Water Party
Nautic speakers deliver great sound for the festivities on any boat. Every component in the Nautic speaker line has been rigidly tested to resist the environment of fresh and salt water, including air which can lead to rust. The crossovers utilize special protective sealing lacquer and gold plated terminals to resist corrosion. From the UV resistant fiber reinforced ABS basket and grills to the V4A certified stainless steel mounting screws. Nautic speakers are shielded to prevent anything getting in, so only music can get out.
