1. 38 mm pure copper woofer voice coil wound on a Polyamide former for

exceptional power handling and dynamic compression-free reproduction.

2. Pressed-pulp cone with cotton fibers material, combining stiffness and

lightweight for a wide frequency response.

3. Large rubber surround designed for long throw and optimal sound damping.

4. Over-sized ferrite magnet combined with very low carbon content iron

plates, for low distor tion at high power levels.

5. Aerodynamic thus acoustically transparent aluminium alloy basket,

eliminates rear wave reflections.

6. Anti-vibration rubber magnet cover, damps spurious vibrations.

7. 28mm voice coil Neodymium Tetolon fiber dome tweeter, for undistorted

mid-frequency reproduction.

8. 20mm voice coil Neodymium Tetolon fiber dome super tweeter, to naturally

compensate for drop-off in frequency response due to speaker horizontal
installation.

9. Tweeter faceplate with geometry optimized with FEM (Finite Element

Modeling) simulations, to provide excellent of f-axis frequency response up
to 24kHz by per fectly mixing the two tweeters’ emission.

10. Full protec tion metal mesh grill featuring the aluminium Hertz logo and

at tractive look mineral powder coated inner grill are included for several
install combinations.
