These days high-end loudspeakers are not seen with as much reverence as before, and the market is becoming dominated by their cheaper, more efficient counterparts. At the same time the demand for higher sound pressure levels is growing, which creates audible distortion problems.There are various DSP solutions for this, from tried-and-true fixed high pass filter, which, while getting rid of distortion, also cuts out a lot of bass frequencies, to complex new solutions based on physical models and adaptive signal processing.This paper proposes an approach that improves on the former while staying much less demanding than the latter in terms of computational power.
