Audison Prima AP 4 Midrange Speaker

High-Efficiency 100mm Midbass Driver with Extended Frequency Response and OEM Integration
The Audison Prima AP 4 is a high-performance midrange speaker engineered for audiophiles seeking balanced sound, high efficiency, and compact design. With a 120W peak power rating and a 100mm diameter, it is ideal for car audio systems requiring tight integration into factory speaker locations. A 25mm pure copper voice coil ensures precise tonal balance in the mid to high frequency range, while the water-repellent treated paper cone, enhanced by FEM simulation and Klippel R&D scan vibrometry, provides superior mechanical performance without requiring a passive crossover.

The AP 4’s Triple Wave TPU surround supports linear excursion and durability, and its compact basket is coated for protection against abrasion and scratches. Designed to simplify OEM installations, it ensures easy mounting even in shallow factory spaces. Developed using the KLIPPEL suite, this speaker offers reliable, high-quality audio performance in real-world driving conditions.
