SolidDrive patented technology transforms any solid surface (like drywall, glass, wood, or fiberglass) into a sound source. SolidDrive directly transfers acoustic energy to the surface its mounted to, creating a large and dynamic sound field. With no visible wires or grilles, SolidDrive gives you the freedom to have Sound without Speakers. Since SolidDrive resonates over a large surface area, the loss of volume over distance is roughly 35% less than with conventional speakers. This low distance factor, combined with SolidDrives 120? ultrawide coverage angle, creates remarkably even sound coverage throughout the entire space while meeting UL1480 and UL2043 safety standards.
