Hey guys I changed the speaker of my Ampeg B-15N a few months ago and it recently started to rattle pretty bad. It was working fine for a few months until now. The issue is that now that the driver is worked in and looser, it rattles against the bar that crosses the middle of the baffle hole. Seems like the speaker foam seal that touches the baffle is too thin to keep the cone from hitting the baffle. I confirmed this by loosening the speaker, playing a note and then gently pushing the speaker into place. The noise is only present when I push the speaker in place. I put the speaker that came with the cab (Realistic 40-1318) that has thicker foam seal and now the issue is gone. Has anyone experienced this issue before? If so, how do I fix it? I really like the 15A and would like to keep on using it. Thanks!
