PRW 50 by ETON Description
The PRW 50 from Eton is a 2-inch midrange driver specifically designed for a wide range of vehicle models from Mercedes-Benz, Toyota, and General Motors. This speaker features a 50 mm paper diaphragm and a robust 19 mm voice coil. Thanks to its fiberglass-reinforced polyamide basket and the included powder-coated metal brackets, an easy plug & play installation is possible. With an impedance of 4Ω and a power handling of 15W (RMS), the PRW 50 offers clear sound and efficient installation. The strong neodymium magnet and its compact design make it a versatile addition to your vehicle. The product is developed and manufactured in Germany.
With the newly developed PRW 50, there is finally a suitable sound upgrade for various Mercedes-Benz, Asian, and U.S. American vehicle models. The modern 50 mm (2") full-range speaker is equipped with a 19 mm voice coil and features a paper diaphragm in a fiberglass-reinforced polyamide basket – ideal for universal installation due to its small installation size. The set includes two powder-coated metal brackets that allow for a plug & play installation in various Mercedes-Benz, Toyota, and G.M. General Motors models. The PRW 50 is also suitable for a standard 4-point mounting – as the mounting ears and points can be easily adjusted.
