Ok!Do You have a high pass filter to try on the MG 3.6?
I tried a subwoofer that works well with electrostats and those were Audio Pro B2-50, but it did NOT blend in well with the MG3.6 at all.
I also tried woofer towers from my RS1-b.
It felt like strictly 2 speakers despite different frequency x-over settings.
Woofers fault maybe, I don't know. I had none other to test with.But testing my MG-MC1 with my Infiniy RS1-b woofer towers worked extremely well!
Albeit that the MG-MC1 have some serous issues regarding self resonance in membrane and major resonance in magnet plate, the sound was relatively good!
The one who succeeded was the one who didn't know it was impossible.

A stand alone high pass filter? No I don't. But as you know, with the REL it does have that - if I understand what you are asking... Speaking about Maggies have you heard the new line? The 3.7's in particular? I haven't and I know that we all are wondering what Magnepan has done to improve the crossovers etc... along with the other improvements. With my dedicated room (26 x 15 with 9' ceilings I have the room for 20.7's ... One should dream - right?
I think You would be quite OK with Your room with the 20.7.
Cheers!

That is a rather typical frequency plot of the 3.6.Well, the large peak at about 43 Hz will reduce the output from the rest of the bass driver. Removing it with a high pass filter will allow higher SPL. It will also clean up the midrange as there will be less "polution" from the bass section reaching it.

Sorry!
I passed my answer just after I got my e-mail call about an answer...
Using a high pass filter, usedin an active/passive confinement before the power amp, is the best way.
Roger Gustavsson is a good person to ask about this. (Sorry Roger if I put You in the spot here!)
But doing this will get rid of a lot of inductance and capacitance issues that the power amp otherwise have to cope with.
I have done this with my Apogee's with great success.
And yes, Apogee more or less advise You to do this to give You the best audio reproduction.
The result is MUCH more dynamics and clearance.
I never dared or tried this on my MG3.6 before I sold them.
Too bad, I think.
It would have given me some more "water on the wheel".
