FEATURES

• Exceptionally large neodymium magnet optimized with FEA simulations to ensure magnetic field stability even at high excursions.
• CNC-machined plates with very low carbon content for maximum magnetic permeability and low distortion at high power.
• Voice coil internal magnet with high size-to-power ratio for maximum efficiency.
• CCAW voice coil with 100 mm (4 inch) diameter capable of handling 1400 W music power, keeping operating temperature very low and minimizing dynamic compression.
• The voice coil is wound using the In/Out method to ensure even cooling of the different coil layers.
• Voice coil wound on TIL former: This fiberglass material combines the heat dissipation properties of aluminum with the stiffness of polyamide composites, ensuring uncompromising acoustic performance.
• Pole piece with "Aluminum Shorting Ring" for minimal distortion and maximum excursion at low frequencies.
• "Boundary Free" IIR rubber surround for higher SPL performance than other subwoofers with the same outer diameter.
• Exponential V-cone® with optimized geometry for high cone stiffness and high deformation resistance even at maximum excursion.
• Mineral-injected paper diaphragm for outstanding stiffness and damping.
• Acoustically very transparent, low-resonance basket made of an aluminum alloy with a self-supporting six-spoke structure and integrated ventilation holes under the spider.
• CNC-machined, elegant, diamond-cut basket edge with Hertz logo.
• Ergonomic, ultra-compact design with a range of electro-acoustic parameters optimized for sealed enclosures with volumes from 17 to 25 liters.
