SoundTube SD1 
Solid Drive Speaker

Solid Drive Speakers
Hear great sound without visible speakers. SolidDrive's patented transducer technology can turn almost any drywall glass wood ceramic or laminate surface into a speaker. With no visible grilles or wires it's perfect for retail showrooms restaurants trade shows hospitality and boardrooms.

  • Proprietary dual-voice coil technology in a durable aluminum enclosure delivering high power handling and sensitivity across multiple substrates.
  • Symmetrically opposed neodymium magnets convert audio signals into acoustical energy for any rigid surface including glass drywall ceramic and wood.
  • Hidden planar-source audio technology evenly distributes acoustic energy throughout the listening space.
  • Proprietary behind-surface mounting technologies ensure maximum visual appeal.
  • 88.5 Max SPL (drywall) and 120° dispersion pattern across the upper registers of the frequency spectrum.
  • SD1 optional accessories: self-leveling constant tension pre-construction bracket to ensure proper alignment & wall contact.
  • Optional accessories include passive EQ module; 20 Watt metal junction box for 25 70.7 & 100 Volt applications (AC-JB20-XFMR) and Heat Sink Fins
  • For extended frequency response couple SolidDrives with SW7 or SW8 subwoofers.
  • SolidDrives operate in a virtually friction-free environment and are engineered for infinite life. SolidDrives come with an industry-leading 7-year warranty.
  • UL approved 1480 and 2043.
