OK i have a SWR 18 that i got a few years ago. A while ago it just stoped working i was not playing on it when it happened so i dont think its a power from amp problem i also was only playing a small gk threw it so i doupt it could blow it. The speaker it self is not stiff, I can push on it and it goes in with ease. I was told to hook a 9v battery and look for speaker movment but i got nothing. It does nothing at all. I bypassed the cabnet and pluged it into my house sterio just to see if i could get some sound from raw speaker but i get no sound at all. Any ideas would be great.
