Digital Subwoofer Amplifier with Electromotive Feedback

This innovative dsPIC30F2020-based project showcases an interesting approach for reducing speaker distortion and increasing bass response. A dual-coil speaker driver is implemented in the design, but only one of the coils is connected to the power amplifier. The other coil is used for electromotive feedback.
