1.PURE COPPER VOICE COIL: wound on a Polyamide former for high power handling combined with very low intermodulation distortion of vocals.
2.EXPONENTIAL V-CONE® PROFILE: geometrically optimized for utmost linearity and dispersion in the mid frequency range. (Logo VCone)
3.“BOUNDARY FREE” RUBBER SURROUND: for improved efficiency and wider mid-bass frequency. (Logo Boundary Free)
4.HIGH DENSITY FLUX FERRITE MAGNET: combined with very low carbon content iron plates, for low distortion at high power levels.
5.BASKET: low mounting depth, acoustically transparent aluminium alloy basket with elegant diamond cutting and featuring the aluminium Hertz logo.
The exponential profile gets very close to the perfect one, providing exceptional dispersion.
This technology provides the ability to achieve wider emission surface of the cone compared to speakers with same diameter; that way, the cone manages to move a bigger mass of air, so it produces more acoustic pressure.
This special surround is built from highly pure IIR butyl rubber, ensuring extraordinary thermal and mechanical linearity.
