Audio-maker Harman Kardon has introduced two new home theater sound systems, the SB 30 and the BDS x70 family, in anticipation of next week's CES show. The SB 30 is a wireless subwoofer packaged with a soundbar speaker array. The BDS x70 series is a compact all-in-one component sound system available in several configurations with either 2.1-channel or 5.1-channel audio.
