22. he listener This phenomenon is called Doppler effect thanks to Mr Doppler who discovered it and can also be found in loudspeakers as the speaker diaphragm is displaced by low frequencies the treble frequencies seem to be raised in loudness or lowered when the diaphragm reverses its direction Quite similar in sound to a vibrato it is precisely this effect that we call intermodulation distortion As a consequence we cannot expect a single loudspeaker to reproduce signals with the same quality over the entire audio spectrum Therefore 2 3 or 4 way systems have become the standard today Speakers that need to reproduce only a limited range of the audio spectrum can accomplish this task with much greater accuracy i e they produce a more regular frequency response and dispersion pattern To operate a speaker system that consists of several loudspeakers for the various frequency ranges you have to provide a variety of input signals for the single speakers For this purpose crossover networks split up the input signal into several frequency bands You can use passive crossovers wired between amplifier and speaker or active systems placed before the amplifier in the signal chain Passive crossovers are usually employed in hi fi speaker boxes 1 2 SUPER X PRO the high end frequency crossover The BEHRINGER SUPER X PRO CX3400 is a high quality active crossover network that can be used for 2 3 or even 4 way sound reinforcement systems
