Just do a search on Ebay. I also bought a pair of the original Time Windows at a local pawn shop. Asked DCM about parts and they never replied. These (mine) were a glued on clothe if I remember correctly. Not sure if your also has the center threaded rod to hold the top and bottom on, but you can get these rods at a place like home depot if you are interested in replacing the caps and yours has issues (as mine did). For the $75 bucks I paid for these speakers they sound pretty good. They are in use in my 12 year old sons bedroom.
