I've got a lot of big, small and medium speakers that have blown out over

pretty good bookshelf supports.



In the spirit of domestic harmony, I am cleaning out said attic (anyone

*really* refer to their old college texts or books they have read in the

past anymore?). So with all the books being "de-accessioned"

(librarian-speak for "thrown out") I am left with a lot of bowed knotty pine

planks and burned out speakers.



If they can be salvaged, I can use them, but if they're likely to just blow

out again, I will send them to the curb monster that comes by late at night

before trash day.



So my question is this. Is it worth repairing 10 or 20 year old speakers?

Can replacements be readily had?



Is there a good site for diagnosing speaker problems? I almost always

assume it's a fine wire winding in the voice coil that shorted when a

speaker no longer even responds to a battery "click" test but I that's an

assumption.



Is it possible to match the characteristics of the old speakers closely

enough without manufacturer info like a parts list?



Do crossover networks ever go bad? Can they be tested with a multimeter?



And yes, I googled it,



http://www.google.com/search?q=diagn...ms&btnG=Search



but I didn't like very many of the sites it revealed. I'll keep searching

but Google ain't what she used to be.



Hmm, should have added "blown" to the search term - much better. Still not

great, though.



Thanks in advance for your input.
