I agree with Martin - definately worth repairing. The S55's are some of my personal favourites amongst the smaller "S" series of speaker. Do as Martin suggests & replace the cap's in the crossovers while you have them open.
You won't find anything near as good as these, in terms of sound & build quality, for the price of a repair kit & a little work.
