12″ FS Series Arena Horn with 90 x 40 Degree Dispersion

The AtlasIED FS12T-94 is a two-way, full-range horn speaker system engineered for clear voice and music reproduction in applications requiring weather resistance. Its 12-inch low-frequency driver and 1-inch high-frequency driver deliver an 80 Hz to 17.6 kHz frequency response, while 90° horizontal by 40° vertical dispersion defines its coverage pattern. With selectable 400, 200, 100, and 50-watt power taps plus a 4-ohm bypass, the FS12T-94 supports multiple system configurations.

Ideal Use Cases

This model is suited to arena sound systems and other multipurpose installations that need full-range voice and music reproduction. Its IP45 environmental rating addresses applications where weather resistance is required. The 90° horizontal coverage pattern can serve areas requiring broad horizontal dispersion, while the 40° vertical pattern provides a more focused vertical coverage area.

The combination of voice and music capability makes the FS12T-94 appropriate when one speaker system must reproduce both spoken announcements and program material. Its specified 128.5 dB maximum SPL and 102.5 dB sensitivity provide concrete performance references for system designers evaluating output requirements.

Why Choose This Model

The FS12T-94 combines a two-way driver arrangement, full-range response, defined directional coverage, and multiple power settings in one horn speaker system. The 12-inch LF driver handles the lower portion of its stated frequency range, while the 1-inch HF driver supports high-frequency reproduction. Together, they cover frequencies from 80 Hz through 17.6 kHz.

Selectable 400, 200, 100, and 50-watt taps give installers several power choices. A 4-ohm bypass is also available for compatible low-impedance system configurations. This selection allows the same model to be considered across installations with different power and connection requirements without changing its core driver configuration or dispersion pattern.

Installation and Integration

The enclosure measures 18.5 inches wide by 19.56 inches high by 18.5 inches deep. Metric dimensions are 46.9 cm wide by 49.78 cm high by 46.9 cm deep. At 48 pounds, or 21.77 kilograms, its size and weight should be considered when planning placement and supporting hardware.

System integration can be based on one of the four listed power taps or the 4-ohm bypass. The selected connection should correspond to the intended amplifier and system design. The 90° horizontal by 40° vertical dispersion specification also provides a defined basis for determining speaker orientation and coverage during layout planning.

The listed color is Pantone 423 C, corresponding to RAL 7045. This reference can be used when coordinating the speaker with surrounding finishes or other installed equipment.

Performance Highlights

Sensitivity is rated at 102.5 dB SPL, and maximum output is specified at 128.5 dB SPL. The stated frequency response of 80 Hz to 17.6 kHz supports both voice and music reproduction within the system’s published operating range. Its two-way architecture separates the driver complement into a 12-inch LF section and a 1-inch HF section.

The 90° by 40° pattern distinguishes horizontal and vertical dispersion rather than using a conical coverage specification. This makes the intended coverage geometry explicit for applications where sound must be distributed across a wider horizontal area with narrower vertical dispersion.

What Makes It Different

The FS12T-94 brings together arena-oriented horn coverage, two-way full-range performance, weather resistance, and flexible power selection. Its combination of a 12-inch low-frequency driver and 1-inch high-frequency driver differentiates it from a single-driver paging horn, while the published 80 Hz to 17.6 kHz response documents its broader voice-and-music role.

The IP45 rating, four selectable wattage taps, 4-ohm bypass, and precisely stated 90° horizontal by 40° vertical pattern provide clear criteria for comparing this model with other speaker options. A 60-month warranty from the date of purchase is also included in the supplied specifications.

Final Assessment

The AtlasIED FS12T-94 is a focused choice for weather-resistant arena and multipurpose sound applications requiring both voice and music reproduction. Its 128.5 dB maximum SPL, 102.5 dB sensitivity, two-way driver system, selectable power taps, and 4-ohm bypass give system designers a detailed performance and integration profile. The 90° by 40° dispersion pattern makes it especially relevant where wide horizontal and narrower vertical coverage are required.
