Hertz Energy Series 12" 700 Watt Car Subwoofer - ES3004

Hertz Energy Series 12" 700 Watt Car Subwoofer, Model ES3004

Energy ES subwoofers were designed to work best when used in small enclosures. However, their electro-acoustic parameters are optimised for use in many different enclosure types; both in terms of typology (sealed box, reflex, bandpass, etc.) and in size, insuring extraordinary versatility and performance. The use of a long excursion mobile voice coil and high flux density double magnet have created subwoofers that can stand very high power with outstanding musicality and bursting dynamics. The special anti-scratch finish and butyl rubber rings offer protection and an aggressive look.

Features

• High thermal dissipation and magnetic permeability plates, providing constant, even flux
• Large double magnet, for perfect control under high power, high excursion conditions
• Back plate vent holes, for very good thermal dissipation
• Back vented spider support, for perfect symmetry under high excursion and thermal dissipation
• Butyl rubber magnet ring provides protection against abrasions
• Internally reinforced basket, protected from abrasions by high resistance paint
• High current, tine-plated terminals
• Silver plated silicone shielded lead wires for maximum reliability and conductivity
• Basket and motore coupled and damped through special epoxy glue
• Wide-wave, resin-bonded fibre spider for mechanical reliability and consistent parameters
• High density foam surround, for linear movement even under high excursion conditions
• Water-repellent pressed paper cone
