Large double magnet, for perfect control under high power, high excursion conditions. Copper voice coil, wound on aluminium former, for startling thermal and mechanical capacity. Back plate vent holes, for very good thermal dissipation. Back Vented Spider support, for perfect symmetry under high excursion and thermal dissipation. Butyl rubber gasket provides ideal coupling to the mounting surface, damping basket resonance. Butyl rubber magnet ring provides protection against abrasions. Internally reinforced basket, protected from abrasions by high resistance paint. High current, tin-plated terminals. Silver plated silicone shielded lead wires for maximum reliability and conductivity. Basket and motor 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.
