I got an Ashdown Electric Blue 180 (180watts 1-15" speaker) I love the sound, except when I turn it up over about 3 in any combination of master and pre volume it rattles like the speaker is blown. I plugged it into a new GK 2-10" cabs and it sounds great. So I changed out the 15" witha new Eminence Kappa Pro, (400 watt capacity) did the same thing, so it's got to be the cabinet itself. I tightened and screws that were visible but still doing the same thing. Anyone have any thoughts or been though this with an Ashdown combo? For now I'm using the combo like a head with my GK 2-10. That sux to lug the combo around like that.
