The resonance frequency of 145 Hz, a very low value for a 50 mm (2 in.) loudspeaker, was obtained thanks to the use of a 25 mm (1 in.) voice coil, ensuring a controlled extension at low frequencies for an optimal crossover point with the woofer.
The aluminium cone, in combination with the copper shorting ring that flattens the impedance, allows for the response to be extended up to 20 kHz. The special magnetic group made with double symmetrical Neodymium magnet also contributes to achieve this exceptional extension at high frequencies while maintaining very compact dimensions.
This electroacoustic configuration has led to obtain a particularly wide frequency response, which extends from 150 Hz up to 20 kHz, giving the AP 2 the well-deserved name of wide range.
