3 WAY SYSTEM

1. AP 1 tweeter with 26 mm diameter diaphragm combined with
   a wide-roll surround provides maximum efficiency and reduced
   resonance frequency.
2. AP 1 tweeter with acoustic lens designed to compensate for
   and fine tune the in-car frequency response anomalies in the
   10kHz – 13kHz bandwidth caused by restrictive OEM grilles in
   critical OEM placements.
3. Dedicated crossovers for each component: APCX TW compact tweeter
   passive crossover optimised for OEM Integration featuring an
   attenuation switch (0 dB, +2dB) to tune the in-car response according
   to different installation conditions; APCX MD midbass crossover
   and APCX WF woofer crossover. The passive crossovers boast very
   reduced dimensions and are optimised for OEM Integration.
4. AP4 midbass with extended frequency response, combined
   with high efficiency.
5. AP 6.5 woofer with 32 mm pure copper voice coil, for high power
   handling and outstanding low frequency control.
6. AP 6.5 woofer and AP 4 midbass with water-repellent treated
   paper cone, featuring a profile developed with FEM (Finite
   Element Method) simulation technology and optimized with the
   Klippel R&D Scan Vibrometer.
7. AP 6.5 woofer and AP 4 midbass with reduced mounting depth,
   providing ease of installation in OEM placements.
8. AP 6.5 woofer and AP 4 midbass with TPU (Thermoplastic
   Polyurethane) surround, featuring the exclusive shallow “Triple
   Wave” profile, for maximum excursion linearity.
9. AP 6.5 woofer and AP 4 midbass with compact basket, protected
   by abrasion-resistant and scratch-proof coating, the motor
   affixed with damping epoxy adhesive.
10. AP 6.5 woofer with high current fast-on terminal with double
    contact on positive and negative poles for high flexibility and
    quick connection. The terminal features temperature resistant
    plastic cover, protecting it against accidental short circuits.
11. Developed with the KLIPPEL suite.
