plane. The final flare on all walls transitions to a tractrix curve with mouth angle widening all the way to 180°. It is also curved deliciously on the outside of the flare, making it probably the best looking wood tweeter horn I've ever seen. Come see and hear it at LSAF 2007!
