AtlasIED C803A 8-Inch Coaxial Speaker – 16W, 8 Ohm

The AtlasIED C803A is a professional 8-inch, 16-watt coaxial loudspeaker designed for high-quality paging, background music, and distributed audio applications. Featuring a two-way speaker configuration with an integrated crossover network, the C803A provides clear speech reproduction and extended frequency response for commercial, industrial, and institutional sound systems.

Unlike traditional single-cone commercial speakers, the C803A combines an 8-inch low-frequency driver with a 3-inch high-frequency driver, providing improved reproduction of both voice and music.

With a 70Hz–15.5kHz frequency response, 95dB average sensitivity, and 120° dispersion, the C803A delivers broad sound coverage suitable for offices, retail stores, educational facilities, restaurants, and other commercial environments.

The speaker operates at 8 ohms and is designed for use with compatible low-impedance amplifiers. It can also be incorporated into appropriately designed distributed audio systems using a separately selected matching transformer.

Its compatibility with a variety of AtlasIED baffles and enclosures provides flexibility for different installation requirements.

Two-Way Coaxial Speaker Design

The AtlasIED C803A features a two-way coaxial configuration that combines low-frequency and high-frequency reproduction in a single speaker assembly.

The design incorporates:

• 8-inch low-frequency driver for voice and music reproduction
• 3-inch high-frequency driver for enhanced upper-frequency detail
• Built-in crossover network to direct audio frequencies to the appropriate driver

The coaxial configuration allows both drivers to operate within a compact assembly, making it suitable for commercial installations where space and mounting flexibility are important.

This design provides a wider frequency response than many conventional single-cone paging speakers.

Post-Mounted Tweeter Construction

The C803A incorporates a post-mounted high-frequency driver designed to provide additional structural support while maintaining a professional appearance.

The low-frequency driver features a 10-ounce ceramic magnet, while the high-frequency driver uses a 2.35-ounce ceramic magnet.

These components contribute to the speaker's performance across its operating frequency range.

The integrated crossover network helps coordinate the two drivers for balanced sound reproduction.

Extended 70Hz–15.5kHz Frequency Response

The AtlasIED C803A provides a frequency response of 70Hz to 15.5kHz, making it suitable for commercial audio systems requiring both speech intelligibility and music reproduction.

The two-way coaxial configuration helps reproduce a broader range of audio frequencies than basic paging-only loudspeakers.

With 98dB peak sensitivity and 95dB average sensitivity, the speaker provides efficient sound reproduction when connected to a compatible amplifier.

These characteristics make the C803A a practical option for commercial background music systems, general paging, and other applications where audio quality is important.

Wide 120° Sound Dispersion

The C803A features a 120° dispersion pattern, providing broad audio coverage throughout the listening area.

Wide dispersion is beneficial in commercial installations where multiple speakers are used to provide consistent sound levels across a room.

Depending on ceiling height, room acoustics, and system requirements, the C803A can be incorporated into distributed speaker layouts designed for uniform coverage.

Proper speaker spacing and placement should be determined according to the installation.

16-Watt, 8-Ohm Speaker Operation

The AtlasIED C803A is rated for 16 watts and features an 8-ohm nominal impedance.

This model is designed for use with compatible low-impedance audio amplifiers.

Unlike the AtlasIED C5AT72 and C10AT72, the C803A does not include a factory-installed 25V/70V line-matching transformer.

For constant-voltage distributed audio installations, a compatible external transformer must be selected separately.

This distinction is important when choosing speakers for an existing commercial audio system.

Compatible with AtlasIED Baffles and Enclosures

The AtlasIED C803A is designed to accommodate a wide selection of compatible AtlasIED speaker baffles and enclosures.

This allows installers to choose mounting components based on the installation's appearance, ceiling construction, and acoustic requirements.

AtlasIED identifies an optimum sealed enclosure volume of 0.36 cubic feet for this speaker.

Selecting an appropriate enclosure can help support the intended acoustic performance while providing a professional installation.

Baffles, enclosures, and mounting accessories should be selected separately unless specifically included in the product offering.

Designed for Commercial and Institutional Audio
