I recently experienced a woofer meltdown in one of my tower speakers. This set up was a passively biamped one--that is I had my receiver powering the mids and tweeter, and a subwoofer amp powering the woofer. One day I smelled burning plastic, and then discovered my amp was sizzling hot and the woofer was destroyed. So now I'm getting a new woofer, and I'm quite hesistant to re-connect the amp to the woofer because I don't know if it is what caused the woofer damage, or if it was a bad woofer to begin with. Does anyone know of a safe way to test to see if the amp is okay to use?
