Investigation into 4th-order Bessel active crossovers produces interesting results. Implementing 4th-order Bessel crossovers required development of several new approaches. The classic Bessel equations do not work well for crossover use. Adapting Linkwitz-Riley theory shows the way to a better Bessel. Development of new Bessel-derived transfer functions eliminate several faults of the classic approach. The areas investigated include roll-off rates, summed magnitude responses, phase shifts, and group delays. Also investigated is direct state-variable implementation of 4th-order Bessel functions. A summary of comparison results with the Linkwitz-Riley case concludes the study.
