From the spec sheets, it looks a lot like the JBL 2226H. I'd start from there. Don't use the standard formula for Zobels, that's the way the old crossover was. I found that this design responds favorably to a smaller capacitor in the Zobel. Of course, I haven't tested with the 15M300, so there may be some differences but I would suggest starting out with the assumption that it acts similarly to the JBL 2226H and make changes if needed.
