Klippel LSI — Large-Signal Parameters

Why large-signal testing matters

At higher amplitudes, loudspeakers produce substantial distortion in the output signal, generated by nonlinearities inherent in the transducer. The dominant nonlinear distortions are predictable and are closely related to the general principle, particular design, material properties, and assembly techniques of the transducer.

What the analyzer reveals

The Klippel Distortion Analyzer combines nonlinear measurement techniques with elaborate computer simulation to explain the generation of nonlinear distortions, identify their physical causes, and give suggestions for constructional improvements. Better insight into the nonlinear mechanisms makes it possible to further optimize the transducer with respect to sound quality, weight, size, and cost.

What the test delivers

The LSI test identifies peak displacement (Xmax for BL, compliance, and inductance), provides more accurate prediction of parameters at working levels, shows the relative balance of magnetic and mechanical nonlinearities, and gives a good approximation of thermal limits.
