Description
Download Manual The SD-1-T is a titanium-finished contact transducer designed to convert electrical audio signals into mechanical vibrations that radiate through solid surfaces. It is engineered to deliver full-range sound across walls and ceilings by turning the mounting surface into a uniform radiating plane. This unit is intended for single-channel installations and integrates into architectural surfaces for hidden audio distribution.
SolidDrive dual-voice coil technology and symmetrically opposed motors provide balanced planar excitation across a broad frequency range. The aluminum enclosure houses high-powered neodymium magnets that maximize coupling efficiency to substrates. The result is broad, even sound radiation from the entire treated surface rather than a single point source.
Performance spans 70 Hz to 15 kHz ensuring clear midrange and articulate highs for music and spoken word. Each SD-1-T is rated for one audio channel and can be paired with an optional 10 W transformer for line-voltage distributed systems. The design emphasizes consistent surface uniformity and hidden planar-source acoustics for a seamless listening environment.
Connectivity is straightforward – the transducer mounts directly to drywall or other substrates and interfaces with standard amplifier outputs or line-level distribution via the transformer option. No special cabling is required beyond speaker wiring and optional transformer hook-up for impedance matching. The unit is compatible with typical audio amplification systems used in commercial and architectural audio deployments.
Typical applications include distributed background music systems, foreground paging, and immersive installations where visible speakers are undesirable. The SD-1-T performs well in retail spaces, hospitality venues, and corporate interiors where discreet coverage and even sound distribution are priorities. It provides room-filling sound by leveraging the entire surface as the radiator.
Installation uses the patented cantilever spring mounting bracket for secure attachment in walls and ceilings and engineers recommend testing on the intended surface before final installation to optimize coupling. The product meets UL1480 and UL2043 safety standards and is TAA and BAA compliant. Robust construction and neodymium motor assemblies ensure long-term reliability and consistent tonal performance.
