As in many other cases when it comes to high fidelity, there is the party of supporters and that of detractors. The latter, in particular, complain about the insertion of an additional circuit that the signal must pass through to reach the speakers, with its influences on sound and its negative effects on detail, background noise and so on. I do not feel like countering these fears, which are far from unfounded. In favor of electronic crossover, however, we can propose equally valid arguments."
But there is another aspect, which has a lot to do with the dynamic behavior of the speaker. When the loudspeaker is driven by a source with impedance comparable to its own, its impulsive response tends to lengthen and become oscillatory, with a considerable detriment to the transient behavior. If instead we drive a speaker with the direct output of an amplifier, the impulsive response of the loudspeaker improves considerably. This translates into greater control and better listening detail. This is why, in our opinion, the use of the electronic crossover in multiamplification can bring benefits to listening.
