just picked one of these up and its working but has a hum noise when on with no input and gets louder with the gain up? pulled out the amp and resistors r101 r89 and r87 get hot fast and the board is brown where they attach. don't know if it has 2 problems or if that's why it hums. thanks for any help on this

I am trying to find more info on the old sw-15 subwoofer, not the 2 the one with the passive radiator. not much on the main klipsch page. thanks http://www.klipsch.com/products/sw-15
