yah that room would be hell to calibrate, that pic is straight from Klipsch's website.
my room isnt much better with an L shape to it i can't put the surround speakers in the proper locations. Also my Front left speaker is near a hall way and i have the age old floor furnace to worry about. Anyone got any ideas how to isolate it from rattling? i have a Velodyne HGS-18 sub that is about 10 feet away and it rattles the floor furnace like crazy when i turn the volume up. Heck it rattles the windows in the garage on the other end of the house. I have Huge Spikes on the sub too.
