Hi, I just got the ST 300 Sound Bar with the wireless surround speakers. I am replacing my old Acoustimass 6 III system. I would like to use the subwoofer from the Acoustimass 6 and have connected it to the sound bar via the Acoustimass 3.5MM jack on the back of the sound bar. I do not hear any bass out of the subwoofer, and the Soundtouch app will not allow me to switch "on" the subwoofer. Any thoughts?
