Well, one of the Red and black switches on the back of the Sub that clamps the speaker wire down is broken on my Ifi. nothing happened i just noticed the sound seemed weird and i looked back there and it was loose and not locked down. i took it out and took the spring out and repositioned it and it looks like part of the plastic switch broke off. I really am dissapointed in this and need to know what to do. Will klipsch repair this for me? Can i replace the terminal easily? Any other solutions?
