Audison Prima

Audison Prima was designed to meet the interest of the car model enthusiasts who like to appreciate all the nuances of the musical message with components that are perfectly integrated in the car OEM system, preserving the most precious Prima on Audison requirement of OEM integration: space.

• Concentric Coaxial Tweeter: tweeter is mounted within the woofer with one single point of emission providing consistent phase response, with an accurate recreation of the sound stage comparable to that of a component system.
• Tweeter features an acoustic lens specifically designed to ensure an extremely linear frequency response, even in off-axis placement, typical of in-door installations.
• 32 mm pure copper voice coil, for high power handling and outstanding low frequency control.
• Overall mounting depth optimized for OEM Integration thanks to the concentric tweeter and the low profile basket.
• Water-repellent treated paper cone, featuring a profile developed with FEM (Finite Element Method) simulation technology and optimized with the Klippel Scan Vibrometer.
• TPU (thermoplastic polyurethane) suspension with unique “triple wave” profile for maximum linearity of excursion.
• Compact basket, protected by abrasion-resistant and scratchproof coating, the motor affixed with damping epoxy adhesive.
• High current fast-on terminal with double contact on positive and negative poles for high flexibility and quick connection. The terminal features a temperature resistant plastic cover, protecting it against accidental short circuits.
• Developed with the KLIPPEL suite.

APX 4 features a concentric coaxial tweeter: with one single point of sound emission it is possible to obtain a consistent in-phase response, with consequent reconstruction of the acoustic scene comparable to a system of separate woofer + tweeter.The 4³ cones surround features the exclusive shallow Triple Wave profile, for maximum excursion linearity.
