Regarding the center image, you will probably have to spend some time dampening the back wall behind the speaker to get the center image you're looking for but with some work, you will get there. It will not be monitor type pinpoint imaging but that's the trade off with panel dipoles.

Not heard open baffles so cannot comment on those. I had Maggie IIIa's and ML Monolith IIIx and biamped both of them. The former used a passive xover while the latter's was active. The ML model you are looking at is essentially a biamped speaker.

I had the Maggie's for 3 years and replaced them with the Monoliths which I had for nines years before leaving them in storage when I went overseas. I listen to mainly rock and blues, some jazz and classical. Back then, mainly records. Bryston 4b on the woofers and Audio Research D125, then VAC PA160 monoblocks on the panels.

These would playing quite loud and without distortion. Was there discontinuity between the panel and the woofer? You could eliminate most of these by using the xover controls and selection of amps for the woofer and panel. I am sure that this is well addressed in the model you are looking at currently. Also, I ran the VACs in triode where they put out on a good day 70 tube watts and yet they could make those panels move air and cleanly. Further, the panels back then had a nasty dip in their impedance down to 1ohm or less if I recall and all that has been remedied so amp selection is quite wide. My room is similar to yours at 12x25 with a 12' ceiling.

I am currently using cone speakers, Sonus Faber Cremona floorstanders, a different speaker entirely. My wife loves the looks of the Cremona's but I'm still thinking about going back to another ML product or Maggie 3.7s. I have nothing but good things to say about ML products and customer service.
