The Revolution™ Series uses our proprietary REV TEC™ technology.  Unlike most conventional designs, REV TEC technology provides remarkable volume and amazing full range sound quality on axis and off axis at long distances. Extensive acoustic testing has confirmed these speakers ability to project volume at 80 feet and beyond without any loss of detail or information.  Not only does the Revolution series achieve volume and sound quality at a minimum of 80 ft, but with the REV TEC technology the rider can enjoy quality sound while riding outside the wake and being almost parallel to boat. Available with a MC Mount, X Mount, Fixed Clamp or Swivel Clamp
