The AtlasIED PM8CX-B is a high-performance 8-inch coaxial pendant loudspeaker designed to deliver clear, intelligible audio in commercial spaces with high ceilings. Featuring the AtlasIED 8CXT60 coaxial compression driver, this suspended speaker combines high sensitivity, controlled sound dispersion, and flexible power options for professional paging, background music, and sound reinforcement applications.
Engineered for mounting heights up to 30 feet, the PM8CX-B features a 90° conical coverage pattern measured in the 2 kHz octave band. This controlled dispersion helps direct sound toward the listening area, improving speech intelligibility and reducing unnecessary sound energy outside the intended coverage zone.
With 70.7V transformer taps at 7.5, 15, 30, and 60 watts, plus an 8-ohm direct input, the PM8CX-B accommodates both distributed commercial audio systems and low-impedance amplifier configurations. Its suspension design makes it especially useful in facilities where traditional flush-mounted ceiling speakers are impractical.
Features and Benefits
High-Efficiency 8-Inch Coaxial Speaker
The PM8CX-B incorporates the AtlasIED 8CXT60 coaxial compression driver, delivering an average sensitivity of approximately 92 dB (1W/1m).
Its coaxial design provides a compact sound source for reproducing speech and music, making it suitable for commercial audio systems where intelligibility and consistent coverage are important.
Designed for High-Ceiling Applications
Unlike conventional in-ceiling loudspeakers, the PM8CX-B is designed to be suspended from overhead structures.
Its pendant-style configuration allows installers to position the speaker appropriately in large, open spaces with ceiling heights reaching 30 feet.
This makes it a practical solution for gymnasiums, warehouses, auditoriums, shopping areas, and other commercial environments with exposed or elevated ceilings.
Controlled 90° Conical Coverage
The PM8CX-B provides a nominal 90° dispersion pattern in the 2 kHz octave band, corresponding to approximately 45° off-axis coverage.
This controlled coverage helps focus sound toward the intended listening area rather than dispersing it unnecessarily throughout the surrounding space.
Proper speaker placement and spacing can help improve speech clarity and achieve more consistent coverage across large areas.
Flexible 70.7V and 8-Ohm Operation
The PM8CX-B supports multiple amplifier and system configurations through its selectable transformer taps and direct low-impedance connection.
Available power options include:
-
7.5W, 15W, 30W, and 60W taps for 70.7V distributed audio systems
-
8-ohm direct input for compatible low-impedance amplifiers
-
150W RMS power rating in 8-ohm operation
These options allow system designers to select the appropriate operating configuration based on available amplifier power, speaker quantity, and desired sound levels.
Wide Frequency Response for Speech and Music
With a specified frequency response of 55 Hz to 15 kHz, the PM8CX-B is designed to reproduce a broad range of audio content.
This makes it suitable for facilities requiring both intelligible voice announcements and music playback through the same loudspeaker system.
Convenient Pendant Mounting
The PM8CX-B includes approximately 3 meters of 2 mm suspension cable and mounting hardware to support installation.
Its mounting arrangement is compatible with standard 3/4-inch ceiling fan hardware, providing installers with additional flexibility when planning suspended loudspeaker installations.
A concealed terminal block helps maintain a clean, professional appearance while providing access for audio connections.

Recommended Applications
Gymnasiums and Indoor Sports Facilities
The controlled coverage pattern and high-output coaxial driver make the PM8CX-B suitable for announcements and sound reinforcement in facilities with elevated ceilings.
Warehouses and Distribution Centers
Pendant mounting allows loudspeakers to be positioned closer to the listening area in large industrial spaces where traditional ceiling speaker installation may not be practical.
Auditoriums and Multipurpose Facilities
The PM8CX-B provides a versatile option for speech reinforcement, paging, and music reproduction in large gathering spaces.
Retail Stores and Shopping Centers
Suitable for commercial audio systems requiring background music and paging coverage across open areas with high ceilings.
Houses of Worship
The combination of coaxial driver performance and controlled dispersion makes the PM8CX-B useful for supplemental sound coverage in worship spaces with elevated or exposed ceilings.
