Acoustically optimized metal solutions for loudspeakers
Speaker grilles must accomplish two things at once: they should not compromise sound quality while reliably protecting the internal components, and they must have a high-quality appearance that enhances the speaker’s design.
Perforated metal sheet is the ideal solution for this: it can be precisely perforated, is durable, dimensionally stable, and highly versatile in design. Graepel combines modern perforation technology, design development, and surface finishing to create speaker grilles that optimally combine acoustics, design, and protection.
Graepel ventilation grilles with up to 80% open area ensure optimal sound performance in audio applications.
Graepel Percus enables the precise reproduction of digital image data as high-quality perforated metal panels. By carefully varying the hole sizes and spacing, a technically defined grid is created that faithfully reproduces images, graphics, or logos on metal surfaces.
