SoundTube SD-1SM Titanium Wood Surface-Mount Actuator

The SD-1SM Titanium is a patented dual-voice coil transducer engineered to attach directly to wood and similar substrates using included countersunk wood screws. Housed in an anodized aluminum enclosure with a titanium finish, it transfers audio signals into deep, full-range vibrations.

With high-powered neodymium magnets and symmetrically opposed motors, the SD-1SM produces uniform planar-source acoustics across the entire mounting surface. Its precision mounting hardware ensures discreet installation and consistent sound dispersion from 60 Hz to 15 kHz.
