I just got a new Eden CXM-110 and plugged it in and at low frequecies there is a rattle that comes from the speaker. Not there at higher frequencies. I tried different basses and amps with the same rattle there when playing the B and E strings. I e-mailed Bass Central where I bought it and they told me to contact Eden. They won't return my calls or e-mails. The Eden phone person said "Earl is too busy to talk on the phone" With no one willing to help I took matters in to my own hands and at first thought I had found it. The grille had gotten pushed in/kicked at the lower right corner so that it was touching the speaker housing. I took it off, bent it back, thought I was so smart and, of course, it still rattles. When the bass is rolled off or the volume very low, it's gone. Any medium volume and low frequency dialed in and the rattle is there. It is less perceptible at higher volumes as I think the speaker volume drowns out the rattle, i.e. the rattle sound does not increase with increased volume. Anyone have any ideas?
