AUDISON The APX 690 features an exclusive 40 mm horn loading dome tweeter that contributes to maximize efficiency up to 96dB SPL and an acoustics lens specifically designed and applied to the tweeter to increase dispersion in the high frequency range. To strengthen the emission of very high frequency ranges otherwise affected by off - axis positioning compared to the listening point, the APX 690 featuring a super tweeter.

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) super tweeter 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.
• Large motor assembly, optimised with FEM (Finite Element Method) technology, for stable control and linear excursion.
• Grille included.
