Extremely resistant to moisture, corrosion, and heat, these specially designed marine and outdoor speakers deliver rich, dynamic sound both on the water and in outdoor environments. The water-resistant IMPP composite cone provides excellent mid and low-frequency reproduction and withstands the effects of saltwater, humidity, and extreme heat. The elastomer surround is resistant to discoloration and deformation. A fiberglass-reinforced AES basket effectively protects the magnet assembly, and the pure white AES grilles are long-lasting light-stable and do not warp even under high heat. Corrosion-resistant gold connection wires and gold-plated contacts ensure interference-free signal transmission and thus maintain high sound quality over the long term.
