The crossover is the brain of every system. It is designed, developed and directly built to suit  the components it must fit. It results from simulation software and listening tests; it is improved through measurement instruments and assembled with professional care. Needless to say that coils, capacitors and resistors were selected among the first-grade audio components; needless to mention that their location onto the circuit board follows the ideal lines of the audio path; needless to remember that you don’t have to listen to the filter when you listen to music.
