Audison Prima APK 165 Ohm2 - 2-Way 16.5 cm Front System, 2 Ohm, 300 W
The Audison Prima APK 165 Ohm2 is a 2-way front system that operates at 2 ohms, thereby efficiently utilizing the available power of modern compact amplifiers. With 165mm woofers, 26mm tweeters, and passive crossovers, you get clean, controlled reproduction from 50 Hz to 20 kHz. The crossovers can be set to 4.5 or 5 kHz and offer an adjustable tweeter level, allowing you to fine-tune the sound directly in the vehicle.
Technical Highlights
- 2-ohm system for optimal power delivery to compatible amplifiers (e.g., AP8.9 bit)
- Tuned passive crossovers with selectable crossover frequency (4.5/5 kHz) and tweeter boost
- High efficiency and linear excursion for high-level reproduction
- OEM-friendly installation thanks to low mounting depth, fast-on terminals, and compact basket

Features & Construction
- 2-ohm design to effectively utilize the 65 W per channel at 2 ohms of the AP8.9 bit
- Woofer resonance frequency at 75 Hz for extended bass down to 50 Hz and more punch in the bass range
- 25mm voice coil on the woofer for high efficiency (up to 95 dB)
- 10mm winding height of the voice coil for 2.8 mm linear excursion and low distortion at higher levels
- APCX WF 2-ohm woofer crossover with low-loss coils for a clean transition to the tweeter
- APCX TW 2-ohm tweeter crossover with Hi-Contour for boosting high frequencies for balanced overall sound
- AP 1 tweeter with acoustic lens for smoothing 10â13 kHz â helpful for critical OEM positions behind factory grilles
- Integrated connection cables on the passive crossover with OEM-compliant fast-on connectors; different poles for safe, confusion-free connection
- AP 6.5 2-ohm woofer with water-repellent treated paper cone, FEM-developed and optimized with Klippel Scan Vibrometer
- Reduced mounting depth of the woofer facilitates use in factory locations
- TPU surround with "Triple Wave" profile for maximum linearity of excursion
- Compact, robustly coated basket; damping epoxy adhesive for stable motor connection
- High-current quick terminal with double contact on positive/negative for flexible, fast wiring; heat-resistant cover against short circuits
- Developed and verified with the KLIPPEL Suite
Installation & Compatibility
The system is designed for OEM locations and ideally harmonizes with amplifiers that deliver high power at 2 ohms, especially the Audison AP8.9 bit. Thanks to reduced mounting depth, fast-on terminals, and the included passive crossovers, integration is quick and clean. The tweeter adjustment (+2 dB/0 dB) facilitates fine-tuning to vehicle acoustics and mounting position.
