10a placement in a small room?

First of all - Great Forum! The knowledge and experience evident in the 300 or so posts I've already read (in one day) is invaluable!

After 20 years of missing the Monitor 4's I had as a teenager, I finally started looking for some vintage polks. Picked up a pair of PRISTINE 10a's off CL for a meager $40.00!! They have the peerless tweeters and the drivers, boxes and grills look great. They sound great too, but I have them in a small 12x13 room and they are only about 5 feet apart and sitting on the ground. The imaging and sound field are OK, but not as good as I remember with the 4's. I've moved them around as much as the space permits, but can't get that sweet sound I remember. Is my room just too small, will stands help, what suggestions do you have for my situation?
