Big rooms tend to sound more 'even' since their fundamental modes are at lower frequencies, which means that in the mid-bass range the mode 'density' (from all the harmonics of the modes) is pretty high.
Maybe I'm not understanding what you're getting at here... but I've never, ever, ever
heard of someone designing a rectangular room using the golden ratio for listening
purposes. Every room I've seen that was designed to augment accurate reproduction of audio or minimize standing waves has used non parallel walls and ceiling/floor -- and often using curved surfaces as well to further minimize standing waves. But I'm certainly not an acoustician.
