    David M. Thibodeau

    <!--Introduction--> Introduction Many factors come into play when balancing the pros and cons of a loudspeaker system that uses digital signal processing (DSP) vs. fully analog. This has made DSP use in loudspeaker system design a polarizing topic in recent years. In favor of the analog approach, traditional passive analog crossover networks in two-way systems are well understood, with no analog-to-digital conversion, minimal group delay, and near zero latency. Some manufacturers …
