Harman Kardon offers its Harman Kardon HKTS 20 5.1-Channel Speaker System in Black for $219.99 with free shipping. That's tied with our May mention, the best deal now by $380, and the lowest total price we've seen for a new system. It features four 120-watt 2-way satellite speakers, one 120-watt dual-driver center-channel speaker, one 200-watt down-firing subwoofer, and all the necessary cables and wall-mount hardware.
