Convention Paper

Loudspeakers' Electric Models for Study of the Efforts in Audio Power Amplifiers

Authors: Bortoni, Rosalfonso; Sette Silva, Homero

AES Convention 115 · Paper 5911 · October 2003

Abstract

This work presents electric models for loudspeakers installed on baffles and enclosures, as closed box, bass-reflex, 4th and 6th orders band-pass enclosures, using passive crossovers from two way to three way, whose impedance curves were derived from MATLAB' simulations. The impedance curves, it's module and phase, are presented for each one of the cited models above. The transfer functions are also presented, besides the necessary considerations to get the results from the loudspeakers specifications, dimensions and box tuning. Examples of the efforts caused in the output stages of audio power amplifiers are presented and commented.
