Atlas Sound FAP8CXT – 8" Coaxial In-Ceiling Speaker 60W 70/100V Transformer

Product Overview

The Atlas Sound FAP8CXT is a premium 8-inch coaxial in-ceiling speaker engineered specifically for high-ceiling commercial audio environments where standard wide-dispersion speakers fall short. Featuring a 1-inch exit compression driver paired with a conical wave-guide horn, the FAP8CXT delivers 90-degree controlled dispersion at the 2kHz octave band, maintaining even coverage and minimizing the SPL drop-off at pattern edges in spaces with ceilings above 12 feet. The factory-mounted 60-watt, 70.7V/100V low-saturation transformer and ported galvanized steel enclosure make this speaker a complete, install-ready solution for distributed audio systems in commercial paging, background music, and public address applications.

Product Description

The FAP8CXT ships pre-assembled to an optimally tuned and ported deep-drawn galvanized steel enclosure with an internal volume of 937 cubic inches, providing extended low-frequency response that conventional shallow backcan ceiling speakers cannot achieve. The 90-degree conical dispersion pattern is a key design parameter for high-ceiling use: speakers with dispersion angles exceeding 90 degrees will produce more than 6dB of level variation from coverage center to edge, causing unacceptable intelligibility inconsistency in large spaces. This speaker holds coverage uniformity within that threshold. The high-frequency section uses a 1-inch exit compression driver coupled to a specially designed conical wave-guide horn, producing high efficiency and accurate treble reproduction suitable for both speech intelligibility and background music quality. Average sensitivity is rated at 92dB, enabling long-distance coverage from lower amplifier power. A front-mounted tap selector switch provides access to power settings from 1.9 to 60 watts at 70.7V, plus an 8-ohm direct bypass, allowing system tuning adjustments without removing the speaker from the ceiling. The unique “trap door” input section supports through-conduit runs with either rigid or flexible conduit, an important feature for commercial construction projects where conduit routing is required. The speaker is C-ring and V-rail tile bridge mounting hardware compatible, and is safety listed to UL 1480 for fire-alarm-rated installations.

Key Features

• 1" Exit Compression High-Frequency Driver — Coupled to a conical wave-guide horn for high output efficiency and accurate high-frequency reproduction in demanding spaces.
• 90-Degree Conical Dispersion (2kHz Octave Band) — Provides even, predictable coverage in high-ceiling environments without the comb filtering caused by over-radiating speakers.
• Optimally Tuned Ported Enclosure — 937 cubic-inch deep-drawn galvanized steel enclosure extends low-frequency response to 60Hz for full-range audio quality.
• 60-Watt 70.7V/100V Low-Saturation Transformer — Factory-installed for distributed audio systems; supports 70V and 100V line architectures.
• Front-Mounted Tap Selector Switch — Power taps from 1.9W to 60W selectable from the front without removing the speaker from the ceiling tile.
• 8-Ohm Bypass Setting — Allows direct coupling to a low-impedance amplifier without the transformer in the signal path.
• "Trap Door" Input Section — Enables through-conduit runs with rigid or flexible conduit for compliant commercial construction installations.
• C-Ring/V-Rail Tile Bridge Mounting Hardware Included — Compatible with standard suspended ceiling grid systems for straightforward installation.
• Press-Fit Grille — Tool-free grille attachment integrates cleanly with contemporary ceiling aesthetics.
• UL 1480 Safety Listed — Meets fire-alarm audio system installation requirements for commercial and institutional buildings.
• 92dB Average Sensitivity — Higher efficiency reduces amplifier load requirements across large distributed speaker runs.

Frequently Asked Questions

Q: Why is 90-degree dispersion important for high-ceiling installations?

A: Speakers with dispersion wider than 90 degrees produce more than 6dB of level drop at the coverage edge in high-ceiling applications. This creates audible loudness inconsistency across a room. The FAP8CXT’s 90-degree pattern holds even coverage and avoids comb filtering from multiple wide-radiating speakers overlapping.

Q: Can the FAP8CXT be used on both 70V and 100V systems?

A: Yes. The built-in transformer supports both 70.7V and 100V distributed audio systems, making it compatible with either standard used in commercial installations.

Q: Can the power tap be adjusted after installation?

A: Yes. The front-mounted tap selector switch is accessible from below the ceiling tile without removing the speaker, allowing level adjustments during or after commissioning.

Q: Does the FAP8CXT support direct low-impedance amplifier connection?

A: Yes. The tap selector switch includes an 8-ohm bypass setting that removes the transformer from the signal path for direct connection to a standard low-impedance amplifier output.

Q: Is conduit routing supported?

A: Yes. The “trap door” input section allows rigid or flexible conduit to pass through the enclosure, meeting commercial construction requirements where open wire runs are not permitted.

Q: Is the FAP8CXT fire-alarm rated?

A: The speaker is safety listed to UL 1480, which covers speakers used in fire alarm and emergency communication systems in commercial buildings.

Q: What ceiling grid hardware is compatible?

A: The FAP8CXT includes C-ring and V-rail tile bridge mounting hardware compatible with standard suspended T-bar ceiling grid systems.
