The SD1g attatches to glass and other non-porous surfaces using a double-sided adhesive disk (included). Each SD1g is designed for one channel of audio. An optional equilization module optimizes the SD1g for use on glass. The SolidDrive utilizes patent-pending dual-voice coil technology in an aluminum enclosure to transfer acoustic energy to any substrate with very high-powered neodymium magnets and dual symmetrically opposed motors to convert audio signals into powerful vibrations. Those vibrations are transferred into solid surfaces through direct contact. High-quality, full-range sound is then radiated from the entire surface with a frequency response of 60 Hz to 15 kHz. The symmetrically opposed neodymium magnets and specifically engineered mounting hardware results in hidden planar-source acoustics. The result is acoustical uniformity throughout the listening space.
