Hey Gang:

My buddy comes over yesterday and tells me his center channel speaker was blown. His mom was turning on the system to watch TV, but no sound was coming out. Unfortunately, the wrong signal source was selected via his receiver. His mother then selected radio tuner as the source unfortunately the volume was cranked really, really high, and the source sound was garbled stactic highs.:eek: My buddy was pissed.

Now he says that the speaker performs the same in most frequencies, but on certain higher signals the speaker sounds crackly and distorted. Is this a sign to tell his speaker is blown? What would be a more definitive test?

Thanks...

    I'm thinking more of a crossover problem, due to the fact you state ok but on certain high signals.

    Can you swap the speaker in question with another one maybe a L or R speaker to prove?

    I'll suggest it...Why do you suspect crossover problem?

    Could it be a source problem? We had a discussion that certain source material isn't perfect...and you can hear it when it is less than optimal.

    Maybe the source it would be easier to swap the whole first so the center is the L or R speaker and the L or R speaker is the center speaker.

    Okay...I'll let him know...I guess you are taking out the suspected bad speaker...and replacing it with a known good speaker to make sure its the speaker? Can you fix the crossover problem? I'm thinking not.

    As a side...this has happened to me on my own system from time to time. It happened while playing Pirates of the Carribean during the Jack Sparrow escape scene, and a burned copy of Nora Jones...where the highs sounded distored.

    I had a problem similar to this when my youngest had cranked the volume and damaged a tweeter in one of my speakers.

    I checked to see if the crossovers were the problem first but it turned out to be in the tweeter's diaphram. One of the voice coils was shot.

    I don't know if this helps, but this is what I had to replace.
