  If there is no sound coming from one of your Harman Kardon Subwoofer speakers, you can try the following: * Check the “Balance” control on your receiver/amplifier. * Ensure all wires and connections between the receiver/amplifier and speakers are properly connected. * Make sure that none of the speaker wires are frayed, cut, or punctured, and that no wires are touching each other. * In Dolby Digital or DTS mode, ensure that the receiver/processor is configured so that the speaker in question is enabled. * Turn off all electronics and switch the problematic speaker with a working one. If the problem stays in the same place, the issue is likely with your receiver or amplifier. If the problem follows the speaker, further assistance may be needed.
