APX 690 | COAXIAL

1 Horn Loaded Tweeter: 40 mm horn loaded dome tweeter
contributing to its incredible efficiency of up to 96dB SPL.
2 Acoustics lens applied to the tweeter, specifically designed to
increase dispersion in the high frequency range.
3 PEI (Polyethylene injected) supertweeter 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) surround, featuring the exclusive
shallow “Triple Wave” profile, for maximum excursion linearity.
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.
