Atlas Sound FAP42TC – 4" Coaxial Shallow-Mount 70V Ceiling Speaker Pair

Product Overview

The Atlas Sound FAP42TC is a 4-inch coaxial in-ceiling speaker from the Strategy II series, featuring a 16-watt 70V/100V transformer and a shallow low-profile mounting depth, sold in pairs in a white finish. As a shallow-mount 4-inch coaxial 70V ceiling speaker for constrained ceiling cavities, the FAP42TC is the solution for installations where plenum depth or structural obstructions prevent the use of a standard-depth ported enclosure speaker. Long-tail use cases include shallow ceiling cavity commercial AV speaker, low-profile 70V in-ceiling speaker for retrofit installations, and Strategy II coaxial ceiling speaker for space-limited commercial build-outs.

Product Description

The FAP42TC shares the same coaxial driver, transformer tap configuration, and dispersion characteristics as the standard FAP42T series, but is packaged in a shallow-depth enclosure specifically designed for ceiling cavities where a full-depth ported enclosure will not fit. This makes it a practical choice for retrofit installations in existing commercial buildings, low-profile slab ceilings, or new construction projects with structural constraints. The coaxial driver design places the tweeter at the center axis of the woofer, producing coincident-source 130-degree wide dispersion for uniform coverage across the listening plane. The internal 70.7V/100V transformer provides multi-tap operation at 1, 2, 4, 8, and 16 watts on the 70V line, plus a transformer bypass for direct 8-ohm operation. A front-mounted tap selector switch is accessible after installation without removing the speaker from the ceiling. The detachable Phoenix-style connector allows pre-wiring and daisy-chain connections to additional FAP-series speakers. Installation hardware is included for drop-tile and sheetrock ceiling applications. The white paintable grille blends with standard commercial ceiling tile. The FAP42TC carries UL 1480 safety listing and is sold as a pair per order at $309.98.

Key Features

• Shallow Low-Profile Mounting Depth — Compact enclosure depth accommodates ceiling cavities where standard-depth ported enclosures cannot be installed, enabling use in retrofit and constrained-depth new construction applications.
• Coaxial Driver with 130-Degree Dispersion — Coincident tweeter and woofer design provides wide, consistent coverage across conference tables, seating areas, and open commercial floor plans.
• 16-Watt 70V/100V Transformer with Bypass — Multi-tap transformer at 1W, 2W, 4W, 8W, and 16W for 70V/100V distributed systems, plus an 8-ohm bypass for direct amplifier connection.
• Front-Mounted Tap Selector — Accessible from the front face of the installed speaker to adjust power tap settings without ceiling access above the tile.
• 4-Pole Phoenix Detachable Connector — Pre-wiring-ready connector with daisy-chain capability for easy connection of multiple FAP-series speakers on a shared circuit run.
• Included Mounting Hardware — C-ring/V-rail tile bridge and dog-leg hardware for standard drop-tile and sheetrock ceiling installation.
• White Paintable Grille — Press-fit white grille integrates with standard acoustic tile and can be painted to match custom ceiling finishes.
• UL 1480 Listed, Sold in Pairs — Safety-listed to UL 1480; must be ordered in multiples of two with a 60-month warranty.

Technical Specifications

Frequently Asked Questions

Q: How does the FAP42TC differ from the FAP42T?

A: The FAP42TC has a shallow low-profile mounting depth, making it suitable for ceiling cavities where a standard-depth ported enclosure cannot fit. The driver, transformer taps, and dispersion specifications are equivalent to the FAP42T series.

Q: What is the minimum ceiling cavity depth required for the FAP42TC?

A: The FAP42TC is specifically designed to reduce depth requirements for constrained ceiling cavities. Refer to the AtlasIED dimensional drawings for the exact cutout and cavity depth specifications before installation planning.

Q: Does the FAP42TC support both 70V and 100V operation?

A: Yes. The internal transformer supports both 70.7V and 100V distributed audio line voltages with the same tap settings.

Q: Can the FAP42TC be used with a low-impedance amplifier?

A: Yes. The tap selector includes an 8-ohm transformer bypass for direct low-impedance amplifier connection without 70V distribution.

Q: Is the grille available in colors other than white?

A: The FAP42TC ships with a white grille that is paintable to match custom ceiling colors. A black-finish version is available as the FAP42T-B for standard-depth ported enclosure requirements.
