Redefining Poolside Sound: Acoustic Transparent Grilles for Bluetooth Speaker Protection

Use Case: Fading Sound and Short-Lived Grilles at a Luxury Pool Deck

An upscale resort in Bali faced constant speaker failures around its poolside lounge areas. Traditional plastic mesh covers cracked under sun exposure and trapped moisture, leading to muffled audio output and mold accumulation. Guest satisfaction dropped during events, especially with wireless Bluetooth systems used for ambient music.

The resort’s engineering team partnered with us to develop a long-life, acoustically optimized speaker grille that could handle sun, water, and sound pressure without distortion.

Material Design and Engineering

The solution was a custom-designed perforated aluminum grille, made from 5052 marine-grade alloy. Featuring 0.9 mm holes spaced at 1.8 mm, the sheet had a 38% open area and hydrophobic PTFE nano-coating. These specs preserved Bluetooth audio clarity while shedding water droplets instantly.

We aligned the design with ASTM G154 UV testing and ISO 9227 salt spray standards. See more structural parallels from Anti-Slip Panels.

Installation Innovations

To prevent vibrations on bass-heavy tracks, we used silicone gasket mounting between grille and speaker shell. Heat expansion was accounted for with floating frame slots. Based on ASCE Acoustic Design Guidelines, the panel was spaced 2 mm from the diaphragm to avoid back pressure.

Additional inspirations were taken from Acoustical Society of America and design features reviewed by Architectural Digest.

Case Impact: Audible and Operational Gains

• Sound transmission improved by 44% in blind A/B tests

• No material degradation after 6 months of sun and water exposure

• Bluetooth pairing remained stable due to minimal signal shielding
