APK 165 Ohm2 Kit | 300 W Peak Power | Kit 2 way 2 ohm | AP 1 + AP 6.5 Ω2 + Crossover

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.

  • 2 Ω impedance, to fully exploit the 65 W power per channel at 2 Ω of the AP8.9-bit amplifier.
  • 75 Hz resonance frequency, to extend the frequency range down to low frequencies up to 50 Hz and increase the SPL in the low range.
  • 25 mm mobile voice coil to maximize efficiency achieving 95 dB.
  • 10 mm winding height mobile voice coil to increase maximum linear excursion up to 2,8 mm and minimize distortion, even at high listening levels.
  • APCX WF 2Ω dedicated woofer crossover with low-loss voice coils to shape the frequency response for an optimal match with the tweeter.
  • APCX TW 2Ω tweeter crossover featuring the Hi-Contour function to enhance high frequencies, designed to achieve the correct timbre balance with rich low frequencies guaranteed by the woofer.
  • AP 1 tweeter with an acoustic lens designed to balance the frequency response in the 10kHz 13kHz range, to optimize the product’s acoustic emission in critical OEM placements, where the product performance is affected by the presence of the factory grille.
  • Connection cable integrated into the passive crossover and terminated with fast-on connectors conforming to OEM integration. The terminations, which are different at each of the two poles, eliminate any possible connection errors, speeding up the installation process and making it safe over time.
  • AP 6.5 2Ω woofer featuring water-repellent treated paper cone, with profile developed with FEM simulation technology and optimized with Klippel Scan Vibrometer.
  • Woofer with reduced mounting depth, providing ease of installation in OEM placements.
  • Woofer with TPU (thermoplastic polyurethane) edge, featuring the unique “triple wave” profile for maximum linearity of excursion.
  • Woofer with compact basket, protected by abrasion-resistant and scratch-proof coating. Damping epoxy glue provides perfect coupling with the motor system.
  • Woofer with a high current fast-on terminal with double contact on positive and negative poles for high flexibility and quick connection. The terminal features a temperature-resistant plastic cover, protecting it against accidental short circuits.
  • Developed with the KLIPPEL suite.
