Question

One of my floor standing speaks has recently stopped working. I think its likely to be a lose wire or something along those lines as it happened after transit. Im having troubles getting the speak apart, basically cant figure out how to do it. Ive removed the two screws (one at either end). But cant seem to get either end offHas anyone managed to get their speaker apart before? and if so how did you manage it?CheersKris
