I noticed that there is no published crossover schematic for this speaker. I had mine apart recently so I took photos of the capacitors and made up the crossover schematic. I took the M7 Series 2 crossover schematic and modified it to show these values. The only difference I can see is the C2 cap values. I don’t know what the inductor coil values are, but I suppose they would be the same or very close to the M7 values.

    This schematic is similar with slightly different values in the tweeter network

    VR3 I believe that is for the 5B.

    I recently picked up a nice pair of Monitor 7 series 2. ZSP told me the laminated core inductor was a cost saving measure that he was able to get to sound good but recommended replacing it with an air core inductor. I see the Monitor 5 series used the laminated also. Next time I see him I'll ask if he remembers if the M5 uses the same value as the M7.

  • CORRECTION….

    The first diagram at the top of this pos has a note that incorrectly says that the tweeter is wired in reverse phase. I incorrectly assumed the small terminal on the SL2500 was negative.

    Here is the diagram without that note.
