1. Symmetrical dual Neodymium magnet structure specifically developed with FEM (Finite Element Modelling) simulations, for superior dynamics and control.
2. 20 mm CCAW double layer voice coil wound on a Polyamide former with 8 decompression holes, for exceptional power handling and compression-free reproduction.
3. Exponential V-cone? profile pressed-pulp cone with cotton fibres, combining stiffness and lightweight for a wide frequency response. Cone profile geometrically optimised for utmost linearity and dispersion in the mid-high frequency range.
4. Boundary Free rubber surround, for better efficiency and wider mid-bass frequency.
5. Anti-vibration rubber magnet cover, to damp spurious vibrations, removable to fit limited mounting depth installations. 6. Acoustically transparent aluminium alloy basket with elegant diamond cutting and featuring the aluminium Hertz logo.
