Perhaps one of you have a schematic for Canton's black box RC1 (equalizer for the passive loudspeaker ERGO RCL) so as a schematic of the passive crossover network - thank you very much

Hi Tiefbassuebertr,

some years ago I`ve owned the Canton RCS which come with a very similar EQ-Box. I`ve analyzed the circuit. Basically it is a parametric EQ with fixed Parameters like center frequency, bandwith and boost/cut for 4 or 5 filter-elements. Low frequency EQ has been done by an active highpass filter of 4th order tuned to the chassis and the enclosure requirements. If you are interested in the details of the RCS I could search for my old documents and see what`s still there.


Regards, Jürgen
