Thunder Marine wakeboard speakers are designed to withstand almost anything Mother Nature can throw at them.  Featuring weather resistant polypropylene cones and teteron tweeters these speakers are extremely mositure resistant.  Each speaker utilizes a sealed PVC basket to ensure moisture is kept out of the motor structure and an ASA plastic grille that is both impact and UV resistant.  All hardware is either stainless steel or gold plated to protect against corrosion and maximize performance.  Each wakeboard speaker is designed to mount to any wakeboard tower measuring between 2.25" and 3".  The speaker can is a rotationally molded, polyethylene resin that is waterproof and UV resistant with all speaker connections on the inside minimizing the chances of corrosion.  These speakers are ideal for wakeboard boats but are also suited to pontoon boats, fishing boats, and even UTV's like the MTX Hammerhead buggy pictured to the left.
