The D3220Ph-Nd is our best driver for vocal reinforcement in car audio systems due to its impressive power-to-size ratio and ability to deliver low midrange response from 650 to 7,500Hz, pure midrange vocal reproduction. The D3220Ph-Nd neodymium phenolic compression horn driver, offers the best performance for size ratio, features a powerful neodymium magnet motor. This allows you to use this horn driver in custom doors and stuntwall systems for vocal reinforcement. We have created a compact and powerful driver that solves the critical component spacing and weight issue in large systems. The special diameter allows front mounting, making it easy to install, without detaching the driver from any WGP14-50 Horn.
