Right now, my setup consists of a 2 channel receiver, a low quality speaker, and the Klipsch RW-12D subwoofer. The subwoofer is connected using the left and right speaker outputs on the receiver to the left and right inputs on the subwoofer using speaker wire I found from an older setup. I tested this setup a couple days ago and it worked, with the low quality speaker just testing the music portion to see if its going through.
Today, I turned it on, and the subwoofer was set to about +2 db on the digital menu, and the receiver was turning off saying 'protect' on the screen. So I moved the receiver away from the subwoofer, and I turned it up again and it seemed to stay on this time but one more dial turn on the receiver and the subwoofer suddenly got a lot quieter. My windows were still rattling, but the front woofer was not blowing air or moving as much as it was on the same volume level, as it was a minute before.
My question is, did i blow the subwoofer? Did the receiver go into some kind of safe mode and quiet the audio output? Is it possible to blow the subwoofer with my current setup?
