Most speaker systems need crossovers. The amount of energy required to produce air vibrations for us to feel can cause distortion in speaker drivers. This problem can be solved by adding multiple drivers that each handle a different area of the frequency spectrum. A crossover is used to separate the signals so the speakers can work efficiently. In tactile sound there is no transmission in the air. Your brain combines what is felt and what is heard into a full frequency experience. In this case you become the crossover, the smartest crossover on the planet!!← Where is the crossover?
