Eighteen Sound 12NDA520-8 12-in Mid-low Transducer Created For Compact Reflex 2-way Enclosures And Designed To Be Coupled With Typical 1-in And 1.4-in Compression Drivers.

This item is brand-new, factory sealed.

It can also be used in mid-low applications on modern line-array systems.
Its features and design characteristics make it extremely defined in mid-range frequencies and offer a significant and consistent bottom-end, making the product also suitable for monitoring applications.
The neodymium magnet assembly developed by Eighteen Sound engineers 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 curvilinear cone, created from a high damping wood pulp, has been designed to achieve the best possible linearity within its intended frequency range.
A proprietary humidity-block cone treatment makes the transducer suitable for outdoor use in adverse weather conditions.
In addition, a special coating applied to both the top and back plates makes the 12NDA520 far more resistant to the corrosive effects of salts and oxidization.
