Call Bill at Millersound (215) 412-7700. He is speaker repairman extraordinaire and used to sell Mordaunt Shorts and probably can tell you what to do. If you would care to send the speakers into him (outside Philadelphia), he will make them sound even better than the original.
Tell him Vinh Vu sent you.
Good Luck.
