ok, so first mistake was letting anyone else use my rig. I went a solid year or so without sharing my amp with anyone, and then the first other person I let use it kills it. Moral of the story - my gear will never act as backline again. BUT, the deal is my Bag End S15-D cabinet is now a mute. I was hoping that the speaker outputs on my Carvin R600 were the culprit but I checked them with a few other speakers and the outputs are fine. So I popped off the grate on my S15-D to check the speaker, and when I put any pressure on it I hear a scratching sound and sometimes a high pitch whistle. This means the speaker is f'd correct? If in fact the speaker is screwed, anyone know where I can order a new Bag End E-15 speaker. I don't know how long I can handle not having the rumble that this cabinet gives me.
