Innovative technology for 3 inch compression drivers, featuring Powerful neodymium motor for minimal size and weight, allows you to keep a large voice coil without sacrificing performance.
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.
With this innovative technology, car audio enthusiasts can now build 3 or 4-Way Systems with more sound quality and performance in their vehicles.


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. The driver diameter measures only 4.88″ having enough clearance to fit inside the 5.75″ baffle cut needed for our 2″ exit horns from the WGP14-50 Series.
TRIO by PRV uses the latest Brazilian phenolic technology designed for vocal reproduction.
The phenolic diaphragm is attached to a 3″ diameter copper-clad aluminum wire with Kapton® former for a high 300 Watts RMS musical power handling, when used with recommended HPF using PRV
Digital Signal Processor DSP.
Its compact size combined with high power handling provides great output capabilities make this midrange driver one of the smallest 2” exit vocal driver in the market!
