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

1. High thermal dissipation and magnetic permeability plates, providing constant, even flux.
2. Large double magnet, for perfect control under high power, high excursion conditions.
3. Copper voice coil, wound on aluminium former, for startling thermal and mechanical capacity.
4. Back plate vent holes, for very good thermal dissipation.
5. Back Vented Spider support, for perfect symmetry under high excursion and thermal dissipation.
6. Butyl rubber gasket provides ideal coupling to the mounting surface, damping basket resonance.
7. Butyl rubber magnet ring provides protection against abrasions.
8. Internally reinforced basket, protected from abrasions by high resistance paint.
9. High current, tin-plated terminals.
10. Silver plated silicone shielded lead wires for maximum reliability and conductivity.
11. Basket and motor coupled and damped through special epoxy glue.
12. Wide-wave, resin-bonded fibre spider for mechanical reliability and consistent parameters.
13. High density Foam surround, for linear movement even under high excursion conditions.
14. Water-repellent pressed paper cone.
