Magico writes: “Magico’s Elliptical Symmetry Crossover (ESXO) produces a filter with greatly accelerated rolloff slopes. It uses a very specific notch response to achieve an acutely steep rolloff rate outside the passband without the addition of an electric pole. It is a unique type of electrical/acoustical filter that, in our view, offers a significant performance advantage over typical crossover filter types in audio applications.
Although you won’t see the ESXO network itself when you receive your pair of Magico loudspeakers, you will hear the results: the most pure music reproduction you’ve ever heard.”
