Vladimir- That's not really true, you really should NOT alter the signal going to the mids/highs in any way. Even a high end active crossover will add/remove artifacts from the signal and I have found it removes the overall musicality of the speakers(one of the main reasons I like these speakers so much). However if you were to make a simpler passive network only for the mids/highs and feed it a non-altered signal and use an active low pass crossover for the bass panel I think you would be on to something- though would it be worth it? Both Gladstone and I are bi-wiring our speakers and the improvement from doing that was tremendous! However, there are added costs and circumstances that make me not interested in bi-amping the speakers. For me I don't have the room to have 2 more mono-blocks, not to mention the desire for the added heat in the summer(my central air can hardly keep up as is). And I don't think Gladstone is going to be in a rush to pick up another set of Class Omicron mono's, for similar reasons.
He has been experimenting with a REL sub with superb results, he has it crossed over at 22hz and we spoke the other day about how EVERYTHING has gotten better. I am thinking about it, but right now I am so happy, why mess with anything :)
There are many ways to achieve an amazing system around maggies, but you've got to do a little work to get around there shortcomings. A lot of folks use active's and rave about the results, I know of a small handful who have done passives and raved about the results, and most who have tried both(who have a true reference quality system) prefer passive. There is also more flexibility to tune the sound to your liking with passives, a simple cascading bypass on your caps. and you can get a significantly different sound from using a different cap.
Now I am starting to ramble......... so I'll stop before I get carried away with myself :)
