Default Help With Existing Crossover Points

I went active with my setup and need to know the crossover points in this design. Can anyone please help?

If I was a guessing man I would say 900 and 3.2k but I know theres alot of smart people on this forum that can tell by the values.

Thanks in advance, I appreciate any help I can get.

Got LTspice? It's free. I'd put the schematics in, replacing the drivers with resistors of the rated impedance (or get really fancy and make some sort of speaker model out of R-L-C), and let the resulting AC sweep graphs tell the story.

But offhand, looking at the graphs of the midrange polarity reversed, I agree with your frequencies.
