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 4Â³ cones surround features the exclusive shallow Triple Wave profile, for maximum excursion linearity.

FEATURES

• 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. –
