That's the front wall; the back wall is the one behind your head. Mine are 30 inches from the front wall.
How far from the back wall are your speakers?
I like very much the sound from my Totem Staff speakers, although the are 4 ft 4 in from the back wall, a little far into the room than the suggestion from Totem. Just how far are your speakers from the back wall? My lisening room is 10 ft wide by 17 ft long.
