The Harman Kardon HKTS-15 is a 5.1 channel home theater speaker system comprised of 4 satellite speakers, 1 center channel speaker and 1 subwoofer. The included satellite speakers all feature 3" midrange drivers, 1/2" high-frequency drivers, and produce up to 80 watts of power. The voice-matched dual-midrange center channel speaker has a 3/4" dome tweeter and also produces up to 80 watts of power. The 10" subwoofer that comes with the system features a built-in 100 watt amplifier for strong bass. All drivers and tweeters on the HKTS-15 speakers are magnetically shielded allowing them to be placed near video monitors. The system comes with wall-mount brackets for the satellite and center channel speakers, colour-coded speaker cables for easy installation, and a 1 year warranty. The HKTS-15 is a lower model than Harman Kardon's HKTS-18 since it has less powerful satellite and center channel speakers, a less powerful subwoofer, and lacks some of the additional features of the HKTS-18 such as the line-level sub/LFE input and multicolor LED indicator.
