Abstract
Apparatus for providing cross coupling of information on two channels in a two channel transducer. The apparatus preferably comprises a first housing having a first transducer adapted to convert an electrical signal on a first of the channels to sound, a second housing having a second transducer adapted to convert an electrical signal on a second of the channels to sound, the first transducer comprising a first voice coil and the first housing having a further first voice coil, the second transducer comprising a second voice coil and said second housing further having a further second voice coil, the first voice coil being electrically coupled to the further second voice coil and the second voice coil being electrically coupled to the further first voice coil. In the embodiments, the sound pressure signals from the further first voice coil is less than that from the first voice coil and is effectively acoustically substracted therefrom, and the sound pressure signal from the further second voice coil is less than that from the second voice coil and is effectively acoustically substracted therefrom, resulting in the desired cross coupling.
