This paper describes the design and implementation of a low cost portable speaker system with digital signal
processing (DSP) enhanced performance. The cost of incorporating DSP into a low cost consumer audio product is
typically prohibitive. Latest transducer developments in conjunction with recent advances in low cost audio digital
signal processors have made it possible to consider a commercial board level implementation of a small portable
speaker system with significant audio quality enhancement.
