Audison – APX 690

Audison APX 690

Features

• Horn Loaded Tweeter: 40 mm horn loaded dome tweeter contributing to its incredible efficiency of up to 96dB SPL.
• Acoustics lens applied to the tweeter, specifically designed to increase dispersion in the high frequency range.
• PEI (Polyethylene injected) supertweeter employed to strengthen emission of very high frequency ranges otherwise affected by off-axis positioning common to rear deck installations.
• Water-repellent treated paper cone, featuring a profile developed with FEM (Finite Element Method) simulation technology and optimized with the Klippel Scan Vibrometer.
• Pure copper mobile voice coil, wound on Kapton former, for better thermal and mechanical capacity.
• TPU (Thermoplastic Polyurethane) surround, featuring the exclusive shallow “Triple Wave” profile, for maximum excursion linearity.
• Polycotton spider material ensuring reliable performance and linear response to musical transients.
• Large motor assembly, optimised with FEM (Finite Element Method) technology, for stable control and linear excursion.
• Low carbon content plates for maximum magnetic permeability and high heat dissipation.
• Compact basket, protected by abrasion-resistant and scratch- proof 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.
