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 temperature resistant plastic cover, protecting it against accidental short circuits.
- Developed with the KLIPPEL suite.
