I have a set of B-2 shelve speakers, I noticed that the bottom speaker (bass) is not working at all there is no sound coming from it. I haveplayed with the wires the balance and bass adjustments. I still have no sound is my speaker blown? The top speaker is working (tremble). THought maybe there is a fuss or something. Usually when a speaker is blown is sounds distorted, this has no sound at all. Can anyone help?
