Subwoofer hertz sx 300d / subwofer hertz spl 12 inch

Hertz SX 300D SPL SHOW
12" Dual Coil Voice Subwoofer with Dynamic bass ( double magnet )
3200 watts

Fitur & Spesifikasi produk :
The Hertz SPL Show SX 300d 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 sx 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.
