The bass from the Odysseys cross at 250hz, correct? Being as I already have massive subs doing 80hz and below, I assume that I would probably notice a difference in the ML woofer.
I think I am leaning toward the 3.7i. I'm not sure how much more airiness I would notice from a stat over the true ribbon anyway.
Follow Ups:
And mix in your subs with high quality 'room correction'/bass management with measurements using DSP.
The type of algorithm is really important and some are much better than others. I know Anthem ARC is great, and people also seem to universally love Dirac & RoomPerfect. Also essential to limit max frequency of correction to 1000 Hz or less.
DrChaos,
My Marantz uses Audissey XT32 I believe. What is the consensus on that vs Dirac?
I think you should ask over at AVSForum, I think they are the experts on this. Though when I once read over there (a few years ago when I was looking around) there were reports from people who either liked or disliked Audessey's effects, but almost everyone liked Dirac or Anthem.
Dirac & Anthem do their estimation of the DSP correction with sophisticated software on a PC/tablet, and you have lots of control over the parameters & target curve etc. What does the Audessey system do? There may be a "pro installation" extra that would bring it up to that level but if it's only a receiver control then probably not.
If you can't limit the top frequency of correction then it's likely to have some negative effects on high resolution dipoles like any Magnepan.
I certainly heard it with Anthem ARC, correction up to its maximum (5kHz for my model) strangled some of the Maggie Magic in the highs, the transparency and immersion was lost and it sounded like a regular speaker. But limiting the top frequency had great results, the bass strength and smoothness was improved, as well as 'dynamic snap', as some of the subbass went to the subwoofer. Maggie panels have a bass resonance between 40-50 Hz usually, and there is some energy storage (less damping) there. If you can get that to a sub which has stronger damping (i.e. a SEALED sub) it sounded like a great benefit.
I couldn't get that without ARC, i.e. a plain crossover didn't do it.

That is what I found from their website.

Only to the extent that the ML woofer is covering fundamentals while the electrostatic panel covers the harmonics - albeit with a different character to these ears.
Ideally, you would use dipolar subs, but the more noticeable effect to me is what happens above - not below as the wavelengths are long and largely non-directional where subs play. I use a pair of subwoofers in the HT system supplementing Acoustat 1+1s crossed at 90 hz. That frequency was determined by exhaustive measured experimentation with various settings and placement in its space for the most linear results.
The big U-1s upstairs don't need no stinkin' subs. ;)
E-Stat,
I love the chart. I'm going to blow this up and frame it for my wall. Seriously.
