The Harmon Kardon HKS-6 is a pair of 2-way surround channel speakers from Harman Kardon's HKTS Series. The speakers are meant to be used along with any 5.1 channel speaker system, such as Harman Kardon's HKTS-15, to upgrade the system to 7.1 channel surround. The speakers feature a 3" midrange driver, a 1/2" dome tweeter, and are capable of producing up to 80 watts of power. They are magnetically shielded allowing them to be placed near video monitors. The HKS-6 come with colour-coded speaker cables for easy installation of the speakers in the rear surround speaker positions as well as wall-mount brackets and leatherette coasters. Compared to Harman Kardon's HKS-9, the speakers have a smaller frequency range, lower power output and only a single midrange driver as opposed to the dual midrange drivers of the HKS-9. The speakers are also about 3" shorter than the HKS-9, at approximately 6.5" tall.
