One thing that surprised me recently was that low frequency waves didn't seem to care much for my spindly little internal walls, and only the solid external walls really seemed to contribute to standing wave formation. That might turn out to be good in your case, although I imagine that doing a good job on soundproofing would make your walls have a greater effect on standing waves.

Any chance you could post a floorplan pic ? Not just the room, but the entire floor including exterior walls. I have this crazy idea that you should soundproof three of the walls and leave one untreated so your room *acts* rectangular even if it's actually square.

Without naming names, there are some frequent posters here with square rooms who might be able to offer more useful advice than me.
