No question about it. There is no formula for odd shaped rooms. Or much for any other rooms in my opinion. Research the Sumiko Master Set method. The speakers will "play the room". I've never found a better starting point. It was developed for hotel and meeting rooms for hi Fi conventions. Imagine how hard that is. If you spend the time and are careful you will be rewarded. Forget the tape measures, laser pointers, RS meters, hand clapping, and calculators.
