Cambridge Sound DSMSK1 MSK-1 Solid Drive Sound Masking Speaker for Drywall - 911.0849.900

Product Overview

The Cambridge Sound DSMSK1 (part number 911.0849.900) is the SolidDrive MSK-1, an economical hidden planar-source sound transducer designed for sound masking in drywall applications. Instead of mounting a visible speaker, the MSK-1 attaches behind the wall surface and drives the drywall itself, turning the wall into the masking radiator. It uses technology similar to SolidDrive's patented SD1 transducers, housed in a rugged aluminum enclosure with neodymium magnets. The result is wide, even audio coverage and acoustical uniformity in the listening space with no visible hardware.

Product Description

While ceiling emitters are the usual loudspeakers of a sound masking system, some spaces — hard-lid ceilings, historic interiors, or design-sensitive rooms — cannot accept visible ceiling devices. The MSK-1 addresses these conditions by transferring acoustic energy directly into the drywall substrate, which then radiates the masking signal across a broad planar surface. Driving a large surface instead of a small cone yields extremely wide, even coverage and acoustical uniformity, reducing the hot and cold spots that point-source speakers can create. The transducer's aluminum enclosure and neodymium magnet structure are built for concealed, long-term installation inside wall cavities. The MSK-1 must be installed using the SD1 mounting bracket, sold separately; bracket widths are available to match common in-wall stud spacing. As a fully hidden device, it preserves architectural finishes while delivering speech-privacy masking to the occupied space. Pair it with masking generators and amplifiers from the Cambridge Sound collection.

Key Features

• Completely Hidden Installation — mounts behind drywall with no visible speaker hardware in the finished space.
• Planar-Source Sound Masking — drives the wall surface itself for extremely wide, even coverage.
• SD1-Derived Transducer Technology — uses technology similar to SolidDrive's patented SD1 transducers to transfer acoustic energy to the substrate.
• Rugged Aluminum Enclosure — built with neodymium magnets for concealed, long-term in-wall service.
• Acoustical Uniformity — reduces hot and cold spots compared with point-source speakers.
• Stud-Spacing Bracket Options — installs with the separately sold SD1 mounting bracket, available in widths for common in-wall stud spacing.
• Economical Drywall Masking — a cost-effective approach for spaces that cannot accept ceiling emitters.

Typical Applications

• Open offices with hard-lid ceilings — masking where ceiling emitters cannot be installed.
• Law and financial offices — concealed speech privacy in design-sensitive client areas.
• Healthcare facilities — hidden masking for exam and consultation rooms.
• Conference rooms — invisible masking that preserves architectural finishes.
• Call centers and reception areas — even wall-radiated masking coverage without visible devices.

FAQ

How does the MSK-1 produce masking without a visible speaker?
It is a planar-source transducer that mounts behind the wall and transfers acoustic energy into the drywall substrate, so the wall surface itself radiates the masking signal.

What hardware is required for installation?
The SD1 mounting bracket, sold separately. Bracket widths are available to match common in-wall stud spacing.

When should I choose the MSK-1 over ceiling emitters?
Use it where ceiling devices are impractical or unwanted — hard-lid ceilings, design-sensitive interiors, or retrofit walls — while still needing uniform masking coverage.

How does it compare with the SolidDrive SD1?
The MSK-1 uses technology similar to the patented SD1 transducer but is the economical model purpose-built for drywall sound masking applications.
