This is what Totem recommends for placing all their speakers, and it's worked very well for me:
positioning is very dependent and experimentation is the key
we recommend a systematic procedure where (with the same song track) you place the loudspeakers 1 foot from the back wall and do small increments forward until you reach the desired spacing
you should focus on bass extension, depth and decay
next place the units 4 feet apart and in small increments further the spacing between them
you should focus on imaging, soundstage and 3 dimensionality
