The AtlasIED Atlas+Fyne FS-4D-W is a 4-inch active surface mount loudspeaker combining IsoFlare™ point-source transducer technology, Dante® and AES67 network audio, onboard DSP, and PoE+/PoE++ amplification in a single integrated commercial loudspeaker.

Designed for networked AV and installed sound systems, the FS-4D-W receives audio, power, and control over a single CAT cable, reducing the amount of infrastructure required compared with conventional loudspeaker systems using separate speaker wiring, amplifier channels, and control connections.

An integrated two-channel Class-D amplifier powers the FS-4D-W and provides a secondary 8Ω amplifier output for connection to a compatible passive Atlas+Fyne loudspeaker. This allows a network-connected active loudspeaker to support an additional passive speaker while maintaining centralized configuration and monitoring.

With an IP55-rated, UV-inhibited ABS enclosure, wide 115° conical coverage, network monitoring, and flexible mounting options, the FS-4D-W is designed for commercial environments ranging from corporate and education facilities to hospitality, retail, transportation, houses of worship, and entertainment venues.

IsoFlare Point-Source Technology

The FS-4D-W incorporates IsoFlare point-source transducer technology to provide consistent coverage and coherent sound reproduction from a compact surface-mount enclosure.

The loudspeaker provides a 115° conical nominal coverage pattern, making it suitable for distributed applications where broad and consistent coverage is required.

Its specified frequency performance is:

• 63 Hz–30 kHz frequency range (-10 dB)
• 83 Hz–22 kHz frequency response (±3 dB)
• 115° conical nominal coverage
• 6.1 dB directivity index

Dante and AES67 Network Audio

Built-in Dante network audio allows the FS-4D-W to receive digital audio over standard Ethernet infrastructure.

The loudspeaker also supports AES67, providing additional interoperability for compatible networked audio systems.

Integration with Dante Domain Manager provides additional management capabilities for larger Dante network deployments.

PoE+ and PoE++ Powered Operation

The FS-4D-W supports both PoE+ and PoE++, allowing compatible network infrastructure to supply operating power directly over the Ethernet connection.

A single CAT cable can therefore carry:

• Digital audio
• Power
• Control
• Monitoring data

This can simplify cabling and equipment requirements in larger networked commercial audio installations.

Integrated DSP and Class-D Amplification

The FS-4D-W incorporates onboard DSP and a two-channel Class-D amplifier, reducing the need for separate external amplification and signal processing.

Network-based configuration and monitoring provide control over individual loudspeakers as well as larger multi-zone systems.

Secondary 8Ω Amplifier Output

One of the most important features of the FS-4D-W is its secondary amplifier output, which can power a compatible passive 8Ω Atlas+Fyne loudspeaker.

Available secondary-channel power depends on the PoE power source:

Supported secondary speaker impedance: 8Ω

I would definitely keep this table. It's useful technical information and helps explain that available secondary-speaker power changes depending on the PoE source.

AtlasIED Discover Software Integration

The FS-4D-W integrates with AtlasIED Discover software for network configuration, control, and telemetry.

Network functionality includes:

• Device configuration
• System control
• Status monitoring
• Individual and multi-zone monitoring
• Visual device locator
• Audible device locator
• System supervision

The visual and audible locator functions can be particularly useful when identifying individual loudspeakers in larger networked installations.

AtlasIED FS-4D-W Specifications

Designed for Indoor and Protected Outdoor Commercial Audio

The FS-4D-W features an IP55-rated enclosure manufactured from high-impact ABS with UV inhibitor.

Its weather-treated multi-fiber cone, ferrofluid-cooled titanium high-frequency driver, and durable enclosure construction make it suitable for commercial installations requiring greater environmental protection than a conventional indoor loudspeaker.

I would use wording like this rather than simply calling it an “outdoor speaker.” IP55 tells the customer exactly what environmental rating they're getting without us overstating it.

Typical Applications

• Corporate offices and boardrooms
• Airports
• Convention centers
• Hotels
• Casinos
• Houses of worship
• Retail stores and shopping centers
• Museums
• Lounges and bars
• Sports and fitness facilities
• Performing arts centers
• Educational facilities
• Courtrooms
• Transportation facilities
• Multi-zone foreground music
• Networked paging systems

Why Choose the AtlasIED FS-4D-W?

The FS-4D-W combines the loudspeaker, amplifier, DSP, network audio interface, power delivery, and monitoring functions into a single surface-mount device.

Its Dante/AES67 connectivity and PoE+/PoE++ operation can reduce the amount of separate audio infrastructure required, while the secondary amplifier channel provides the ability to power a compatible passive 8Ω loudspeaker.

For larger installations, network-based configuration and monitoring provide centralized visibility and control over individual speakers and multi-zone systems.

Need a More Compact Dante Loudspeaker?

Need a larger Dante loudspeaker? See the AtlasIED Atlas+Fyne FS-6D-W 6-Inch Dante PoE Active Surface Mount Loudspeaker for a larger 6-inch option with 100° conical coverage and extended low-frequency response.
