So My speakers started doing bumbling rumbling sound. It's not the connection, or the speakers (although it could be the woofer).
I have no idea what it is.

Thanks in advance

Have you changed anything in your setup to cause this?
And have they been working fine before hand?
It sounds either like a short or interference to be honest though

[Haun]

No, didnt move it, and it worked fine, we moved it to my room from the kitchen and still rumbled

[Haun]

it its a short, can i fix that at home?

[mctw]

Depends whats shorting and wear it is to be honest!
Have you tried using a different audio cable, and a different source (aka device that you plug into the speakers)

Just wondering, what Make/Model is your system? Might help me a bit, thats all!

Sounds more like a bad Xover or dodgy connection before amplification, most likely within the amp/avr than a short to me. Agreed on the interference though.

Check what input you've put it on, this sounds a lot like modern source in a 'phono' input, these were designed for use with record decks. Switch to Tuner or Aux.. Something like that.

Move it away from all other electrical devices, and spread out the speakers, amp or reciever and the source device as much as possible. Hell do it outside if you have to!

Then test it, if no joy, proceed
Swap out the source device for another product, if no luck, proceed
Swap out the amp or avr for another one, if no avail, proceed
Swap out the speakers for another set, if no difference, proceed
Swap out the cables for another load, if no delight, you're buggered!

Seriously after all that if it doesn't work. You must be electromagnetic or radiated.

PS
Like my synonyms?
