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

usually make 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.


I can't speak to your specific repairs, but I have repaired speakers
for my car that had the broken rubber around the cone. The kit was
cheap and easy to install.

Simply Speakers.

Hi,
It all depends. What kinda speakers(music, instrument, size, etc.)
They all can be repaired. Voice coil can be re[placed, even impedance
changed. Cones replaced, ribbed or smooth cones, rubbers can be
redone,etc. I had a blown 15 in. keyboard amp speakers. I had it
repaired, recone, new voice coil, etc. for 80.00.
