Dynaco, it depends on your tastes. Until this day, I have still not yet found speakers that have that "JBL" sound.
If you really enjoy the sound of your JBLs, have them repaired. Voice coil replacements would not be $500.00. Mine cost that much because I had the surrounds replaced at the same time.
Maybe $250.00? You would have to check.
Although, if your interested, I happen to know where there is a set of completely restored L112s w/stands that are absolutely perfect/gorgeous......
