Features
- Horn Loaded Tweeter: 40 mm horn loaded dome tweeter
contributing to its incredible efficiency of up to 96 dB 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) sphere with unique “triple wave” profile for maximum linearity of excursion.
- 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.
