Atlas Sound FC-4T – 4" IsoFlare Premium Ceiling Speaker Blind Mount

Product Overview

The Atlas Sound FC-4T is a 4-inch premium in-ceiling loudspeaker using IsoFlare point source driver technology, designed for high-fidelity music and speech reinforcement in commercial environments where audio quality and installation aesthetics are equally important. The FC-4T blind-mount ceiling speaker delivers broad, even coverage from a compact 4-inch form factor, with a 30-watt 70V/100V transformer and a magnetically secured edgeless grille for a clean architectural appearance. It is warranted for 60 months and carries a 5-year track record as a benchmark product in the IsoFlare premium ceiling speaker line.

Product Description

The FC-4T is built around AtlasIED's IsoFlare coaxial driver, which aligns the high-frequency and low-frequency sources at a single acoustic point, producing a spherical wavefront that propagates consistently in all directions. This point-source alignment delivers a constant time delay across the entire frequency spectrum, resulting in flat off-axis response that most conventional coaxial drivers cannot achieve. The ferrofluid-cooled titanium tweeter with neodymium magnet system maintains consistent high-frequency performance while the weather-treated multi-fiber cone provides stiffness combined with controlled top-end rolloff for accurate midrange reproduction. The Fluted Surround Technology on the woofer surround eliminates back-reflection energy that causes coloration in standard driver designs. The optimized smooth-transition baffle eliminates sharp edges that produce diffraction artifacts. The full-bandwidth 30-watt 70V/100V transformer has very low insertion loss, preserving fidelity in distributed line applications. High-current premium crossover components—air-core inductors and polypropylene capacitors—maintain phase accuracy. The easy-access tap selector switch allows power tap selection (30W, 15W, 7.5W, and 3.8W at 70V) without tools. The patented toolless high-travel secure-clamp mechanism installs the speaker in the ceiling without fasteners, and the magnetically secured edgeless grille requires no adapters for optional square grille variants. The grille logo is removable and the assembly supports single-step painting. Enhanced voicing presets are accessible via the AtlasIED Atmosphere platform for integrators who require DSP-based tuning adjustments. The FC-4T is designed for boardrooms, corporate spaces, airports, convention centers, hotels, houses of worship, and other venues where foreground music and speech clarity both matter.

Technical Specifications

Frequently Asked Questions

Q: What makes the FC-4T different from a standard coaxial ceiling speaker?

A: The IsoFlare driver aligns the HF and LF sources at the same acoustic point, producing a spherical wavefront and constant time delay across the frequency range. This results in flat off-axis response and accurate imaging that conventional coaxial drivers—which have separate HF and LF acoustic centers—cannot achieve.

Q: Does the FC-4T require a cutout template?

A: Yes. A standard ceiling cutout is required per the specifications. The toolless blind-mount clamp mechanism secures the speaker from the front after installation without access to the ceiling plenum.

Q: What power taps are available on the 70V transformer?

A: The rotary tap selector switch provides 30W, 15W, 7.5W, and 3.8W at 70V, plus a low-impedance (direct 8-ohm) position.

Q: Is the FC-4T compatible with the AtlasIED Atmosphere DSP platform?

A: Yes. Enhanced voicing presets are available via the Atmosphere platform for integrators who require software-based EQ and tuning adjustments.

Q: What is the warranty period?

A: The FC-4T carries a 60-month (5-year) limited warranty.

Q: Can the grille be painted to match the ceiling?

A: Yes. The edgeless grille design supports single-step painting. The logo is removable before painting. Optional black and white grilles are also available.
