Hey everyone, so I ended up trading in my hartke 115 and got a used gk 410, I believe its an SB. Anyway, I got it home and I plug into it and I start pushing it pretty hard to see what she'll take and what shes gonna sound like in a jam setting. Not so hard that I'm gonna kill it though, I'm not that stupid. Anyway, I kick up the woofer high at first and set the gain really low, almost off with my boost at about half way. Well guess what, im getting some kind of static/distortion and it almost sounds like a cone(s) is/are damaged. Now I'm not using a GK speakon cable yet, they didn't have one, so I'm going in with a quarter inch. The cab is used and I'm thinking they didn't check this thing out before they put it on the sales floor. I'd be happy with it, very happy, if it weren't for the static/distorted sounds. Does this sound like something any of you have had problems with these cabs before, is it something I'm doing wrong? Btw, the static isn't there ALL the time, only when its pushing some deep bass and or a deep note. In other words, it doesn't sound right to me but I don't know if IM doing something wrong or if its the cab. I've got the horn knob on the back set to normal and the little red switch turned to full range too.
