After 16 months of use, my Fender Bassman 150 tossed its speaker last night on stage as confirmed by the local repair shop. While starting the next song, I noticed that the volume was lower. Then it sounded like static replaced any sens of music. Finished the night running through the PA. Today, my local shop guy pulled the speaker and bench tested it. He noticed that it was a Chinese-made Eminance and said that the US ones were better. Any experience with this? I'm still getting the replacement one for now. Any suggestions for something more robust or was this just a fluke?
