1. Neodymium magnet optimized with FEA simulations for real dynamics and utmost control.

2. Very low carbon content CNC machined plates, for maximum magnetic permeability

and low distortion at high power levels.

3. Aluminium covered pole for a linear impedance modulation and low distortion.

4. 50 mm CCAW double layer voice coil wound on a Polyamide former for exceptional

power handling and compression-free re production even in the most demanding
musical passages.

5. Exponential V-cone® with optimized geometry for utmost linearity and dispersion.

6. “Boundary Free” IIR rubber surround, for better efficiency and wider mid-bass frequency.

7. Pressed-pulp cone with cotton fibres, combining stiffness and lightweight, to achieve

wide frequency response and limited break-ups at high frequency.

8. Three-spoke, very acoustically transparent anti-resonant aluminium alloy basket
featuring built-in venting holes.

9. CNC machined elegant diamond-cut basket edge featuring the Hertz logo.

10. Die-cast aluminium factory provided grille featuring diamond-cut aluminium Hertz logo.
