APK 165 ohm2 system features 2 crossovers dedicated to woofer and tweeter and separated, to ease the installation. APCX WF ohm2 crossover shapes AP 6.5 ohm2s frequency response to match it optimally with AP 1 tweeter; it also employs a Low ESR inductor, essential to maximize the power transfer to the 2 ohm coil. APCX TW ohm2 tweeter crossover, instead, is provided with the Hi-Contour function, to enhance the high frequencies, designed to achieve the correct timbre balance with rich low frequencies guaranteed by the woofer.
