APX 570 Coaxial | 210 W Peak Power | 5″ x 7″ | 4 ohm

APX 570 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 5x7" cones surround features an exclusive shallow Triple Wave profile, for maximum excursion linearity.

Features

  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) sphere 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.
