Harman Kardon offers its Harman Kardon HKTS 20 5.1-Channel Surround Sound Speaker System in Black for $199.99 with free shipping. That's $400 off list and tied with our mention from March as the lowest price we've seen for a new system. It features a 45Hz to 20kHz system frequency response, four 120-watt 2-way satellite speakers, 120-watt dual-driver center-channel speaker, 200-watt down-firing subwoofer, and all the necessary cables and wall-mount hardware.
