They’re completely waterproof, thanks to the heavy duty ASB construction. And they’re powerful – 300 watts max. A 3.5” aluminum injection cone woofer provides the midbass, while a 1” high compliance Mylar tweeter pushes sweet highs. A capacitor crossover network separates these two channels discretely for a brilliant sound. The bass reflex vent boosts the bass response for a deeper, more powerful sound, ultimately delivering a frequency response of 60 Hz to 20 kHz. Mount using the unique spring loaded mounting system. The mesh grills are rustproof and removable. Sold as a pair.
