Crossover Design
When developing passive crossover networks for equalizing and filtering the separate channels of a multi-driver loudspeaker, a number of parameters have to be optimized at the same time. Apart from the crossover operation for a desired overall frequency response and the slew rate of the filters, the resulting directivity around the crossover frequency and the respective requirements have to be taken into consideration. Furthermore, the topology of high-power networks for large scale sound systems has to be optimized regarding power dissipation to keep the network devices from heating up. For designing passive networks we use commercial network solvers and optimizers as well as our own software tools, which take into account the influence of the network on the directivity. Especially for designing multi-way systems with overlapping frequency bands, like column speakers, a complete simulation of the system including all crossover functions is an indispensable tool for optimizing the radiation pattern.
