We feel this term more accurately describes the method incorporated in our IEM’s to achieve the desired sound signature. While it is common in the industry to see phrases like three driver with three way crossover, we prefer to think of crossovers as the passive (and sometimes active) electronic components that utilize Butterworth and Zobel networks to achieve low pass, high pass and band pass filters.

 

Due to the limited amount of “real estate”, it is usually difficult to fit true electronic crossover components (particularly inductors) into an IEM if using anything more sophisticated than a first or second order filter. We use a combination of passive crossover components, acoustic dampers, tube size and bore size to shape the frequency response. This type of tuning network allows the balanced armature drivers to do what they do best without the interference of too many power- and space-consuming components.
