I am in process of building my next amplifier, and was heading towards a Lynn Olson Amity/Karna type. I currently run a set of ME-2 Ariels with a ST-70 and powered subwoofer.
I do not get enough midbass (100-500Hz) out of the ME-2's, and have read a number of articles (some written by Lynn) about what to do about this. Alas, not a simple solution.
My first preference is a passive linestage 6 dB filter for the ME-2's, with a separate midbass/bass driver. Attached is a possible attempt for the amplifier input.
It seems to me frequency-wise the filter would work, but if the components are not perfectly matched, which they won't be, the benefits of balanced topology are lost.
Is this a waste of time, or is it possible to get good performance if I attempt to match components? Like buy 10-20 capacitors and pick the best matches.
Better solutions?

Could certainly try that, but I have read a number of cautions about attempting to cap couple to transformers. Don't have any links to those cautions in front of me, but I do remember reading it.
Maybe it was at K&K, don't know. If it's really that simple why all the fuss about the difficulties in using active crossovers? Not talking 12/18/24 dB, of course.

With an 8" baffle width, that is likely baffle step loss... lots of ways to deal with that http://www.t-linespeakers.org/tech/bafflestep/intro-bds.html
Given my dislike for MTM... i'd look at building a bipole...
