1 star for 5.1 speakers and good home theater quality sound and clarity from those speakers which are driven by a Sony 200 watt rms AV Receiver. But nothing to write home about.

Minus 4 stars for Harmon Kardon Sub 210 for failing after just only 18 months and poor customer support!! Just stopped working for no reason after 6 months of no usage! No power was going to the active sub. Harmon Kardon support could care less about me since they only had a one year warranty and we're willing only to pay for parts! Ha! Labor is everything and I will not be buying Harmon Kardon products ever again. I bought a $200 BA Subwoofer that is on its way instead of paying $69 for a diagnostic test at a contracted HK Service Center! What a crock of s*** Harmon Kardon fails on quality especially since the sub is the most crucial component of a home theater system! Pass on Harmon Kardon and their pathetic customer support.
