The two-way system features an AP 1 tweeter and AP 6.5 woofer. APCX TW crossover features a two-position level selector providing the ability to adapt its response to its two main applications: +2dB if installed behind the OEM grille, and 0dB for an A-pillar installation without additional grilles between the tweeter and the listener. To ease the installation in OEM placements the woofers are equipped with high current fast-on terminals with double contact on positive and negative poles for high flexibility and quick connection.

• 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 an 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.
• APCX TW very compact tweeter passive crossover optimized for OEM Integration featuring an attenuation switch (0 dB, +2dB) to tune the in-car response according to different installation conditions.
• Passive crossovers are supplied with fast-on connectors that conform to OEM integration. The ends, different in each of the two poles, eliminate any possible connection errors and speed up the
  required installation time.
• AP 6.5 woofer with 32 mm pure copper voice coil, for high power handling and outstanding low-frequency control.
• AP 6.5 woofer with a water-repellent treated paper cone, featuring a profile developed with FEM (Finite Element Method) simulation technology and optimized with the Klippel Scan Vibrometer.
• AP 6.5 woofer with reduced mounting depth, providing ease of installation in OEM placements.
• AP 6.5 woofer with TPU (thermoplastic polyurethane) edge, featuring the unique “triple wave” profile for maximum linearity of excursion.
• AP 6.5 woofer with compact basket, protected by abrasion-resistant and scratch-proof coating, the motor affixed with damping epoxy adhesive. 
• AP 6.5 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.
