Previous works show the benefits of exciting loudspeakers with current sources, but they do not present a study showing the behavior of this technique when acoustic damping is applied to diverse types of loudspeakers. This work presents theoretical and practical analysis of the frequency response of acoustically damped current-driven loudspeakers installed in closed box, vented box and 4th and 6th orders band-pass systems. Also, it presents a subjective analysis comparing a closed box system excited by voltage and current sources.
