Does anyone know a way of dating jbl signature drivers by their serial #'s? I recently aquired a pair of LE 8's that have serial#s 7285 and 7284.Thanx for any help! allHere are a couple of shots of the LE 8's.Sorry about quality,but I am hurt'n for cert'n for a decent digital camera for my Mac.The numbers that are stamped on back of cones appears to be original with only reference to model,the #'s on both are LE 8 101.Whatcha think?
