1. Tetolon Fiber dome optimized with FEA simulations, for excellent dynamics
and angle dispersion.
2. Double Neodymium magnet optimized with FEA simulations, for maximum
field symmetry and exceptional transfer efficiency.
3. Extended rear chamber filled with natural fibre non-woven sound-absorption
material, for better damping and more natural acoustic emission.
4. Massive 28 mm CCAW (Copper Clad Aluminium Wire) ferrofluid-cooled mobile
voice coil for outstanding power handling.
5. 900Hz FS to ensure a well damped high pass frequency roll-off, allowing low
cut-off frequency crossover point.
6. Faceplate featuring FEM (Finite Element Modeling) optimized geometry, for
high linearity in off-axis installations.
7. Wide array of installation accessories, for an easy OEM integration.
8. Separate ultra-compact crossover to the benefit of simplicity
and flexibility of installation featuring level adjustment switch (0, -2dB).
