I have used lots of products from Harman Kardon over the years as well as the firms sister company JBL. Harman Kardon makes all sorts of speakers ranging for computer speakers to home theater gear. Most of the stuff tends to be high-end, which means expensive.
Harman Kardon has unveiled a couple new surround sound home theater speaker systems. The new systems include the HKTS 20 and the HKTS 30. The speaker systems are almost identical with lots of the same features including a 200W powered 8-inch subwoofer.
