FEATURES

•   Exceptionally large neodymium magnet optimized with FEA simulations to ensure magnetic field stability even at high deflections.
•   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/power ratio for maximum efficiency.
•   100 mm (4") diameter CCAW voice coil capable of handling 1400 W of music power, keeping operating temperatures very low and reducing dynamic compression to a minimum.
•   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 glass fiber material combines the heat dissipation properties of aluminum with the rigidity of polyamide composites for uncompromising acoustic performance.
•   Center pole with "Aluminium Shorting Ring" for minimal distortion and maximum extension 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 deflection.
•   Paper membrane injected with minerals for superior stiffness and damping.
•   Acoustically very transparent, low-resonance basket made of an aluminum alloy with a free-standing six-spoke structure and integrated ventilation holes under the spider.
•   CNC machined elegant diamond cut basket rim with Hertz logo.
•   Ergonomic, ultra-compact design with a set of electro-acoustic parameters optimized for closed enclosures with a volume of 17 to 25 liters.
