Eighteen Sound 12NDA520 8ohm 300watt High Output MB Neodymium Driver

Eighteen Sound 12NDA520 8ohm 300watt High Output MB Neodymium Driver

Product description: 

The Eighteen Sound 12NDA520 is a 12″ mid-low transducer created for compact reflex 2-way enclosures and designed to be coupled with typical 1″ and 1.4″ compression drivers.
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-e.
Making the product also suitable for monitoring applications.
The 12NDA520 incorporates our proprietary Active Impedance Control technology (AIC), consisting of an additional coil fixed on the pole piece and connected in parallel to the moving coil.
