    Well when its at a certain volume then i hear it. its kinda like a buzzing noise, but everyone at my school says that its "cracking" and a friend of mine has the exact same problem with his too. ive looked at the speaker and it has no defects with it, its just that noise that it makes.

Yea i think what you are describing is a pinging/ringing noise. Attach new speakers like Bose to the system it goes away. Or just muffle the top tweeter with some kind of fabric between the grille and tweeter. It removes the pinging noise and the sound is much cleaner!

In regards to your speakers "cracking", It is an internal problem. It will soon say "protect" on the display if you keep using it and after some time it will shut off by itself. I had the same problem with my system and I called them and they said it is a bad resister. It is not an easy fix and you will have to send it in to get fixed.

It sounds to me like a ground fault. Try a ground reducer (you can get one at any hardware store, or radio shack for about 1 dollar) If it fixes it, get a good power conditioner (monster cable has a good one) if it is still there, then I would take it to a pro.

Im not sure as to your complaint?? Is it like a grumble? or a type of vibration?? if its only present when the low frequency is present then i woud say that you had a bad suround on your low frq type driver?? if this is not the case then i would look into a parimetric eq as this couls solve your mproblems.

    OK now that youve explained it a bit better its a componet thats starting to go bad as alot of solid state devices will do just before the go out they will start making noise like static type noises. The only thing you can doif your a technician is when this unit starts to do this noise spray a small amount of freeze spray on the suspected componet. Now it your not a tech there really isent much you can do as your gonna need the proper equipment to service these units but these systems have no user serviceable parts inside so my advice would be for you to take this unit into a repair shop for an estimate. Good Luck

We have a buzzing noise from our subwoofer. it's connected to a receiver, but the receiver is connected to a computer on a different floor. if we just use the regular radio it's fine, but if we listen to...


If it's source specific the problem would be with the source. Is the PC output sufficiently high that you don't have to crank the (unnamed) electronics amplifier volume up real high to listen to the PC? That would raise the noise floor.

Well,
It best to call the manufacturer to get the speaker system replaced. As you see it smell bad , could be a burnt fuse at the back of the sub.
