• said first frequency range being lower than said second frequency range;
• means for supplying audio signals to said first and second transducer means;
• and
• means for changing the relative phase of driving signals from said driving means when the out-of-phase response would have been approximately the same as the in-phase response;
• said structural member sized to be positioned on a wearer's torso adjacent the head and shaped to conform to the wearer's torso;
• wherein said structural member is positioned on the wearer's torso, said first transducer means is positioned adjacent one of the wearer's ears and said second transducer means is positioned adjacent the other of the wearer's ears;
• whereby the response of said system in said first frequency range is enhanced.
