**PACK OF 2** 4″ Premium Ceiling Speaker (Blind Mount)

This pack contains two AtlasIED FC-4T IsoFlare™ ceiling speakers. Each FC-4T is a two-way, full-range loudspeaker designed for blind-mount ceiling installation. The four-inch model combines wide bandwidth, high sensitivity, and superior fidelity with a clean ceiling-oriented format. Its published coverage, power-handling, impedance, and transformer-tap specifications provide concrete information for planning a two-speaker installation.

Ideal Use Cases

This two-pack is intended for projects requiring a pair of four-inch ceiling loudspeakers with the same acoustic and installation specifications. A 100° nominal coverage angle at -6dB supports designs where broad coverage is required from each installed position. The blind-mount configuration is appropriate when the FC-4T installation format is specified.

The available transformer taps and Low Z operation accommodate systems requiring more than one operating approach. The pair format is particularly useful when two ceiling locations need the same FC-4T model, frequency performance, coverage pattern, and power-handling capability.

Why Choose This Model

The FC-4T combines a two-way, full-range configuration with AtlasIED IsoFlare™ technology. Its specified frequency range extends from 62Hz to 30kHz at -10dB, while the stated frequency response is 80Hz to 22kHz at +/-3dB. These separate ratings clearly identify both the model’s overall bandwidth and its more tightly defined response window.

System sensitivity is rated at 88dB for 1W measured at 1 meter. Directivity is documented with a 100° nominal coverage angle at -6dB and a directivity index of 4.7. These published values give system designers specific sensitivity and dispersion information instead of relying only on general descriptions of performance.

Installation and Integration

The FC-4T uses a blind-mount ceiling design. A rotary selector switch provides transformer-tap selection listed as 30W, 15W, and 7.5W, with the source specification also identifying 3.8W at 70V and Low Z operation. This selection supports integration into systems designed around the available transformer settings or a low-impedance connection.

Nominal impedance is 8 ohms, and the recommended amplifier power is 120W at 8 ohms. Because this listing is for two speakers, the same installation format and operating selections are available at both intended speaker positions. Amplifier choice, transformer setting, and Low Z use can be evaluated directly against the published FC-4T ratings.

Performance Highlights

Average power handling is rated at 60W, with 120W programme and 240W peak ratings. These three figures distinguish continuous average capability from programme and short-duration peak handling. The rated maximum SPL is 106dB average. With the maximum transformer tap, the listed average maximum SPL is 104dB.

The acoustic specifications include a 62Hz to 30kHz frequency range, an 80Hz to 22kHz frequency response, 88dB system sensitivity, and 100° nominal coverage. Together, these values define the FC-4T’s bandwidth, output reference, and coverage behavior. The four-inch IsoFlare™ design is described as offering wide bandwidth, high sensitivity, and superior fidelity for exceptional coverage and aesthetics.

What Makes It Different

The FC-4T brings together a four-inch format, two-way full-range operation, blind mounting, and selectable transformer or Low Z operation in one ceiling loudspeaker model. Its published specifications extend beyond basic wattage by including sensitivity, two frequency measurements, nominal coverage, directivity index, impedance, recommended amplifier power, and maximum SPL.

This listing also provides two FC-4T speakers rather than a single unit. Both use the same model specification, making the package suitable when a consistent AtlasIED ceiling-speaker platform is required in two locations. The product carries a warranty period of 60 months from the date of purchase.

Final Assessment

The AtlasIED FC-4T two-pack is a strong match for a design that specifically calls for two four-inch, two-way full-range ceiling speakers with blind-mount installation. Its 100° coverage, 88dB sensitivity, 60W average power handling, 8-ohm nominal impedance, rotary transformer-tap selection, and Low Z capability provide a detailed basis for system planning. The documented 62Hz to 30kHz frequency range and five-year warranty complete a clearly specified ceiling-loudspeaker package.
