Harman Kardon offers its Harman Kardon HKTS 16 5.1-Channel Surround-Sound Speaker System for $169.95 with free shipping. That's tied with our mention from three weeks ago, $430 off, and the lowest price we've seen for a new unit. It features a 45Hz to 20kHz frequency response, four 2-way, voice-matched satellite speakers, center-channel speaker, 200-watt RMS 8" powered subwoofer, and speaker cables.
