speakers for a smaller listening room

I recently moved and managed to get a dedicated listening room (yay!), but its a little on the small side at 12 x11 feet. My current speakers are B&W CDM 9NT's, purchased when they were for a much larger room. Do i stand much chance of getting these to work well in a room this size? I currently have them 3 ft from the back wall, and about 2ft from the side walls, with the chair about 1ft from the back wall. The bass is pretty lumpy, and there's a lot of HF echo/clatter, i have some traps on the way to try and tame things, but are there any fundamental issues that would prevent a floor stander of that size working in such a small room? Any suggestions on position changes?

Thanks
Simon
