ABSTRACT:
An electroacoustical transducer includes a bobbin, a first acoustic radiator coupled to the bobbin through a first surround having a mechanical compliance, a second acoustic radiator generally rigidly coupled to the bobbin, and a basket. The first acoustic radiator is coupled to the basket through a second surround, and the second acoustic radiator is coupled to the basket through a third surround. The first surround is constructed to cause the first acoustic radiator to move out of phase with the second acoustic radiator relative to the bobbin when actuated by the bobbin at acoustic frequencies at and above a resonant frequency of the first acoustic radiator.
