"blown speakers"

When a speaker "blows" what actually happens. I suppose its different between a tweeter and woofer, but is there some mechanical damage or is it electrical. does something break? Besides a woofer cone ripping, what happens to a tweeter if it is still working, but raspy or staticy? I have heard "blown" speakers before, or ones that didnt work at all, but I really dont know what it is that breaks and whether it is fixable or just replace.

Is it rasping or is there no sound at all from the woofers?

Play a test tone CD.

Either your drivers are damaged or something's failed in the crossover, yeah.

Manitunc, at this point, you need to remove 1 of the dead woofers and test it individually. If that works, you are on the right track with a crossover repair. I didn't see anywhere, did you say what speakers you have?

the crossover is not viewable or easily accessible. I will be taking it in to a dealer today to see if they have the tools to open it up. I cant imagine it would be a fuse that would not be accessible to the user. there is no sound at all from any of the three woofers in that speaker, but the midrange and treble work fine.

You could take a driver out 1 at a time and using a DVM measure the resistance of the speaker at the speakers terminals;maybe one is open and if they are wired in series then all the drivers would appear to be non operational.
