Description
APX 4
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 4″ cones surround features the exclusive shallow “Triple Wave” profile, for maximum excursion linearity.

- 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) surround, featuring the exclusive shallow “Triple Wave” profile, for maximum excursion linearity.
- Compact basket, protected by abrasion-resistant and scratch- proof 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.
