Audison Prima APK 163

Audison Prima APK 163 - 3-Way 16.5 cm Front System with OEM-Optimized Crossovers

The Audison Prima APK 163 is a 3-way front system (6.5 inches/16.5 cm) that makes it easy to replace factory speakers – without running additional cables through the door. It combines the AP 1 tweeter, the AP 4 midrange, and the AP 6.5 woofer, each with its own passive crossover tailored to the speaker. High-current quick-connect terminals accelerate installation. Available at Carhifi.shop.

Technical Highlights

• AP 1 tweeter with 26 mm membrane diameter and wide-band surround for high efficiency and low resonant frequency.
• Acoustic lens on the AP 1 for correcting boosts/dips between 10–13 kHz behind restrictive OEM grilles.
• Dedicated passive crossovers for each component: APCX TW (with level control 0 dB/+2 dB), APCX MD, and APCX WF – compact and designed for OEM integration.
• AP 4 midrange with extended frequency response and high efficiency for clear vocal reproduction.
• AP 6.5 woofer with 32 mm pure copper voice coil for high power handling and controlled deep bass.
• Water-repellent treated, embossed paper cones (AP 6.5/AP 4), FEM-designed and optimized with Klippel R&D Scan Vibrometer.
• Reduced mounting depth for AP 6.5 and AP 4 for installation in near-series positions.
• TPU surround with flat TripleWave profile for linear excursion and low distortion.
• Compact, abrasion and scratch-resistant baskets; the motor is bonded with damping epoxy.
• AP 6.5 with high-current dual terminals and temperature-resistant cover against short circuits.
• Development and fine-tuning with the KLIPPEL suite.

Installation & Compatibility

The compact crossovers and reduced mounting depth of the drivers facilitate integration into OEM positions. Thanks to the dedicated crossovers, it is usually not necessary to run additional cables through the door. The level control on the APCX TW (+2 dB) helps you adapt the high frequencies to the vehicle acoustics. The acoustic lens of the AP 1 optimizes the radiation pattern behind standard grille covers.
