Show original supplier description
The Kicker 49KM604W coaxial marine speaker delivers stellar full-range sound, engineered to thrive in marine conditions for years. Its construction features a UV-treated polypropylene woofer with a Santoprene® surround and a PEI dome tweeter for spectacular highs and smooth, impactful midrange. Built to exceed industry standards, these speakers are ASTM tested for UV and salt/fog exposure. UV treatments are applied to the cones, surrounds, baskets, and grilles to ensure longevity. Rustproof 316L stainless steel hardware is included, and the white grille and basket are designed to prevent yellowing or fading over time. Locking terminal covers further enhance their durability in harsh environments. For optimal performance, the Kicker 49KM604W speaker works best with 15-50 watts of recommended RMS power, handling up to 150 watts of peak power. The speaker has a rated impedance of 4 ohms, a sensitivity of 90 dB, and a frequency response of 35-21,000 Hz. Mounting dimensions include a hole diameter of 5-3/16 inches and a mounting depth of 2-1/2 inches.
