ABSTRACT:
A high-fidelity stereophonic automobile audio system has a rear speaker for each channel with a coaxial dual voice coil structure. One voice coil is optimized for full-range reproduction and is driven directly from a rear channel output of the vehicle radio. The other voice coil is optimized for sub-woofer operation and is driven through a separate sub-woofer amplifier connected to both the front and rear radio outputs of the respective channels. The system provides improved bass response in all positions of the radio fader control without the need for separate sub-woofer drivers, and other provisions. The dual voice coils may be wound on a seamless coil former for improved speaker performance.
