•   CONCENTRIC COAXIAL TWEETER: Integrated into the woofer's voice coil, it creates a single radiation point to create a virtual soundstage like a live music performance.
•   TWEETER SUPPORT THAT WORKS AS A REAR CHAMBER: It is designed to have a low Fs to ensure a well-damped high pass and allow a low crossover frequency.
•   36 MM PURE COPPER WOOFER VOICE COIL: wound on a polyamide coil former for excellent power handling and dynamic, compression-free reproduction.
•   PRESSED PULP CONE WITH COTTON FIBERS: combines rigidity and lightness for a wide frequency response. Geometrically refined cone profile that is perfectly matched to the tweeter and ensures phase consistency in the transition area.
•   "BOUNDARY FREE" RUBBER SURROUND: for improved efficiency and a wider mid-bass range. (Boundary Free logo)
•   OVER-SIZED FERRITE MAGNET: combined with very low carbon iron plates for low distortion and high performance.
•  BASKET: Low installation depth, acoustically transparent basket made of aluminum alloy with elegant diamond cut and with the aluminum Hertz logo.
•   ANTI-VIBRATION RUBBER MAGNET COVER: to dampen annoying vibrations.
