Subwoofer hertz es 250d.5 / subwofer hertz doublecoil 10" / hertzes250

Hertz ES 250D.5 10" Dual Coil Voice Subwoofer with Dynamic bass ( Vcone & Klippel TM Technologies ) Fitur & Spesifikasi produk : The Hertz Energy.5 ES 250D.5 car audio subwoofers offer a dynamic bass and are capable of outstanding SPL never achieved in this category of the market. The introduction of the V-cone technology had a big impact in the efficiency of the ES.5 subwoofers, also improving cone stiffness and reducing the weight of the moving assembly, allowing a higher strength voice coil for a higher peak power handling. 1. V-cone technology with water-repellent paper membrane, for reduced moving assembly mass and increased sensitivity. 2. Wide-wave spider profile, for high mechanical resistance against impulsive stresses; its resin-bonded fibre ensures consistent electro-acoustic parameters in time. 3. High density foam surround, for extreme mechanical and acoustical linearity, even under high excursion. 4. Copper voice coil wound on aluminium former, combined with the spider support cooling system and bottom plate vent holes, for outstanding thermal capacity in power peaks. 5. Silver plated silicone shielded lead wires ending with tin-plated, high current terminals, for high resistance against mechanical stress and low contact resistance. 6. Dual voice coil configuration, to maximize the amplifiers achievable power and improve connection versatility. 7. High magnetic permeability plates and large magnet, ensuring a constant and even magnetic flux, for perfect low frequency control. 8. Butyl rubber gasket and magnet protective cover, provide ideal coupling to the mounting surface, damping basket resonances.
