Atlas Sound PM8GD-B – 8" 2-Way Pendant Mount Speaker 70V/100V (Black)

Product Overview

The Atlas Sound PM8GD-B is an 8" 2-way high-efficiency pendant mount loudspeaker in black, designed for commercial installations where open ceilings or exposed structural elements prevent standard in-ceiling mounting. Using the GD87 coaxial driver with a 16-watt 70V transformer, this 70-volt hanging ceiling speaker delivers high-efficiency performance (96 dB sensitivity at 1W/1m) with 105° coverage in the 2kHz octave band. Long-tail applications include open-ceiling pendant speakers for paging in industrial spaces, high-efficiency 70-volt pendant speakers for gyms and warehouse environments, and black pendant mount speakers for commercial spaces with dark exposed ceilings.

Product Description

The PM8GD-B uses the AtlasIED GD series coaxial driver (GD87), a proven high-efficiency driver that provides familiar response characteristics for integrators working across multiple projects. The 70V transformer provides taps at 1, 2, 4, 8, and 16 watts plus an 8Ω direct input via a concealed terminal block. The extreme high efficiency rating of 96 dB (1W/1m) allows systems designers to use lower transformer tap settings and accommodate more loudspeakers per amplifier channel in high-speaker-count installations, reducing overall system cost. Coverage is 105° (-6dB) in the 2kHz octave band, making this speaker suitable for spaces with higher ceilings requiring wider dispersion from a single point. The PM8GD-B ships with 3 meters of 2mm cable and mounting hardware, and is compatible with standard 3/4" ceiling fan hardware for straightforward field installation. IPX3 splash-resistance rated. Frequency response runs from 70Hz to 15kHz. The PM8GD-B (black finish) and PM8GD-WH (white finish) are identical in performance. Overall diameter is 12 1/4". A 60-month warranty applies.

Key Features

• 8" GD87 Coaxial Driver — Proven high-efficiency driver delivers 96 dB sensitivity (1W/1m) for maximum coverage per watt of amplifier power.
• 105° Coverage Pattern — Wide dispersion (-6dB points at 2kHz octave band) provides broad, even coverage in open-ceiling spaces.
• 16-Watt 70V Transformer — Selectable taps at 1, 2, 4, 8, and 16 watts plus 8Ω direct input via concealed terminal block.
• High Efficiency (96 dB @ 1W/1m) — Allows lower tap settings and more speakers per amplifier channel, reducing installation cost at scale.
• IPX3 Splash Resistance — Protected against water spray from any direction; suitable for covered outdoor or semi-exposed indoor environments.
• Pendant Mount Design — Ideal for open ceilings, industrial environments, and high-bay spaces where surface or in-ceiling mounting is not practical.
• 3m Cable & Hardware Included — Ships with mounting hardware and 3 meters of 2mm cable for straightforward installation.
• Standard Ceiling Fan Hardware Compatible — Fits standard 3/4" ceiling fan mounting hardware already present on many installation sites.
• Black Finish — Coordinates with black structure, ductwork, and exposed ceiling elements in industrial and modern commercial interiors.

Typical Applications

• Commercial meeting space
• Multi-purpose room

Frequently Asked Questions

Q: What is the difference between the PM8GD-B and PM8GD-WH?

A: The two models are identical in performance. The PM8GD-B has a black finish and the PM8GD-WH has a white finish. Choose the finish that matches the ceiling structure or aesthetic of the installation.

Q: What mounting hardware is required?

A: The PM8GD-B includes 3 meters of 2mm cable and mounting hardware. It is compatible with standard 3/4" ceiling fan hardware, and the canopy attaches to a 4" octagon electrical box (provided by others).

Q: Can this speaker be used in an outdoor or covered venue?

A: The IPX3 rating provides protection against water spray from any angle, making the PM8GD-B suitable for covered outdoor spaces and semi-exposed environments. It is not rated for direct rain exposure.

Q: How does the high 96 dB sensitivity reduce installation costs?

A: Higher sensitivity produces more acoustic output per watt, allowing the use of lower transformer tap settings. This means more PM8GD-B speakers can be placed on a single amplifier channel, reducing the amplifier count and wiring in large speaker-count projects.

Q: What amplifier types does the PM8GD-B work with?

A: The PM8GD-B connects to any standard 70.7V or 8Ω amplifier output. It is compatible with AtlasIED PA series amplifiers and other commercial constant-voltage amplifiers.

Q: What warranty applies?

A: AtlasIED provides a 60-month (5-year) warranty from the date of purchase.

Q: Is the PM8GD-B suitable for paging-only applications?

A: Yes. The PM8GD-B is designed with paging functionality as a primary use case. Its frequency response (70Hz–15kHz) and high sensitivity make it effective for speech intelligibility and paging announcements.
