I have a polk surroundbar 6000 and all of the reviews send the same 2 messages. It sounds good for the price and the wireless subwoofer range is terrible. I agree with both. The Subwoofer cannot be seen where I have it so if I could attach a wire and run it up the side of the subwoofer to act as an antenna that would be great. Any thoughts or alternatives will be appreciated.
Then open it up, find the internal antenna and splice a larger antenna on. A larger antenna for reception will help, although a larger transmitting antenna on the other end would help more. Do not surround either with large metal objects that will attenuate the already poor signal.
