APX4APX4 100 mm Coaxial Speakers

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.

Highlights

  • 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 a single point of sound emission, it delivers a consistent in-phase response, enabling accurate reconstruction of the acoustic scene, comparable to a system with a separate woofer and tweeter. The 4″ cone surround features the exclusive shallow Triple Wave profile, ensuring maximum excursion linearity.
