info on AR speakers

Helping an old friend recently move some furniture, I stumbled on to a pair of AR-2ax speakers. They were being used as lamp tables. I was told if I carted them both out their mine. I am playing them at the moment and very surprised while listening to some Sonny Rollins & a Decca recording of Aida. They the recordings sound full and large in there presentation making trumpets sound large with good dynamics and Sonny's sax sounds rounder then usual. I like to know if any members have experience using them and I would like to change the cloth on the grills which is now rather rotting and yellowed with age. Also the best stand for this speaker? I am using a pair of 12" Metal stands and wondering what the best height and how far close or away from the wall? I thank all..
