AtlasIED FAP42T-B 4" Coaxial In-Ceiling Speaker – Black

The AtlasIED FAP42T-B is a high-performance 4-inch coaxial in-ceiling speaker designed for clear speech reproduction and high-fidelity background music in commercial audio installations. Featuring a factory-installed 16-watt 70.7V/100V transformer, wide 130° dispersion, and a tuned, ported steel enclosure, the FAP42T-B delivers balanced sound reproduction in a compact ceiling-mounted design.

Part of the AtlasIED Strategy Series II, the FAP42T-B combines a polypropylene cone woofer with a coaxially mounted PEI dome tweeter to provide detailed audio reproduction across its specified 75Hz–20kHz frequency range.

Its wide coverage pattern makes it particularly useful for commercial spaces with lower ceilings, where fewer loudspeakers may be needed to achieve consistent sound distribution.

The FAP42T-B features a black finish, making it an attractive choice for installations with dark ceilings, exposed architectural elements, or spaces where a black speaker grille is preferred.

With a front-accessible transformer tap selector, detachable Phoenix-style connector, and included ceiling mounting hardware, the FAP42T-B offers convenient installation and flexible system integration.

Premium 4-Inch Coaxial Speaker Design

The AtlasIED FAP42T-B incorporates a high-quality 4-inch coaxial loudspeaker designed for both speech intelligibility and music reproduction.

Its two-way design combines a polypropylene cone woofer with a coaxially mounted high-frequency tweeter.

The woofer features a butyl rubber surround, while the PEI dome tweeter reproduces higher frequencies for clear vocals and detailed music playback.

This combination makes the FAP42T-B suitable for commercial environments requiring more than basic paging-only sound reproduction.

Speaker Components

• 4-inch polypropylene cone woofer
• Butyl rubber woofer surround
• 1-inch voice coil
• 10-ounce woofer magnet
• 19mm coaxially mounted PEI dome tweeter
• Integrated 70.7V/100V transformer

The coaxial design provides a compact speaker assembly suitable for distributed ceiling speaker systems.

Wide 130° Dispersion for Low-Ceiling Applications

The FAP42T-B features a 130-degree dispersion pattern designed to provide broad sound coverage.

This wide coverage is particularly useful in rooms with lower ceilings, where a narrower-dispersion loudspeaker may require additional units to cover the listening area.

The FAP42T-B can help installers design efficient distributed speaker layouts for offices, retail spaces, restaurants, and other commercial environments.

Its coverage characteristics make it suitable for both paging and background music systems.

Actual speaker spacing and coverage will depend on ceiling height, room acoustics, and the required listening levels.

Tuned and Ported Steel Enclosure

The AtlasIED FAP42T-B includes an optimally tuned, ported enclosure designed to improve low-frequency performance.

The enclosure is constructed from deep-drawn galvanized steel and provides an internal volume of approximately 285 cubic inches.

This design helps extend the speaker's low-frequency response while maintaining a compact ceiling-mounted configuration.

Unlike speakers that require a separately purchased backbox, the FAP42T-B is supplied as an integrated speaker and enclosure system.

The ported design is particularly useful in commercial background music applications where balanced sound reproduction is important.

70.7V/100V Transformer with Selectable Power Taps

The FAP42T-B features a factory-installed 16-watt 70.7V/100V transformer designed for commercial distributed audio systems.

For 70.7V operation, the speaker provides the following selectable transformer taps:

• 1 watt
• 2 watts
• 4 watts
• 8 watts
• 16 watts

These settings allow installers to adjust individual speaker output levels based on room size, listening requirements, and system design.

Lower transformer taps can be useful in quieter areas, while higher taps provide additional output where needed.

The transformer is designed to minimize insertion loss and preserve low-frequency performance.

Front-Mounted Tap Selector and 8Ω Bypass

The AtlasIED FAP42T-B includes a convenient front-mounted selector switch.

This allows installers to adjust transformer tap settings without removing the speaker assembly from the ceiling.

The selector also includes an 8-ohm transformer bypass setting for direct connection to a compatible low-impedance amplifier.

This provides additional flexibility when integrating the speaker into different audio system configurations.

The manufacturer lists a speaker power rating of 25 watts at 8Ω. However, its installation instructions specify that amplifier output should not exceed 16W RMS per speaker in the 8Ω configuration.

Important: Never use the 8Ω bypass setting when connected to a 70.7V or 100V amplifier output.

Detachable Phoenix-Style Connector

The FAP42T-B features a detachable 4-pole Phoenix-style/Euroblock connector.

This connector allows installers to prepare wiring before installing the speaker assembly.

It also supports convenient connection of additional compatible speakers in distributed audio systems.

Benefits include:

• Convenient pre-wiring
• Detachable terminal connection
• Simplified speaker installation
• Support for through-wiring to additional compatible speakers
• Easier service access

The speaker also includes a dedicated wiring access section designed to accommodate appropriate conduit connections.

All wiring should follow the manufacturer's installation instructions and applicable electrical requirements.

Easy Installation in Drop Tile and Drywall Ceilings

The AtlasIED FAP42T-B is designed for installation in both suspended ceiling tiles and suitable drywall ceilings.

The speaker includes a C-ring/V-rail tile bridge and dog-leg mounting system.

These components help simplify installation while supporting the speaker assembly.

The dog-leg mounting mechanism secures the enclosure in the ceiling opening.

Installation Features

• C-ring/V-rail tile bridge included
• Integrated dog-leg mounting system
• Suitable for supported drop tile installations
• Suitable for supported drywall installations
• Front-accessible transformer tap selector
• Detachable connector for convenient pre-wiring
• Press-fit grille for a finished appearance

The manufacturer specifies a 9-inch ceiling cutout diameter.

Installers should verify ceiling thickness, structural support, and mounting requirements before installation.

Black Press-Fit Grille for Architectural Integration

The FAP42T-B features a black press-fit grille designed to blend into contemporary commercial spaces.

The grille provides a clean finished appearance without visible front-mounted attachment screws.

The black finish is particularly useful for:

• Dark ceiling installations
• Restaurants and hospitality spaces
• Retail environments
• Theaters and presentation rooms
• Contemporary commercial interiors

The press-fit design also allows convenient access to the speaker's front-mounted controls during installation and maintenance.

75Hz–20kHz Frequency Response

The AtlasIED FAP42T-B provides a manufacturer-listed frequency response of 75Hz–20kHz.

Its coaxial driver design and tuned enclosure support clear reproduction of speech and background music.

With an average sensitivity of 88dB, the speaker is designed for efficient performance in commercial audio systems.

For applications requiring additional deep bass, the FAP42T-B can be paired with a compatible subwoofer system.

Compatible with the AtlasIED FAPSUB

For commercial music systems requiring extended low-frequency reproduction, the FAP42T-B can be integrated with the AtlasIED FAPSUB subwoofer system.

The FAPSUB provides additional low-frequency output for applications where full-range ceiling speakers alone may not deliver the desired bass performance.

This combination can be useful in restaurants, retail environments, hospitality spaces, and other commercial background music installations.

The FAPSUB is a separate product and is not included with the FAP42T-B.

UL 1480 Safety Listed

The AtlasIED FAP42T-B is listed to UL 1480, according to the manufacturer's specifications.

This listing is relevant for commercial audio installations requiring safety-listed loudspeaker equipment.

Installers should confirm the applicable building and electrical requirements for each project.

• Commercial paging systems
• Background music installations
• Restaurants and hospitality venues
• Retail stores
• Corporate offices
• Conference rooms
• Educational facilities
• Institutional buildings
• Commercial distributed audio systems
