Prima APK 163 by Audison
Audison Prima APK 163 is a 6.5 inch (16.5 cm) Speaker Set as a three-way system with AP 1 Tweeter, AP 4 Midbass, and AP 6.5 Woofer. Custom, compact passive Crossovers (APCX TW with damping switch 0 dB/+2 dB, APCX MD, APCX WF) are optimized for OEM integration. The AP 1 Tweeter uses an acoustic lens and a 26 mm diaphragm with a wideband surround; the AP 6.5 Woofer features a 32 mm voice coil made of pure copper. Materials include High Density Flux Ferrite in the Woofer, water-repellent treated paper in the Woofer and Midbass, and TELOTON-FIBER in the Tweeter. AP 6.5 and AP 4 have reduced installation depth, TPU edge with flat TripleWave profile, and a compact basket with abrasion and scratch-resistant coating, with the motor secured using damping epoxy glue. The high-current quick-connect terminal on the AP 6.5 with double contact and temperature-resistant cover is integrated. Developed with the KLIPPEL suite; the AP 4 is designed for extended frequency response and high efficiency. Technical specifications: Continuous power 125 W, peak 375 W, sensitivity 93.5 dB, impedance 4 Ohm, frequency response 50–20k, SPL Woofer 89.5 dB. Crossover tuning: Low pass 600 Hz at 6 dB/oct., High pass 3.5 kHz at 6 dB/oct.; Weights: Woofer 0.78 kg, Tweeter 0.04 kg.
