The Atlas+Fyne FS-4D is a premium wide-bandwidth 4-inch active surface mount loudspeaker engineered for exceptional fidelity, consistent coverage, and architecturally sensitive environments.
For the first time in a commercial surface speaker, IsoFlare™ point-source technology is combined with the flexibility of the Audinate Dante® digital audio networking platform, integrated DSP, and PoE+ / PoE++ amplification in a single, streamlined solution.
A single CAT cable delivers audio, power, control, and monitoring—simplifying installation while unlocking advanced system configuration, supervision, and calibration capabilities.
Advanced Networked Audio Integration
The FS-4D is fully compatible with Dante and AES67 IP audio streams and supports PoE+ and PoE++ for scalable power options. Integrated amplification eliminates the need for external amplifiers, reducing rack space and wiring complexity.
A secondary amplifier output allows local connection to a passive Atlas+Fyne loudspeaker, expanding coverage without additional network endpoints.
Key network features include:
-
Dante and AES67 compatibility
-
Dante Domain Manager support
-
AtlasIED Discover software for configuration, telemetry, and control
-
Visual and audible device locator
-
Full control and monitoring of individual speakers and multi-zone systems
IsoFlare™ Point-Source Technology
IsoFlare™ represents a new benchmark in point-source loudspeaker design for prestigious commercial installations.
Unlike traditional coaxial or discreet HF/LF designs, IsoFlare™ technology provides:
-
Excellent harmonic alignment between high- and low-frequency sources
-
Natural, highly accurate tonal reproduction
-
Spherical wavefront propagation aligned on all axes
-
Even frequency response across the listening area
-
Constant time alignment throughout the frequency spectrum
-
Exceptional off-axis performance
The result is consistent voicing and measured performance across the entire IsoFlare™ Series—whether ceiling, surface, or pendant mounted.
Built for Commercial Reliability
The FS-4D is designed for applications requiring premium music playback and highly intelligible speech reinforcement in a durable, installer-friendly format.
Construction highlights include:
-
IP55-rated enclosure for indoor/outdoor durability
-
High-impact ABS cabinet with UV inhibitor
-
Ferrofluid-cooled titanium HF driver
-
Neodymium magnet system
-
Weather-treated multi-fiber cone for controlled top-end roll-off and accurate midrange
-
Integrated DSP and dual-channel Class D amplification
Flexible Installation Options
Safe, efficient installation is supported by:
-
Included slip-free yoke mount
-
Optional universal pan-and-tilt bracket
-
Compatibility with third-party VESA® mounting systems
Its minimalistic industrial design makes it ideal for architecturally sensitive spaces.
