Audison APX 690 Coaxial | 300 W Peak Power | 6″ x 9″ | 4 ohm

1. Horn Loaded Tweeter: 40 mm horn loaded dome tweeter
   contributing to its incredible efficiency of up to 96 dB SPL.
2. Acoustics lens applied to the tweeter, specifically designed to
   increase dispersion in the high frequency range.
3. PEI (Polyethylene injected) super tweeter employed to strengthen
   emission of very high frequency ranges otherwise affected by
   off-axis positioning common to rear deck installations.
4. Water-repellent treated paper cone, featuring a profile developed
   with FEM (Finite Element Method) simulation technology and
   optimized with the Klippel Scan Vibrometer.
5. Pure copper mobile voice coil, wound on Kapton former, for
   better thermal and mechanical capacity.
6. TPU (thermoplastic polyurethane) sphere with unique “triple wave” profile for maximum linearity of excursion.
7. Polycotton spider material ensuring reliable performance and
   linear response to musical transients.
8. Large motor assembly, optimised with FEM (Finite Element Method)
   technology, for stable control and linear excursion.
9. Low carbon content plates for maximum magnetic permeability
   and high heat dissipation.
10. Compact basket, protected by abrasion-resistant and scratch-proof
    coating, the motor affixed with damping epoxy adhesive.
11. High current fast-on terminal with temperature resistant plastic
    cover, protecting it against accidental short circuits.
12. Developed with the KLIPPEL suite.
