Key Features:

• The (Eighteen) 18 Sound 15ND830 is a high power, high output, low frequency woofer meeting the most stringent requirements in high quality professional transducers.
• Thanks to its versatility, the 15ND830 can be used in 2-way compact reflex enclosures and reflex / band pass subwoofers.
• The neodymium magnet assembly assures high flux concentration, low power compression and excellent heat exchange, since the external magnet configuration is considerably more efficient than traditional under-pole magnet topology.
• This results in high levels of force factor and power handling with an optimum power to weight ratio.
• The direct contact between the heat sink and basket, together with the magnetic structure, represents a fundamental improvement in thermal connection and heat dissipation.
• Hence, power handling capabilities are increased and power compression lowered.
• The deep profile curvilinear cone, created 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 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 fiberglass former which improves force transmission and thermal power handling.
• A special coating applied to both the top and back plates makes the 15ND830 far more resistant to the corrosive effects of salts and oxidization.
