Solid Drive

SolidDrive is a powerful hidden sound transducer that transmits acoustical energy through almost any solid surface. The entire surface becomes a speaker delivering high-quality sound and the frequency response of conventional diaphragm speakers. SolidDrive provides a distinct advance for audio systems used in home theater systems, distributed audio, and other high-performance audio applications. SolidDrive works with rigid surfaces that include glass, drywall, granite, metal, wood, ceramic, laminates and composites. Because the SolidDrive utilizes materials already existing in a room, its ideal for installed home audio, commercial audio, or a home theater system anywhere an invisible sound source is needed.

How it works:

SolidDrive is a patented technology that utilizes very high-powered neodymium magnets and dual  symmetrically opposed motors to convert audio signals into powerful vibrations that are transferred into solid surfaces by direct contact. High quality, full range, hidden sound is then  radiated from the entire surface with a frequency response of 60 Hz to 15 kHz.
