Has anyone had a problem with a woofer on their Axiom speakers working their way loose. I had one of my M3s making a little noise but when I pressed the nuts for the woofer the noise went away. So I got a hex wrench and tighten all the screws and the noise went away. Should the nuts be tighten every so often after use. Is this a common problems. Any information is helpful.
