Marine Grade Protection / IPX Rating LIFE SHIELD: Protected for water and dirt. UV protected against sun fade. 72 Hour UVA Burn In Certified. IPX68 rated. Tweeters A 1 inch Titanium Dome tweeter utilizing Waterproof Coated Silk Surround. The result of this configuration is natural sounding high frequency response while producing high volume (SPL) without the typical harshness or distortions which can occur at higher listening levels. Cone Material Injection Molded Composite Polypropylene Cone: Delivers impactful bass with minimal cone flex which can cause distortion or sloppy bass. Surround / Cone Coupling Co-Molded Santoprene™ Surrounds: The cone and surround are coupled in such a way to maximize bass frequency power while remaining impervious to the outdoor environment including colder weather. Gasket Molded Polymer Sealing gaskets are utilized to keep the speaker isolated from the mounting surface and improve protection from water intrusion. Spider An Aramid fiber composite spider is used to stabilize the cone and voice coil in all musical situations. Aramid fibers do not degrade over time and are not susceptible to temperature swings. Cooling System Front and rear venting allows air passage through the spider and back plate to exchange air over the voice coil. Crossover Butterworth 12dB per octave crossover with PTC (Positive Thermal Coefficient) tweeter protection. Frame Composite (UV Resistant ASA + Fiberglass) Frames are incredible strong and lightweight, but most important for music they are inert, meaning they have no resonance frequency, this assures all music and minimal distortion. Motor The tweeters feature High-Energy N38H Neodymium Motors: The Neodymium magnet is the strongest magnet that can be used while remaining very light-weight. The midwoofer utilizes a High-Energy Ferrite Magnet which allows the magnetic energy to react quickly making the bass sound fast and tight. Connectors Real 10 Karat Gold plated, water resistant connectors provide protection against rust and corrosion. Grills PERSONALIZED FINISH: The Nautic Premium marine and off-road vehicle waterproof speakers are finished in a hardened composite with their color inspired by the black sand beaches of Kaimu Hawaii. Each speaker includes three different grills. Kaimu Black, Miami Silver and Bahama White. Many enthusiasts use the white insert to lightly sand and paint to match their personal style and vehicle.
