Question about KLH HTA-4906 System
While watching tv at normal volume, my KLH subwoofer started to make a loud buzzing humming sound. I checked connections and wires, all good. I disconnected and placed subwoofer on table and under light to get better view. I then plugged in power cord and turned it on and same noise occurs. Took speaker out of enclosure and connected it to normal stereo output and it sounds ok. Could this be a power transformer problem or blown speaker? I did'nt think a blown speaker would still sound normal or does it? KLH model HTA 4906 six speaker surround sound system, powered subwoofer
That sounds like a bad plate amp. You may be better off getting a new sub if that is the case -it will cost more to repair than to get a used one from Craigslist.

Check the back side of your equipment. You may have be picking up hum because wires (power, speaker, etc) are placed, or fell, on top of the receiver. If they are, try rearranging things to be as uncluttered as possible, and not on top, or against any A/V equipment.

Make sure you have the speaker connection right if you do then it is a ground problem try plugging it in a different outlet
