Physical and Perceptual Evaluation of Electric Guitar Loudspeakers
"Loudspeakers used in combination with electric guitars shall not only reproduce the electric signal captured by the pickup with low signal distortion, but the loudspeaker is part of the musical instrument and is allowed to shape the spectral components of the sound and to create new signal components as well. A combination of measurement, signal analysis, physical modelling, and listening test reveals the critical modal resonances, dominant nonlinearities, and other causes that generated the characteristic sound. This knowledge is required to optimize the design of the passive loudspeaker and to develop software algorithms that synthesize those distortions generating a desired artistic effect. This analysis is illustrated on a transducer used in many guitar loudspeakers."
