Default Proac 1S and 1SC crossover differences

Hi - was wondering if anyone had the schematic of the Proac 1SC crossover.

The problem is I have a pair of Proac 1S which have had the drivers upgraded to 1SC driver units (the ones with the copper phase unit) however the crossover has not been changed. I have talked to Proac they said the crossover needs some different values for the speaker to sound right with the driver upgrade There is a real problem with the sound of my speakers now, - there is too much treble and it definitely does not sound right.

Was just wondering if anyone has the schematics or knows what the differences between these two crossovers actually are. Then I could modify my crossovers myself.
