Audison APK 690 Kit | 300 W Peak Power | Kit 2 way 4 ohm | AP 1 + AP 690 + Crossover

AP 1 Tweeter

1. 26 mm diameter diaphragm combined with a wide-roll surround provides maximum efficiency and reduced resonance frequency.
2. Acoustic lens designed to compensate for the in-car frequency response in the 10kHz 13kHz bandwidth caused by critical OEM placements.

AP 690 Woofer

1. 25 mm pure copper voice coil, for high power handling and outstanding low frequency control.
2. 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.
3. Reduced mounting depth, providing ease of installation in OEM placements.
4. “Triple wave” surround profile for maximum linearity of excursion.
5. Compact basket, protected by abrasion-resistant and scratchproof coating, the motor affixed with damping epoxy adhesive.
6. High current fast-on terminal with double contact on positive and negative poles for high flexibility and quick connection.

APCX TW 690 Crossover

1. Optimized for OEM Integration featuring an attenuation switch(0 dB, +3dB) to tune the in-car response according to different installation conditions.
