8″ Coaxial Loudspeaker 100W

Ideal Use Cases

The AtlasIED FA138 is an 8-inch coaxial in-ceiling loudspeaker designed for paging and background music. Its published 100-watt rating at 8 ohms makes it suitable for systems built around an 8-ohm speaker load. The in-ceiling design addresses projects where loudspeakers will be integrated overhead, while the specified 110-degree dispersion provides a concrete coverage figure for system planning. These characteristics make the FA138 a practical candidate when both spoken announcements and background program material are part of the audio requirements.

Why Choose This Model

The FA138 brings its principal performance specifications together in one clearly defined design: an 8-inch coaxial speaker, a 100-watt power rating at 8 ohms, a frequency response of 75 Hz to 20 kHz, and 110-degree dispersion. Published sensitivity is 89.5 dB average and 93 dB peak, allowing designers to evaluate the loudspeaker using both stated measurements. It is also safety listed to UL 1480 and UL 2043. A warranty period of 60 months from the date of purchase adds a clearly documented term for long-term ownership planning.

Installation and Integration

The loudspeaker has a stated diameter of 8 1/4 inches, or 20.955 cm, and a depth of 3 5/8 inches, or 9.144 cm. These measurements should be considered when evaluating available ceiling area and installation depth. The published shipping weight is 5.20 pounds, or 2.36 kilograms; because this is specifically identified as shipping weight, it should not be treated as an installed product weight. The supplied data does not state the required ceiling cutout, mounting hardware, connector type, grille details, or included accessories, so those items should be confirmed separately before installation. The 8-ohm specification should also be matched to the amplifier and overall system design.

Performance Highlights

A frequency response extending from 75 Hz to 20 kHz gives the FA138 a documented operating range for evaluating both paging and background-music requirements. Its sensitivity specifications distinguish between an 89.5 dB average value and a 93 dB peak value, preserving the two measurements supplied for the product. The 110-degree dispersion specification provides another useful parameter for determining speaker placement and spacing. Power handling is stated as 100 watts at 8 ohms, without an additional continuous, program, or peak classification in the supplied information.

What Makes It Different

The defining combination is an 8-inch coaxial format, in-ceiling installation, 100-watt rating, 8-ohm operation, and suitability for both paging and background music. Rather than leaving coverage and sensitivity unspecified, the product data supplies a 110-degree dispersion figure along with average and peak sensitivity values. UL 1480 and UL 2043 safety listings further distinguish the documented specification set. The source information does not identify driver materials, crossover details, enclosure construction, transformer options, weather resistance, or paintable components, so no claims are made for those characteristics.

Final Assessment

The AtlasIED FA138 is a focused choice for an in-ceiling audio system requiring an 8-inch coaxial loudspeaker rated at 100 watts and 8 ohms. Its 75 Hz to 20 kHz frequency response, 89.5 dB average and 93 dB peak sensitivity, 110-degree dispersion, and UL 1480 and UL 2043 listings provide concrete criteria for system comparison. With a 60-month warranty from the purchase date, the FA138 offers a documented specification package for paging and background-music applications.
