Highly sensitive speaker
One-piece basket withstands corrosive elements
180-watt peak power handling
JBL's MS6520 speaker is designed with a polypropylene cone that provides more overall speaker-cone area for higher sensitivity, increased low-frequency output, and greater musical character. Weather-resistant tweeter delivers a smooth high-frequency response and increased power handling. One-piece polymer basket is designed to stand the test of time, even after long exposure to salt and sun. 180-watt peak power. 4 ohm impedance. Includes speaker wire, stainless steel mounting hardware, and owner's manual.
Plus One Woofer Cones
Provide more overall speaker-cone area than other cones, which results in higher sensitivity, increased low-frequency output, and enhanced music.
Balanced Dome Tweeters
Weather-resistant design delivers smooth high-frequency response and increased power handling for highs and mids to produce more lifelike sound from vocals and instruments.
Designed For The Elements
One-piece polymer basket withstands exposure to sun and salt. Rubber surrounds offer edge protection and are more reliable than foam. Grille-mounted tweeter allows the front of the woofer cone to be sealed against sea spray.
JBL approves each speaker's frequency response curves and voices their models against each other to ensure each line has a consistent sound for the finest listening experience.
