Oy my second quad speaker has a worse problem ..

Well, UPS showed up with my second speaker...all I get out of it is an electric/static sound....Any ideas as what could have happened? It makes that noise with speaker leads or not connected....and both channels in the amp are good.
Any ideas?
Not connected?!?! I assume electric/static noise is hum or buzz.
the speakers went back and i am getting a different pair..
Another stellar product from Red China.
