Re: Subwoofer smelled like smoke, fuse or voice coil...
DON'T PRY IT OPEN! EVER! Just take it to radio shack and they will be able to do a visual and possible expert evaluation for free and them tell you what they suggest. Too complex to descrive on the internet. Plus you shouldn't try to do anything by yourself even with instruction.

one set is for the subwoofer itself and the other is for the tweeters or the voice coil you will see this a lot in car audio just find which ones which and dont put a lot of power to tweeter/voice coil
> I turn the volume to a low it still has the odd noise
If there is any drive to the speaker at all (volume not turned off), the rattle is probably coming from a broken 'surround;' the part that keeps the cone centered around the outer edge.
Another point of failure is a structure called a 'spider' that is located between the voice coil and cone that ensures the voice coil stays centered.
If there is hum with the volume turned completely down, the amplifier driving the speakers (internal or external) has a failing filter in the power supply.
Since this set is hardwired together and the other speakers are working, the only easy fix would be the subwoofer got turned down on the remote volume control. Anything more would mean its broken. If its under warranty take it back. If its not and you know somebody capable, you might have them check for the obvious,bad solder connections on speaker, or and open voice coil on the speaker it self.
a usual problem of a subwoofer just like my old sound system. Subwoofer generates a big heat on its device unlike ordinary speakers. better to send that to a technician to change a spare parts. it must be an ic problem got damage by over using.
switch your subwoofer off from the socket for at least 30 minutes and check if the noise is still there,if its still there open it and play a movie then press it lower if the sound stops then you will have to put some toilet papers at the back of it ,thats what I did to mine.
this is just a shot in the dark, but have you attempted to play around with your sound driver's configuration? I'm unfamiliar with the newer Nforce stuff, but try looking around in the sound manager Nvidia uses. It sounds like it's been configured to swap speakers. (As an example, I'm using the realtek audio manager on an asus p5k-vm board myself, and the option shows up as "Swap Center/ Subwoofer Output" in my configuration.)
You blew the amplifier in the speakers. If you are an electronics hobbyist and have some time you can probably fix it, otherwise they are not economically repairable.
Probably not what you wanted to hear but the fact is PC speakers are fairly inexpensive these days and used units can be picked up even cheaper.
