Those values are what I used, and I really liked the improvement. I think the sound is much more balanced.I have never used Auricaps or foil inductors so can't comment on them.
I think the larger cap values you saw were for folks who decided to try the MG12 crossover on the MMGs. I haven't tried this, but those who have have liked it. One comment I'll make is that it would place more demand on the tweeter, and perhaps make it more likely to burn it out. As far as I know, the new MMG tweeters are the same as those on the MG12, so it's not like it's wreckless to use the MG12 crossover IMO.
As far as the phase question, I'll bow out on that one.

Wow, two responses in less than 30 minutes! This is awesome. Thank you for the confirmation with respect to component values. I concur with your assessment that the additional capacitance would put a greater load on the tweeter; the modification I'm about to make will make is already going to increase the tweeter's role in sound reproduction. I guess the question is how much is safe?In any case, I think it makes sense to go forward with this upgrade and see (well, hear) if it solves the midrange problem these speakers exhibit.
