The AtlasIED M2000-LP is a compact, low-profile 70.7V sound masking speaker assembly engineered for commercial installations where ceiling plenum space is limited. Measuring just 2⅝ inches high, this specialized speaker provides an effective way to distribute sound masking signals in shallow ceiling cavities, helping support speech privacy and reduce distracting conversations in offices, healthcare facilities, and other professional environments.
Unlike conventional sound masking speakers that require deeper ceiling spaces, the M2000-LP features a compact square enclosure housing two 2" × 4" paper-cone loudspeakers. This dual-speaker configuration is designed to reproduce sound masking signals while fitting into restricted installation areas.
An integrated 70.7V transformer includes selectable 0.25W, 0.5W, 1W, 2W, and 4W power taps, along with an OFF setting. The front-mounted external tap selector allows installers to adjust individual speaker output during system balancing and commissioning.
The M2000-LP arrives preassembled and includes an input cover with conduit knockouts and strain relief for secure wiring. Its UL 1480 and UL 2043 listings support use in appropriate commercial air-handling and plenum installations.
Important: The AtlasIED M2000-LP is a passive sound masking speaker. A compatible sound masking generator and 70.7V amplifier are required for operation and are sold separately.
Low-Profile Design for Shallow Ceiling Plenums
One of the primary advantages of the AtlasIED M2000-LP is its compact enclosure.
With a height of only 2⅝ inches (67mm), the speaker is designed for locations where conventional sound masking assemblies may be too large.
Its shallow profile makes it particularly useful in commercial buildings with restricted space above suspended ceilings.
The compact enclosure measures:
-
Height: 2⅝" (67mm)
-
Width: 7½" (191mm)
-
Depth: 7" (178mm)
These dimensions allow system designers to incorporate distributed sound masking speakers into smaller ceiling cavities while maintaining the installation flexibility required for commercial applications.
Dual 2" × 4" Loudspeakers for Sound Masking
The AtlasIED M2000-LP features two 2-inch by 4-inch paper-cone loudspeakers mounted within a compact square enclosure.
This configuration is engineered specifically for the reproduction of sound masking signals rather than conventional background music or high-output paging.
When connected to a properly designed sound masking system, the M2000-LP distributes controlled background sound to help reduce speech intelligibility between nearby work areas.
This can be particularly beneficial in open offices, shared workspaces, and administrative areas where conversations may otherwise become distracting.
The M2000-LP's enclosure is designed to support consistent reproduction of the masking signal within the speaker's intended operating range.
Adjustable 70.7V Transformer with External Tap Selector
The M2000-LP includes a high-efficiency 70.7V transformer, allowing multiple loudspeakers to operate as part of a distributed sound masking system.
A front-mounted selector switch provides the following settings:
-
0.25 watts
-
0.5 watts
-
1 watt
-
2 watts
-
4 watts
-
OFF
These adjustable taps allow installers to set individual speaker levels based on room conditions, ceiling construction, and system design requirements.
The external selector also simplifies commissioning by making power adjustments accessible without opening the enclosure.
Plenum-Rated Construction and Convenient Wiring
The AtlasIED M2000-LP is designed for installation in appropriate commercial plenum and air-handling spaces.
Its input cover incorporates knockouts and strain relief, providing installation options for compatible rigid or flexible conduit.
A Romex-style clamp input with color-coded leads helps simplify electrical connections.
The enclosure also accommodates through-connections where required by the system wiring layout.
The M2000-LP is listed to UL 1480 and UL 2043, making it suitable for installations requiring these safety standards when installed in accordance with applicable codes.
Preassembled for Efficient Commercial Installation
The AtlasIED M2000-LP is supplied as a preassembled sound masking speaker assembly.
Its compact construction reduces the amount of on-site assembly required, while the accessible transformer tap selector helps simplify final system adjustments.
At just 3.3 lbs (1.49 kg), the unit is relatively lightweight for installation in restricted ceiling spaces.
These features make it a practical choice for commercial projects requiring multiple sound masking speakers in shallow plenums.

Recommended Applications
Open-Plan Offices: Supports sound masking systems designed to reduce distracting conversations and improve speech privacy.
Small Ceiling Plenums: Ideal for commercial installations with limited space above suspended ceilings.
Healthcare Administration Areas: Provides masking audio for suitable offices and administrative workspaces.
Corporate Workspaces: Supports distributed sound masking in shared offices, conference areas, and professional environments.

Important Installation Requirements
The AtlasIED M2000-LP requires a compatible sound masking generator and 70.7V amplifier to operate.
The speaker does not generate masking audio or include an integrated power amplifier.
For effective results, speaker placement, transformer tap settings, masking signal levels, and overall system calibration should be determined by the requirements of the sound masking installation.
Need a Sound Masking Speaker for a Larger Plenum?
For installations with more available ceiling clearance, consider the AtlasIED M1000-W Sound Masking Speaker Assembly. Its 8-inch dual-cone loudspeaker, 734-cubic-inch enclosure, and flexible EZ hang mounting system provide another option for commercial sound masking installations.
