Convention Paper

An Acoustic Model of the Tapped Horn Loudspeaker

Authors: Berzborn, Marco; Smithers, Michael

AES Convention 145 · Paper 10047 · October 2018

Abstract

A lumped-parameter model of the Tapped Horn loudspeaker–a design where the loudspeaker driver radiates into the throat as well as the mouth of the horn simultaneously–is presented. The model enables the estimation of the far-field sound pressure response from the Thiele/Small parameters of the loudspeaker driver and an additional analytic two-port matrix representation of the Tapped Horn. Simulations, performed using the model for subwoofers, are compared to measurements from an actual loudspeaker.
