Audison Prima AP 4 User Manual

AP 4 MIDBASS

1 Very extended frequency response, in both high and low
frequencies, combined with high efciency.
2 No passive crossover required to maximize efciency: the
cone is optimised with the Klippel R&D Scan Vibrometer to
obtain a calibrated mechanical low-pass cut-off frequency.
3 Water-repellent treated paper cone, featuring a prole developed
with FEM (Finite Element Method) simulation technology and
optimized with the Klippel R&D Scan Vibrometer.
4 Reduced mounting depth, providing ease of installation in OEM
placements.
5 TPU (Thermoplastic Polyurethane) surround, featuring the exclusive
shallow “Triple Wave” prole, for maximum excursion linearity.
6 25 mm pure copper voice coil; ensuring precise balance in the
mid-high frequency range.
7 Compact basket, protected by abrasion-resistant and scratch-proof
coating.
8 Developed with the KLIPPEL suite.
