1. Concentric coaxial tweeter built in the woofer voice coil, achieving one single

point of emission, to re-create the virtual sound-stage like in live music
performances.

2. 20 mm voice coil Tetolon fiber soft dome tweeter, featuring “Center Tuning

Duct” geometry, for lower resonance frequency and reduced harmonic
distortion.

3. Tweeter support working as a rear chamber, sized for low Fs, to ensure a well

damped high pass frequency roll-off, allowing low cut-off frequency
crossover point.

4. 36 mm pure copper woofer voice coil wound on a Polyamide former, for

outstanding power handling and dynamic compression-free reproduction.

5. Pressed-pulp cone with cotton fibers, combining stiffness and lightweight

for a wide frequency response. Cone profile geometrically refined to
perfec tly match with the t weeter emission ensuring phase consistency in
the crossover area.

6. “Boundary Free” rubber surround, for improved efficiency and wider

mid-bass frequency.

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

plates, for low distor tion at high power levels.

8. Low mounting depth, acoustically transparent aluminium alloy basket with

elegant diamond cutting and featuring the aluminium Hertz logo.

9. Anti-vibration rubber magnet cover, to damp spurious vibrations.
