Features
Boundary Free Surround
This technology provides the ability to achieve wider emission surface of the cone compared to speakers with the 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.

Additional Features
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.
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.
36mm Pure Copper Woofer Voice Coil
Wound on a Polyamide former, for outstanding power handling and dynamic compression-free reproduction.
Pressed-pulp Cone With Cotton Fibers
Combining stiffness and lightweight for a wide frequency response. Cone profile geometrically refined to perfectly match with the tweeter emission ensuring phase consistency in the crossover area.
“Boundary-Free” Rubber Surround
For improved efficiency and wider midbass frequency. (Logo Boundary Free)
Over-sized Ferrite Magnet
Combined with very low carbon content iron plates, for low distortion at high power levels.
Basket
Low mounting depth, acoustically transparent aluminum alloy basket with elegant diamond cutting and featuring the aluminum Hertz logo.
Anti-vibration Rubber Magnet Cover
To Damp Spurious Vibrations.
