ABSTRACT:
A speaker interconnection block with two voice coils to be driven with separate amplifiers, or to use one amplifier to drive the two voice coils in series or parallel without having to reinterconnect the voice coils. This is achieved by locating the negative voice coil terminals next to each other and the positive voice terminals next to each other on the connection block. When two amplifiers are used to drive the voice coils, the sequence of connections of the amplifiers matches those of the voice coils mentioned above. When only one amplifier is used, that amplifier is connected between the two amplifier terminals farthest from each other. To connect the voice coils in series a single jumper is used to interconnect the two terminals in the center, and for parallel connection two jumpers are used to connect to two terminals at the ends of the sequence together separately.
