thanks for the details. Even thoug it can't be qualified as true 
professional use it is already closer to that than the most common home 
situation. For me it is already really interesting to ear about the results.

Indeed a KlipschHorn is a good candidate for DRC usage. BTW, just for your 
information, there exists methods, based on Volterra Kernels, to compensate 
also for non linear distortion of speakers. There's a Studer paper on 
Internet about it. The math behind Volterra Kernels is frightening 
difficult, at least to me, so I never went through it.

Bye and thanks again,
