Built to survive freezing temperatures, snowstorms, and melt cycles, this speaker grille system protects your audio investment while preserving high-frequency sound clarity—ideal for alpine rooftops, ski resorts, and winter AV setups.

✅ Product Attributes (Plain English, No Table)

• Outer faceplate made of 1.8 mm thick 6060-T6 aluminum with 4 mm perforations on 9 mm staggered pitch, delivering ~48% open area.

• Hydrophobic stainless-steel inner mesh resists moisture adhesion and supports passive snow drainage via engineered frame slots.

• Surface powder-coated in glacier white (UV-stable) to visually harmonize with alpine architecture and snowy terrain.

• Acoustic transparency tested under ASA protocols: <0.7 dB insertion loss from 200 Hz–18 kHz, even in icy or wet conditions.

• Environmental durability tested to ISO 9227:2022 and ASTM B117 salt spray for alpine corrosion resistance.

• Snow and wind exposure loading compliant with ASCE 7-22 for rooftop or façade installations.

• Features meltwater evacuation channels and snow-shedding textures that prevent ice crust formation.

• Mounting systems reuse existing brackets with minimal disruption to structures—ideal for AV retrofits.

• Validated in a real-world Swiss ski resort: +3.0 dB clarity boost in 8–12 kHz band and 78% fewer winter service calls.

• Engineered for extreme winter events, hotel terraces, snow parks, and high-elevation acoustic systems.
