This workshop presents measurement methods used to characterize loudspeaker performance at large signal levels. A brief discussion of each technique; how it evolved, what benefit it brings, etc. will be followed by a demonstration of the technique where possible. The discussion will include: High power impedance measurement, Xmax, Model parameter nonlinearities, Flux modulation, Harmonic Distortion, Maximum SPL, and Power compression.
