AB  - When a loudspeaker system is driven close to its limit, Power Compression (PC) kicks in. Power Compression is due to heating of the voice coil and consequent increase of voice coil resistance: in PC range, an increment of voltage is not yielding a proportional increment of current anymore. The loudspeaker sensitivity changes. The tonal balance of a loudspeaker system, usually set for moderate signal operation, is supposed to change when it comes to large signal level, mostly due to power compression. Dynamic Equalization (DE) could be a useful tool to compensate for tonal balance modification: it is, in fact, a tool for equalizing an audio signal only under certain conditions of the input signal amplitude, for example when the input signal exceeds a predefined threshold. The paper describes the loudspeaker measurements and the consequent dynamic equalizer design and settings that have been done to accomplish this compensation.
