The SolidDrive MSK-1-T Surface Mount Actuator with Transformer is a professional hidden sound transducer designed for commercial sound masking systems installed behind drywall walls and ceilings. Instead of using a conventional loudspeaker cone and visible grille, the MSK-1-T transfers acoustic energy directly into the drywall surface, allowing the surrounding material to radiate masking sound into the room.
Designed for installations where discreet audio coverage and architectural appearance are important, the MSK-1-T provides a concealed solution for offices, conference facilities, corporate buildings, and other commercial environments requiring sound masking.
The actuator features a rugged anodized aluminum housing, neodymium magnet technology, and an integrated 10-watt transformer for 70V distributed audio systems. Its planar-source design helps distribute sound over a broad area, providing consistent masking coverage when properly installed and equalized.
The SolidDrive MSK-1-T is intended for installation using a compatible SD1 drywall mounting bracket, sold separately. The bracket maintains the mechanical contact needed to transfer sound energy into the drywall surface.

Hidden Sound Masking Through Drywall
The SolidDrive MSK-1-T uses a different approach from conventional sound masking speakers.
Traditional loudspeakers produce sound using a moving cone. The MSK-1-T instead transfers mechanical energy into a drywall panel, allowing the panel itself to radiate sound.
Because the actuator is installed behind the surface, the finished room does not require a visible loudspeaker grille.
This approach is particularly useful for commercial facilities where sound masking is needed without disrupting the architectural appearance of walls and ceilings.
The MSK-1-T is designed to operate as part of a complete sound masking system, helping reduce the intelligibility of nearby conversations when properly configured.
Integrated 10-Watt Transformer for 70V Systems
The MSK-1-T includes a built-in 10-watt transformer designed for connection to compatible 70V audio distribution systems.
This allows multiple sound masking actuators to be connected to a properly designed constant-voltage amplifier system.
The transformer makes the MSK-1-T suitable for commercial installations where sound masking equipment is distributed across multiple rooms or areas.
For proper operation, the connected amplifier, transformer settings, and overall system load must be matched according to the manufacturer's installation requirements.
The MSK-1-T is a passive transducer and requires an appropriate amplifier and sound masking signal source.
Designed for Concealed Drywall Installation
The SolidDrive MSK-1-T is designed for installation behind drywall walls and ceilings.
A compatible SolidDrive SD1 mounting bracket holds the actuator against the drywall surface, maintaining the contact pressure needed for efficient sound transmission.
Available mounting accessories include:
- SD1-BR12: Bracket assembly for 12-inch on-center framing.
- SD1-BR16: Bracket assembly for 16-inch on-center framing.
- SD1-BR24: Bracket assembly for 24-inch on-center framing.
- SD1-BR16-R: Rear-install drywall bracket assembly for compatible installations.
Important: The required drywall mounting bracket is sold separately and must be selected according to the installation.
Broad Sound Coverage for Commercial Spaces
The MSK-1-T is designed to distribute masking sound across a wide area using the drywall surface as the sound-radiating element.
The manufacturer specifies a 120-degree coverage angle at 2 kHz.
Unlike conventional speakers that direct sound outward from a visible driver, the SolidDrive system creates a distributed sound field through the material to which it is attached.
This makes it useful for installations where discreet sound coverage is preferred.
Actual sound coverage and frequency response depend on the drywall construction, mounting location, acoustic conditions, and system equalization.
