APX 6.5 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 cones surround features the exclusive shallow Triple Wave profile, for maximum excursion linearity.

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. 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) suspension with unique “triple wave” profile for maximum linearity of excursion.
7. Compact basket, protected by abrasion-resistant and scratch-proof
   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. –
