If I were you I would look at up dating the crossover with better parts. The Maggie will transform in all areas. You find greater resolution, width and much deeper bass.
I have had many magnepans over the years and each one including the 3.6r was another speaker when the crossover was done. It is almost a crime to not do it.
Try Alpha core copper foil inductors and the best caps you can find. Mundorf silver in oil are great and not too expensive. If the caps get too out of hand try a good cheap cap and bypass it with as good a cap as you can afford. Most of the character will come from the bypass.
