FEATURES

• The AP 1 tweeter with a 26 mm diaphragm diameter combined with a wide surround ensures maximum efficiency and reduced resonance frequency.
• AP 1 tweeter with acoustic lens, designed to compensate and finely tune anomalies in the vehicle’s frequency response in the 10kHz to 13kHz range caused by restrictive OEM grilles at critical OEM positions.
• Dedicated crossovers for each component: APCX TW compact tweeter passive crossover optimized for OEM integration and featuring a damping switch (0 dB, +2 dB) to adapt the vehicle response to different installation conditions; APCX MD midrange crossover and APCX WF woofer crossover. The passive crossovers are very compact and optimized for OEM integration.
• AP4 midrange driver with extended frequency response combined with high efficiency.
• AP 6.5 woofer with 32 mm pure copper voice coil for high power handling and excellent control of low frequencies.
• AP 6.5 woofer and AP 4 mid-woofer with water-repellent treated paper cone, whose profile was developed using FEM (Finite Element Method) simulation technology and optimized with the Klippel R&D Scan Vibrometer.
• AP 6.5 woofer and AP 4 mid-woofer with reduced mounting depth, allowing easy installation in OEM mounting locations.
• Woofer AP 6.5 and mid-woofer AP 4 with TPU surround (thermoplastic polyurethane), featuring the unique flat "TripleWave" profile for maximum linearity of excursion.
• AP 6.5 woofer and AP 4 mid-woofer with compact basket, protected by an abrasion-resistant and scratch-resistant coating; the motor is fixed with damping epoxy glue.
• AP 6.5 woofer with high-current quick-connect terminal with double contact on positive and negative poles for high flexibility and fast connection. The terminal has a heat-resistant plastic cover that protects it from accidental short circuits.
• Developed with the KLIPPEL suite.
