12ND730 Driver 12inch Neodymium 400W 8Ω 18 Sound

This results in high levels of force factor and power handling with an optimum power to weight ratio. The deep profile curvilinear cone, made from a special high strength wood pulp has been designed to achieve the best possible linearity within its frequency range. The cone surround made from a linen-like material is highly resistant to aging and fatigue. The in-house developed cone treatment is fully water repellent and also gives a significant degree of rigidity to the cone. The 75 mm Interleaved Sandwich Voice coil (ISV) assembly is wound on a strong fiberglas former that improves force transmission and thermal power handling. The 4 threaded backplate holes give the user the possibility to insert an external-customised heat sink if further heat dissipation is required. A special coating applied to both the top and back plates makes the 12ND730 far more resistant to the corrosive effects of salts and oxidization.
