Engineered for alpine resilience, this two-layer acoustic grille protects speakers from snow buildup, ice infiltration, and thermal shock—without sacrificing audio clarity. Designed for harsh winters and high-altitude AV systems.

✅ Product Attributes (Plain English, No Table)

• Built with 2.0 mm perforated 5052-H38 aluminum (4 mm holes, 10 mm staggered, 48% open area) for acoustic transparency and snow impact resistance.

• Internal hydrophobic 316 stainless steel mesh coated with nano-layer to prevent moisture retention and freeze penetration.
