They are loud. They are clear. They are nearly indestructible! The KM Coaxial Marine Speakers are built to pump out the tunes and the fun - for years to come! Whether you mount your speakers in the hull or in KICKER tower enclosures, you also get a pair of stout marine-grade grilles! Our speakers are made to thrive in the water. UV treatments on injection-molded cones, Santoprene surrounds, baskets and grilles all help maintain top-shelf performance. KM speakers will endure almost any weather conditions with splash-and-spray-resistant sealed motors, cones and Locking/Sealed Terminal Covers. Speaker hardware is forged from rustproof, 316L stainless-steel.FeaturesFour-Ohm Voice Coil3/4-Inch Titanium TweeterUV-Treated Polypropylene Woofer With Santoprene SurroundUV-Resistant Polymer BasketLocking/Sealed Terminal CoverSealed Motor Structure316L Stainless Mounting Hardware IncludedCharcoal and White Grilles Included
