What's in the Box:

  • 1 Speakers with grilles, pr.
  • 1 Stainless steel mounting hardware
  • 1 Foam gasket, pr.
  • 1 JBL logo 2prs
  • 1 Quick Start Guide


  • IPx5 Rated
    Marine-grade materials & components to suit the demands of a harsh outdoor environment with an IPx5 marine rating
  • Outdoor Performance
    Accentuated performance at frequencies heard in an open-air environment
  • RGB Lighting
    Multi-color RGB LED lighting engineered to withstand the harshest environment and keep the party going all night long
  • Marine Design
    Bridge mounted (grille mounted) tweeters to avoid water intrusion past the woofer cone
  • Balanced Dome Tweeters
    Weather resistant tweeters deliver a smooth high-frequency response and increased power handling for highs and mids, which equates to more lifelike sound from vocals, cymbals, brass instruments and pianos
  • Designed for the Elements
    Their one-piece polymer basket is designed to stand the test of time, even after long exposure to the sun and salt. Rubber surrounds offer superior edge protection and are much more reliable than foam. And a grille-mounted tweeter allows the front of the woofer cone to be sealed, protecting the motor structure from sea spray
  • Harman Standard Reliability Testing
    JBL speakers have to undergo a testing process that would destroy lesser speakers. JBL freezes them, bakes them, shakes them, blasts them with ultraviolet light and drives them at full power for days at a time. In the case of our marine speakers, we add salt spray and UV to ensure that they provide years of enjoyment without missing a beat
  • Individually Voiced
    For most brands, off-the-shelf speakers and a cursory approval of frequency response curves are good enough. That's not the case with JBL. We don't only listen to our speakers against the competition - we voice them against each other to ensure each line has the consistent JBL sound signature that's known and sought out by those who care about their audio. This is just part of an extensive development process undertaken by some of the best transducer engineers in the world to provide the finest listening experience at any price point
