M3 Series 7.7" Enclosed Tower Coaxial System with Gloss White Classic Grille (M3-770ETXv3-Gw-C-Gw) (010-03266-00)

A WAKE TOWER AWAKENING

Engineered to deliver strong, smooth, crystal-clear sound that you can hear and enjoy well beyond your boat, the affordable M3 ETXv3 tower speaker system is a breakthrough in on-water audio performance.

Features:

  • Powerful midbass output in open-air applications
  • Wide range of tubular or surface-mounting options
  • Exceeds international standards for salt fog and UV exposure
  • 3-Year Warranty

Towering Performance

Robust M3 speakers are ideal for wakeboard towers or other tubular structures — or they can be flat mounted to decks and other surfaces to deliver superb sound quality with strong projected output.

DMA-Optimized Woofers

Proprietary motor, suspension and cone modeling systems are employed, resulting in reduced distortion, improved transient performance and stellar bass sound quality.

Pure Silk Tweeters

The treated silk dome design is chosen for its lightness, damping properties and smooth response characteristics to deliver superior output capability with crystal-clear, high-frequency detail.

Integrated Tweeter Filters

Each speaker includes a built-in second-order, high-pass tweeter filter with a solid-state protection circuit to minimize the possibility of tweeter failure.

Power Versatility

Designed to benefit from operation with quality amplification, M3 marine speakers are also suitable for use with standard marine head-unit power.

Real Marine Duty

For long-term use, all models are built to withstand saltwater marine environments and deliver years of listening enjoyment.
