how old could my m60ti's be? if they were the oldest? are there different versions released? if so, how can i tell what version i have? any ideas? i ask, because these speakers i ahve look BRAND NEW...and not at all used. so i was thinking that maybe they ARE pretty much new. just wondering if there is a way to find out. a manufacture date or something...or version number etc. TIA
