Any good pointers for room treatments with maggies

Simon, I'll offer my observations as a 1.6qr. owner. I've added two kinds of treatment, both of which have improved sound quality. Without a doubt, the greatest inprovement came from installing four bass traps in the "plant shelf" areas on top of the two long opposing walls behind and in front of the speakers. This brought improvements equal to pretty major component upgrades. This treatment isn't Maggie specific, any setup would benefit in my room from the traps. The second tweak was installing DIY versions of Argents "Rooms Lens'" behind the speakers. These improved soundstage dimensionality and focus. You have to determine what your rooms' deficiencies are before proceding with sound treatment. If you head over to the Maggie User Group's website, you'll find all sorts of suggestions for different rooms and problems. It looks like many owners have rooms and setups that benefit from diffusion panels behind their speakers. Others resort to more decor friendly solutions like large plants behind their speakers for diffusion.

Simon,
I've got 1.6 QRs. In my old house, they were in a great room with cathedral ceilings and irregular room dimensions. No treatments, just great maggie sound. In my new house they are in a rectangular room with 8 ft ceilings. Yikes, purely awful sound! I went with Auralex panels floor to ceiling in the corners behind the speakers. That really improved things. It cost me about $90. I also tried the DIY room lenses, but they didn't seem to do much for me. Also tried some foam panels in the back corners but ended up removing them. Just a bit too dead, I thought. You've got to experiment quite a bit on this to get things optimized.

This first part I stole from a Frank Van Alstine post. Good wallpaper stores in large cities sell acoustic wall paper. Ask them to show you the sample book. You(or your spouse) can select the color or pattern. Applied acoustic wallpaper is reasonably priced.

This second part,I came up with by dumb luck. In my room,the sides are far away enough from the panels that they don't really need to be treated.

One of the best features(imo) of properly set up Maggies is the colorless(pitchless) reverberation that leads to imaging that is staggeringly good. Google Manfred Schroeder+colorless reverberation for more about that topic.

The rear firing sound waves,the ones that were causing colorless reverberation,were sympathetically vibrating the drywall,adding a ringing that I thought,at first,could have been the upstream electronics.

Adding acoustic wall paper to the wall behind the Maggie 1.6s improved their performance MORE than enough to justify the time and expense of adding the paper.

Maggies are a pain to set up properly,but once you get them right,you'll love them.

If you listen at rock and roll performance amplitude,you will want lots of watts.

Thanks for that guys,
the title is a bit of a screw up.
It's actually martin logan SL3's.
Now have the cara software and it seems to be adamant an asymmetrical set up will be best - it is a very odd room but this is the first time the siftware has suggested such a radical set up.
Tried it on my own and a few friends 'normal' speakers with very good results.
Could this be a vagary of panel speakers - I downloaded a file for the LS3s from the custom files so at least it has reasonably accurate info to go on.
Suppose I should just ask the people who make it

Now to produce a more solid 3d image and improve the soundstage.
This product addresses the top corner issues without sucking the life out of the system like those soft pillows.
Start with the corners behind the speakers. Then again in every corner.
