Convention Paper

Determination of the Thiele-Small Parameters Using Two-Channel FFT Analysis

Authors: Struck, Christopher J.

AES Convention 82 · Paper 2446 · March 1987

Abstract

The low-frequency performance of a driverfor use in a direct-radiator loudspeaker system is characterized by its Thiele-Small parameters. Two impedance measurements are required for the calculation of these parameters. A fast technique for performing the impedance measurements is presented and the calculation of the basic parameters is reviewed. Computer implementation for numerical calculation and control of the analyzer is discussed and the results for a typical driver are shown.
