Harman Kardon offers its Harman Kardon HKTS 16 5.1-Channel Surround-Sound Speaker System in Black, model no. HKTS 16BQ, for $169.99 with free 2-day shipping. That's tied with our mention from two weeks ago as the lowest total price we've seen for a new system. (It's the best deal today by $80.) 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.
