Key Features: 

• The Eighteen Sound 15ND930 is a high power, high output, extended low frequency neodymium transducer which meets the most stringent requirements in high quality professional transducers.
• Also a high level of performance and sound quality have been achieved by exploiting the most advanced technologies available today.
• Thanks to its versatility, the 15ND930 can be used in 2-way compact reflex enclosures with a 1.4″ compression driver, in multiway systems and in high loading sub woofers as small as 70 lt (compact reflex, bandpass and horn loaded configurations).
• 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 large heat sink and basket, together with the magnetic structure, represent a fundamental improvement in thermal connection and heat dissipation.
• Hence, power handling capabilities are increased and power compression lowered.
• Additionally a  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.
• Mainly, the cone surround, made from a linen material is highly resistant to aging and fatigue.
• Important, the in-house developed cone treatment is a humidity repellent and significantly dampens bell mode resonances.
• The 3”, 75 mm  copper edge-wound voice coil assembly is wound on a strong fiberglas former to improve force transmission and power handling.
• Further already low distortion and sound quality are further improved by Double Demodulating Rings (DDR) that flatten impedance and phase with a constant power transfer.
• A special coating applied to both the top and back plates makes the 15ND930 far more resistant to the corrosive effects of salts and oxidization.
• The 15ND930 16ohm is an ideal replacement speaker for Mackie SR1530
