describe

The X Series is designed for extreme outdoor environments and is tailored for outdoor cultural tourism projects and large-scale public address systems.

1. By combining a reinforced fiberglass (FRP) coated enclosure with composite waterproof coating technology, it delivers a professional audio solution that offers a three-in-one protection against water, impact, and corrosion.

2. Whether facing torrential rain, sandstorms, or salt fog corrosion, it consistently delivers pristine sound, redefining the standards for durability and audio quality in outdoor sound systems.

3. Industrial-grade materials, featuring epoxy resin and high-density fiberglass laminate construction, deliver a 300% increase in impact resistance.

4. Sealed construction with reinforced waterproof coatings at vulnerable seams and an internally reinforced frame design achieves IP66-rated water and dust resistance.

5. Corrosion-resistant and certified to pass the ISO standard 2000-hour salt spray test, it withstands acid rain, seawater, and corrosive gases from chemical plants.

6. Water- and dust-resistant, with a wide operating temperature range from -20°C to +100°C (passed 72-hour high-low temperature cycling tests).

7. Wind and sand resistance, compliant with MIL-STD-810G dust protection standards, suitable for desert and mining environments.

8. Designed for outdoor cultural tourism projects, high-end entertainment venues, and large-scale public address systems.
