• AP 1 tweeter with 26 mm diameter diaphragm combined with a wide-roll surround provides maximum efficiency and reduced resonance frequency.
• 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.
• Dedicated crossovers for each component: APCX TW compact tweeterpassive crossover optimized 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 optimized for OEM Integration.
• AP4 midbass with extended frequency response, combined with high efficiency.
• AP 6.5 woofer with 32 mm pure copper voice coil, for high power handling and outstanding low frequency control.
• 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.
• AP 6.5 woofer and AP 4 midbass with reduced mounting depth, providing ease of installation in OEM placements.
• Woofer AP 6.5 and midbass AP 4 with TPU (thermoplastic polyurethane) edge, featuring the unique shallow “TripleWave” profile for maximum linearity of excursion.
• 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.
• 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.
• Developed with the KLIPPEL suite.
