Convention Paper

Nonlinear Least Squares Estimation of Thiele-Small Parameters from Impedance Measurements

Authors: Waldman, Witold

AES Convention 94 · Paper 3511 · March 1993

Abstract

A technique for determining the Thiele-Small parameters of a loudspeaker driver using a single-impedance measurement of the driver when installed in a vented box is described. This technique utilizes nonlinear least squares optimization to estimate the components of the electrical equivalent circuit of a vented loudspeaker system, and can be applied to verify the tuning of the low-frequency alignment.
