Fallen bookshelf speaker
My Polk Audio RTiA1 speaker fell off my Video Secure stand from 30", about ten second after placing it on it. The stand was defective. The speaker looks fine, but unfortunately no sound is coming out of it. I checked all of the banana plugs, and there all secure. Again it looks perfectly okay, and fell on it's side, so I have no idea whats wrong. Could there be an internal wire that may have been shook lose in the fall, or something else? Any ideas. The speakers were fairly new, and sounded great wt my subwoofer. Does anyone, have an idea what the problem could be? If the speaker is damaged, is it worth getting repaired?
