1. Extraordinary large neodymium magnet, optimized with FEA simulations, to ensure
magnetic field stability even under high excursion.
2. Very low carbon content CNC machined plates, for maximum magnetic permeability and
low distortion at high power levels.
3. Voice coil internal magnet with high size / performance ratio, for maximum efficiency.
4. CCAW, 100 mm (4”) voice coil, capable of handling 1400 W musical power, keeping the working
temperature very low, reducing dynamic compression to the minimum.
5. Voice coil wound with In/Out method, for even cooling of the different coil layers.
6. Voice coil wound on TIL former: this material made from fibreglass combines the heat
dissipation properties of aluminium with the stiffness of Polyamide composites, for a
no-compromise acoustic performance.
7. Central pole featuring “Aluminium Shorting Ring”, for minimum distortion and maximum
extension at low frequency.
8. Boundary Free” IIR rubber surround, for higher SPL performance with same external diameter.
9. Exponential V-cone
®
with optimized geometry for high cone stiffness and strong
resistance to deformation even at maximum excursions.
10. Mineral-injected paper cone, for superior rigidity and damping.
11. Very acoustically transparent anti-resonant aluminium alloy basket featuring six-spoke
self-standing structure and built-in venting holes underneath the spider.
12. CNC machined elegant diamond-cut basket edge featuring the Hertz logo.
13. Ergonomic, ultra-compact design, with array of electro-acoustic parameters optimized
for sealed box application with 17 - 25 lt volume.
