It would be in Vintage Speakers/Schematics all except SDA but I don't see it. would say M5s or M5s rev2. I only see the M5b and the tl mod (SL3000) to the M5b, which would also work with the SL2500 but I doubt that is very close to the circuit you have.
You'll have to look at what you have and maybe we'll learn something, but inductors need a meter with more capability than the standard meter has, to measure.George / NJ

I'm pretty sure the M5b SL3000 schematic is the same as the one he has. The SL2500 has a large and small tab to connect to the wiring. The RD-0198 is a drop in replacement for the SL2500.
IF his crossover also has a 5.8uf cap across the resistor it's very likely it is the same. -

I guess we'll see. But if you look at the date in the SL3000mod for the 5B, I believe it is prior to the date that the M5 series II came out. Take the M10 schematics for example. The M10s rev2 schematic is dated March 1990 and the SL3000 mod is dated July 1989. The two schematics are significantly different.George / NJ

Remove the crossover, you'll find the values printed on the components.Political Correctness'.........defined

Sorry I don't have any crossover to look at. -
@CFarrell_SoundUnited In this case, since we replied to a thread that is in the wrong section, could you just move it to another section?
@JiLoq I see. So you bought speakers that someone had removed and sold the crossovers?
That's a predicament. You could probably copy the SL3000mod crossover then, if you can't get the crossover schematic from someone here. The exact Series II crossover would be preferable though.George / NJ

@JiLoq Here is the M7 Series II crossover that has the same active drivers. Of course, this speaker has a larger enclosure volume and therefore a different passive radiator but I wonder if the crossover was electronically the same as your M5 Series II.

If anyone is still looking, I took some photos of my M5 Series 2 crossover showing the Cap values. I also took the M7 Series 2 crossover schematic and modified it to show those 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.

More pictures coming soon for reference. I just acquired a pair of these.

These cleaned up nice. Might offer up these as a forum karma.

The design engineer is a personal friend of mine and I'll ask if he recalls the inductor values.Stan
