It's more than not being able to move a sufficient amount of air. The Gunned MMGs might be fine for playing a small group of performers, e.g., a single instrument or small ensemble (classical chamber music), one vocalist accompanied by a smallish band, but not when playing a large group such as a 100 piece symphony orchestra. In this latter case, the image is too congested,sounding too bunched up. I suppose that's also the "physics of it", too much information emanating from too few sq. inches of driver area, plus those drivers having to be placed too close to each other, even if to all be proportional. (IMHO if one is seated distant to the MMG it makes matters worse than if seated up front and close-by.)

... a 100 piece symphony orchestra. In this latter case, the image is too congested,sounding too bunched upI listen primarily to small jazz combos generally quintets or smaller although I also like contemporary big bands as well; and yes they do fine.
I will pull out large scale symphonies this weekend and give em' a go.
Magnepan certainly makes no apologies for any physical shortcomings of the MMGs; they practically admit these are merely the 'first crumb' leading into the dark audio forest where bigger and better things await.
I was listening last night and the realism and placement of instruments of these 'over achievers' of the Maggie fam are truly amazing. Certainly far beyond their $600 retail price would suggest. My only criticism is vocalist appear a bit short (instruments are fine). M3 Lover felt it was fine, I countered with I like the musicians,artist a bit higher as if they were on a 2 ft platform. His suggestion is to lean the panels to or fro although I'm thinking of simply lifting them a bit (ie on a small plinth like structure).

I found with my Gunned 1.6's there was a significant change in tonal balance with azimuthal angle, and this was not symmetrical left to right either. It was obviously audible moving my head in an arc about 1 to 1.5 feet from the tweeter.Hey GL, could you do a test for me on your Gunned MMG's?
Play something with a tonal balance concentrating around the crossover region. Could you try that experiment on your GMMG's, especially with pink noise? Do you hear that effect in the GMMG's?
The stock 1.6's and 3.6's were more normal in this respect.I even wondered if I got the wrong crossovers in the 1.6's but PG insisted it was impossible.
I also found that the G1.6's had great & lovely "toe tapping" midbass, which I attribute to the frames, but were 'off' on tonality for classical.
The issues I had were not readily audible with jazz and if that were my primary genre I would probably have kept them on account of the mid-bass but I ended up keeping 3.6s. I was running both side-by-side so I could make a close comparison. I think M3 heard them at my house.
Today, I use an Anthem MRX as a pre-amp to take advantage of its ARC correction & sub crossover, and the bass is cleaned up and snappier with the 3.6's.

I have a better idea Doc, come on over this weekend if your free and spend all the time you need on them. The house will be quiet.
They're still set up and aren't going anywhere soon. PM me and I'll give you the address.
I setup planars dead vertical and listen at the vertical middle of the driver, that provides exactly the image height you want. So both tilt and height would likely need adjustment to get you where you want to be.
