Determining Two-Port Parameters of Horn Drivers using only Electrical Measurements
The basic theory and a measurement procedure for the two-port description of horn drivers and horns was presented at the 111th AES Convention in New York, 2001 (Preprint 5409 "Two-port Representation of Horn Driver and Horn"). It was shown that this method is a powerful tool for the development of loudspeakers but it suffered from the restricted frequency range of the necessary acoustical impedance measurements with the Kundt's tube. A new method of measuring the driver's two-port parameters is presented here using only electrical measurements and an acoustical reference impedance. The frequency range of the two-port parameters could be extended using this method. The theoretical approach and first results are presented.
