CONE: Made from polyurethane, the MRWT40 4-inch marine waketower speakers provide a resilient and durable material that can offer great sound with the advantage of long-lasting speakers

VOICE COIL: Our voice coils are able to withstand high temperatures yet maintain its strength and fatigue properties. This gives our speakers the advantage of longer play times with lower weights

SURROUND: Rubber has the ability to endure much punishment without any sign of damage. It complements the whole structure of the speaker by allowing constant abuse where it is most needed, without the wear and tear

TWEETER: The dome shape radiates sound with a wider dispersion pattern than the semi-dome design. Since high-frequency sound waves are very directional, a wider dispersion of the sound waves will give you a larger "sweet spot"

WEATHERPROOF: The MRWT40 has been outfitted with the latest weatherproofing techniques for protection against the elements

SPECS: Impedance - 4 Ohms, Frequency - 130 Hz to 20 kHz, Dimensions - 7.1" x 5.4" x 7.1", Weight - 5.9 lbs. Polypropylene Woofer Cone and Rubber Surround
