Hello everyone, I have a great cab by GK that I really like, the NEO 112-II. I've used it on a lot of gigs for the last 5 years or so, but I'm having my first problem with it just now. I noticed a buzzing noise coming from the cab this past month. After investigation (trying a different cab with the same amp - my GK MB500-, trying another bass, trying another speakon cable), I was able to determine the problem really came from the cab and nothing else. Also, while listening closely to it, it felt like this was a mechanical/physical issue. It seems like something is moving in the cab, like there is something loose. Also, the buzzing is a major issue when the cab is in vertical standing, but not when it is horizontal. And even when in the vertical position, the problem is there only when the bass trap is at the bottom and the tweeter on top. If I put the cab upside down, no more buzzing (or almost none, instead of a LOT of buzzing on the other side). It really feels to me like there is something loose in the tweeter of my cab and that's what causing all the noise. And the thing is, I don't even use the tweeter of this cab. It is constantly turned off. So I was wondering if it was a good idea for me to just remove the tweeter from the cab since it seems to be what's causing my buzzing problem. Also, I want to make sure that I can remove the Tweeter without affecting the circuit of the cab and breaking everything. Does anyone happen to have an idea on how to effectively remove the tweeter from this cab? Or would it just be worse because it might create other buzzing problems? If anyone has any thought on this, I would really appreciate your help!
