I disagree. You just have to think vertically. I had the same issue - not enough floor space to accommodate a pair of subs. So, I built frames which place each MMG above a 10", sealed sub. I can't convey how excellent that arrangement is. I don't hear 'subs'. I just hear MMGs that are solidly full-range. I'm confident that I have the world's best MMGs! ;-)

Wazoo,
I sure would love to see a picture or a description of how you elevated your MMG's up over the subs.
Concern about the sub boxes vibrating the Maggie panels sounds right to me.
I am accumulating stuff to build a pair of dipole subs (a la Gradient for the Quad ESL 63) but elevating the Maggies has me stumped.
Mine are SMGcs that have been "Quasi-Gunned" with heavy wooden bases. I had planned to just spike them to the tops of the sub, but maybe there is a better way.
Thanks,
Louis
Here are a couple of photos. First, here's a shot of the ugly side - from several years ago. The wires entering the XO enclosure are off center because I originally kept Magnepan's plate (not any of the hardware, just the plate), hence the screw holes. Eh, it's the back, which faces the wall. ;-)
From the front, I think they look rather nice. Yeah, I know they aren't exactly in the greatest setup, but they sound fantastic anyway - very nearfield, in a bedroom (the smallest one in the house and it's still a bed room).
Thanks for the pix...way purtier than mine will be... :)
Mine will be only 12" or so tall and horizontal.
Similar to the link below (I hope)
LOL! I agree...in fact, I had wanted to do this eventually. I certainly noted your smart approach since the days I first came to the forum.
Long story short but a few minor things all added up to it being not practical here for now. One actually added up to outright unhealthy, as in WAF-nuclear. The amount of daylight already being blocked by the system makes the room too dark now. Sure, the TV doesn't help. The net result is that the nice view of the park, behind our apartment, is then fully eclipsed.
...I'm merely an imitator, not an innovator. Shortly after getting my MMGs, the thought of converting them to hybrids (like I've seen from Acoustat, Martin Logan, or...) began ruminating in my head. The only thing I did which was at all creative was build my frames such that they straddle the subs, rather than integrating the subs into their structure. Part of that was motivated by a desire to isolate the panels from any vibrations the subs could impart (probably, not even necessary), but it was also in the interest of sub replacement if one ever went south (and I couldn't repair it). Of course, I didn't address the second issue very well at all, because it's bloody tough to find another 10", sealed sub with the same (or smaller) footprint as REL's Q150.
Oh well, live and learn. :-)
In terms of WAF, the stereo got booted out of the living room. My MMGs are now in a bedroom and my wife supported the idea of a mancave for a big rig. We don't have much of a view out of any of our windows. ;-)
