Hi, I am asking for advice because I let my brother's band borrow my Steelsound 2X10 and my Hartke Model 2000 Bass head for band practice and I get it back and the right speaker rattles when I play low notes. I press my hand against the right speaker and it doesnt sound as bad, the left speaker does not rattle at all., the high notes sound fine. Maybe the cab was just a piece of junk in the first place, I don't know but its never sounded like this and I've played a few gigs with it and its never sounded like this. I got it back and the master volume was on 9 but the pre-amp blend was at 3, maybe this caused it, I'm not sure. It still plays but it sounds sort of muddy and rattles. It almost sounds like there is something in it rattling. I'm not sure what the cause of this could be. I don't know much about speakers and whatnot. Any advice would be appreciated. thanks.
