One foot from the wall??? Say it isn't so. I assume since your room is 15' wide you mean the ATCs are 1 foot from the front wall. If you can I'd say get them at least 2 or 3 feet from the front wall and toe the speakers in a bit. A pair of Mana stands may also help. Also, make sure your listening chair is at least a couple feet from the back wall, as that will also reinforce bass at the listening position.
If all else fails, TacT room correction will certainly take care of the problem, and many others as well. Best of luck.
