The Atlas Sound ALA5T is a component within a commercial loudspeaker system, specifically a 3-inch full-range driver designed for paging, background music, and voice announcement applications. The product code "LA SYS (5)" indicates it is part of a larger system kit, likely containing five of these drivers along with accompanying transformers, back cans, and grilles for a complete multi-speaker installation. The "6M/125W" specification denotes a key feature: a multi-tap line-matching transformer integrated with the driver. This transformer allows the speaker to be safely and efficiently connected to a constant-voltage amplifier system (typically 70V or 100V), which is the standard for commercial sound installations in offices, retail stores, schools, warehouses, and hospitals. The 125W rating refers to the maximum power the transformer can handle, allowing for flexible power tapping (e.g., 1W, 2W, 4W, 8W, etc.) to balance volume levels across multiple speakers on a single amplifier channel.

The driver itself is a 3-inch cone transducer built for clarity in the vocal range and adequate frequency response for background music. Its compact size and design make it suitable for flush-mounting in drop ceilings (using a compatible back can) or surface-mounting on walls. The "Pass Gray" finish refers to a standard, neutral gray color that blends discreetly into commercial interiors. The integrated line-matching transformer is critical for system design, as it steps down the high voltage from the amplifier to a lower level suitable for the driver and provides impedance matching, enabling dozens of speakers to be wired in parallel on a single amplifier output without overloading it. This simplifies installation and allows for easy zoning and volume adjustment per speaker.

As part of Atlas Sound's commercial audio product line, the ALA5T driver is engineered for reliability, long-term performance, and ease of installation. It is a fundamental building block for architects, consultants, and installers designing distributed audio systems where clear, intelligible sound coverage over a large area is required from a centralized amplifier.
