Designed for motorcycles and more Wet Sounds' goal when creating these ZERO Series marine speakers was to match the performance of their famous REV Series tower speakers but design them for use where big speaker pods can't go. Why "ZERO?" Wet Sounds says that's how many compromises they made in crafting these exceptional speakers for use in motorcycles, powersports vehicles, and boats. Big sound for the outdoors With power-handling up to 100 watts RMS, these 6-1/2" marine speakers prioritize cooling for hours of performance. A horn-loaded tweeter ensures that your music's finer details aren't lost amid all the sounds of the great outdoors, and the specialized polypropylene cone delivers lows that resonate in spite of road and engine noise. Wet Sounds also keeps things flexible with their twist-lock grilles, so you can easily remove them if you don't need them. Protected against the weather When it comes to outdoor-friendly gear, you'd expect a company with "Wet" in its name to know a thing or two. And these speakers are further proof that Wet Sounds really knows all-weather audio. Their exclusive Nylas(tm) (a combination of nylon and fiberglass) speaker frames and grilles are tough enough to withstand the elements.
