Positioning Magneplanars for Optimum Performance

I am in the midst of tweaking the room position of a pair of Tympani IVa's, which have two bass panels hinged together in a "V" and a separate midrange/tweeter panel on each side.

The only place I can really fit them is on the slightly longer wall of a squarish room, approx 24' x 27' with 12.5' ceilings and rounded corners.

Any input from Maggie owners would be greatly appreciated --especially from anyone who has owned or used Tympanis.

In the past, I have found that moving the panels closer to the rear wall seemed to muddy the imaging but increase the bass response. On occasions when the bass still seemed a bit thin, I found that moving my listening chair against the wall opposite the speakers also increased my perception of the bass response. But maybe this was just my room at the time.

I am wondering if I could keep the bass panels closer to the rear walls and move the mid/tweeter panel out into the room for airiness and imaging.

Especially taking the V shaped bass panels into consideration, would anyone have any rules of thumb or suggestions -- or is this just hopelessly speculative?

Thank you very much for your ideas and opinions.
