APX 4

4″ COAXIAL

1. 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.
2. The tweeter features an acoustic lens specifically designed to
   ensure an extremely linear frequency response, even in off-axis
   placement, typical of in-door installations.
3. 32 mm pure copper voice coil, for high power handling and
   outstanding low-frequency control
4. Overall mounting depth optimized for OEM Integration thanks
   to the concentric tweeter and the low profile basket
5. Water-repellent treated paper cone, featuring a profile developed
   with FEM (Finite Element Method) simulation technology and
   optimized with the Klippel Scan Vibrometer.
6. TPU (Thermoplastic Polyurethane) surround, featuring the
   exclusive shallow “Triple Wave” profile, for maximum excursion
   linearity.
7. Compact basket, protected by abrasion-resistant and scratchproof coating, the motor affixed with damping epoxy adhesive.
8. 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.
9. Developed with the KLIPPEL suite.
