TS-ME650FS Marine Grade ME-Series 2-Way Coaxial Speaker. (250 W) Features: ME-Series Marine Entertainment Combining Pioneer Sound Quality with All-Weather Durability. Pioneer's ME-series marine speakers are protected from the effects of sun and water exposure, meeting both IPX7 & ASTM D4329 to achieve all-weather reliability. Utilising a Mica reinforced IMPP(TM) monocoque cone and a butyl rubber surround, they are constructed using advanced in-mould bonding techniques, meaning they have superior water resistance whilst maintaining high quality and a powerful sound. Internally, a symmetrical motor design combined with high strength suspension optimises stability, linearity and clear, low distortion sound reproduction. For the most natural sound, they also feature a lightweight polyimide (PI) tweeter diaphragm and uniquely shaped wave guide to provide natural, clear vocals with wide dispersion. Great for a really natural wide sound area. The TS-ME650FS comes with both white and black pearlescent sports grills, so you can match your cabin interior and lifestyle.
