optimized steel grid pattern Along with its optimum perforation coefficient, got through resistance versus performance mathematical calculations, the proprietary round grid pattern is designed to provide both protection to the speakers and acoustically transparent sound. A heavy-duty 1.5 mm steel grille protects internal components from the hard road use.
