Re: MMG Crossover Upgrade (yeah, another one)

Thank you for the suggestion. The only drawing of the MG12 schematic I've found doesn't appear to be authored by Magnepan. In your second upgrade, did you use a 2.8mH inductor (and of what design)? The higher capacitance is easily obtainable by paralleling additional caps. Also, did you use a low value bypass cap in the high end section (and, if so, have you tried the speaker without it)? Let's just say that I'm curious how a cap that operates so far beyond audible frequencies can really "clean up" the sound (kind of reminds me of Monster Cable's "directional" wires - folks, we ain't listening to DC). Hey, as I mentioned in my initial post, I could be "all wet"!
