The pressure that pushes the air inside the reflex duct is extremely high. Consider the analogy of hydraulic lines that push water upward. As the salt loses fluid pressure, the jets lose speed and weaken. Hence the goal must be to retain the optimal pressure within the reflex duct to ensure a consistent strength in the acoustic wave, while avoiding the audible noise past pressure speeds of 130km/h. The tweeter with a soft dome of 38 mm in diameter, without coolant iron in the air gap, and a “waveguide” support, make it at the same time precise but soft, natural but resolute. Above all, it is so chaste that it can withstand high sound pressures and very low crossover frequencies of the crossover filter, for the benefit of a higher tonal cohesion between the two transducers.
