How to check Blown Speakers?

[Nicholas D. Davies]

Is it possible to tell whether you have damaged your speakers from driving
them too hard? I have a pair of AE109's and an AE107C and I'm sure they
aren't as loud as they used to be at the same dB volume level?

Is it just me, are they now worn a little, perhaps defective or have I blown
them? If I have blown them is there some way of checking this; perhaps
with some gadget from Tandy or a resistance meter? I only bought them a
year ago....

Thanks

Turn the volume right DOWN and put your ear next to each speaker
(each cone in each speaker).

They all should work. (obviously :-)

Listen for any distortion, crackling, buzzing, or unnatural colouration
of the sound.

If any of these exist (on various source material), you have probably
damaged a cone or two.

If one or more of the cones are not working, some speakers (very few)
have fuses in to prevent damage, check the book.

Simply, it could be the source, amps, crossovers, protection circuits
or cones at fault. (Or you ears :-)

Oh, first of all, check all the wiring!
