Dual-Layer Water-Filtered Acoustic Transparent Speaker Grille

Designed for outdoor sound systems exposed to water, mist, and humidity, this grille merges high-performance acoustic transparency with reliable moisture protection. With a precision-perforated aluminum panel and an internal fog-resistant mesh layer, it ensures consistent sound quality and marine-grade durability in demanding environments.

✅ Product Attributes (Plain English, No Table)

• Outer layer made from 2 mm thick 5052-H32 aluminum with 4 mm round holes at 50% open area.

• Coated with UV-stable marine-grade powder finish for long-term exposure.

• Internal water-filter mesh crafted from stainless steel, treated with a hydrophobic nanocoating to resist mist and fine droplets.

• Minimal insertion loss (<0.6 dB) across 250 Hz–15 kHz range as tested under ASA standards.

• Designed and simulated using acoustic CFD modeling for accurate open-air performance.

• Complies with ASTM B117 corrosion testing and ISO 9001-certified manufacturing.

• Wind-load and thermal behavior validated to ASCE architectural exposure criteria.

• Flush-mounted design with color-matched finish for luxury integration.

• Reduces water-related driver failure, eliminates rust streaks, and minimizes sound scattering.

• Proven 12-month durability in resort settings with zero failures and improved treble clarity (+3.1 dB @ 6 kHz).

• Ideal for high-humidity venues: resorts, fountains, spas, coastal bars, and yacht decks.
