PRW 50

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 has been fitted with a 19 mm voice coil and has a paper cone in a glass-fiber reinforced polyamide basket - ideal for universal installation thanks to its small installation dimensions. The set includes two powder-coated metal brackets that enable plug & play installation in various Mercedes-Benz, Toyota and G.M. General Motors models. The PRW 50 is also suitable for standard 4-point mounting - as the retaining ears and mounting points can be easily adjusted.
