May sound stupid -

But does that mean, the speaker does not rumble, make any noise whats so ever?

A buddy gave me his speaker, connected it to my home stereo, and not 1 noise.

Thinking it could be fried, but no physical damage on the speaker(cone/magnet).

 

Most fried speakers don't appear to be physically damaged. It's the internal voice coil that gets fried. It's like a heater element. Too much current passing through the voice coil for too long (especially in one direction) will overheat and damage it, making it totally useless. It is fried, not blown (like a busted cone).

This is all assuming you have the right setup. Obviously, if you're trying to drive a gigantic 2500W subwoofer with a 5W home stereo amp, you're not going to hear anything.

 

Thanks lowdrive.

A buddy also posted this,

"use your multimeter to see what the coil resistamce is at the "rest" state. 4 ohm speaker should be around 3.2 ohms or so.

If you get nothing (infinity) then either one of the leads are snapped the coil has heated up and crapped out."

 

I guess my next question is, if it is Fried, is it worth repairing?

 

Depends on what kind of speaker it is. Alot of high-end speakers can be re-built. But if a cheap brand your better off buying a new one. The cost will be more then or about at the same price of a new one.

 

#1 before you go and get technical with testing with a meter and ****...SMELL IT!
if it smells funny you prolly fried the VC.

double check the tinsel leads on the back of the speaker itself.
the tinsel leads are the spots on the back of the speaker where you hook your wires from your source.

most of the time it's a relatively easy fix if it is in fact broken there. but just like wrx-killer-Sti eater stated...it might not be worth it if it's a cheap speaker.

you still have yet to tell us what model, size, and manufacturer this speaker is.
