Hertz ES 250.5 Energy Series 10" 750W SPL Subwoofer

Allowing a Higher Strength Voice Coil For a Higher Peak Power Handling!

ES 250.5 Energy 10" Subwoofer
The Hertz Energy.5 ES 250.5 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.

The implementation of the surround and spider geometry, as well as the selection of the materials used, contributed to achieving unmatched mechanical and thus acoustical linearity. This, combined with a drastic reduction of the Vas, provides the ability to achieve high undistorted SPL output in even small enclosures. The Hertz Energy.5 subwoofers are the perfect choice for solid, powerful bass in perfect harmony with improved vehicle integration.

Features:

• V-cone® technology with water-repellent paper membrane, for reduced moving assembly mass and increased sensitivity.
• Wide-wave spider profile, for high mechanical resistance against impulsive stresses; its resin-bonded fibre ensures consistent electro-acoustic parameters in time.
• High-density foam surround, for extreme mechanical and acoustical linearity, even under high excursion.
• 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.
• Silver-plated silicone-shielded lead wires ending with tin-plated, high-current terminals for high resistance against mechanical stress and low contact resistance.
• High magnetic permeability plates and large magnets, ensure a constant and even magnetic flux, for perfect low-frequency control.
• Butyl rubber gasket and magnet protective cover, provide ideal coupling to the mounting surface, damping basket resonances.
