1. Symmetrical dual Neodymium magnet structure specifically developed with
FEM (Finite Element Modeling) 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 fibers, combining
stiffness and lightweight for a wide frequency response. Cone profile
geometrically optimized 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.
7. Full protection metal mesh grill featuring the aluminium Hertz logo and
attractive look mineral powder coated inner grill are included for several
install combinations.
