  • M6 6.5-inch marine coaxial speaker (75 W, 4 Ω) - gloss white trim ring, gloss white classic grille, black tweeter mesh
  • Designed and built specifically for marine use, the M6 coaxial systems deliver maximum audio performance in any open-air boating environment.
  • A DMA-optimized woofer design with long excursion and excellent power handling ensure your music comes through loud and clear at high speed or at anchor.
  • A 0.8-inch pure silk tweeter, specially treated for the marine environment, handles the high-frequency duties. You'll appreciate the clean, articulate high-frequency response of the M6 dome tweeter, especially at higher volumes.
  • The woofer enclosure houses a true passive 2-way, multi-order crossover that is protected from vibration and corrosion. Also included is an automatic solid-state tweeter protection circuit to minimize the possibility of tweeter failure.
  • Although M6-650-X coaxial systems can be used with as little as 25W per channel, we recommend amplifiers with a continuous output of between 75 and 150W per channel for optimum audio performance.
  • All M6 speakers are manufactured at JL Audio's facility in Miramar, Florida using global components and materials.
  • Sold as a pair.
