Google -RoyC. AR dope-, then decide whether you would like to try and find/purchase some (if it's still available).
In the meantime do not put anything on the surrounds.

speaker cone doping?
I found a wonderful pair of AR-2ax speakers in very good condition at a friends apt used as lamp stands. I have them at the moment and enjoy there ease that it takes to drive them. I noticed the bass drives are made of paper and wondering because of age would it make sense to dope them using a solution of thinned out white glue to stiffen them? Is this mod still being done and wondering will it help the sound in anyway? Thanks
