Lowell ES-52T 5.25″ Coaxial Ceiling Speaker with Transformer, Backbox & Grille – 70V Commercial Speaker

The Lowell ES-52T 5-1/4″ coaxial in-ceiling speaker delivers clear speech intelligibility and full-range music performance for commercial distributed audio systems. Designed for paging, background music (BGM), and general signaling applications, this self-contained ceiling speaker system includes a coaxial driver, integrated multi-tap transformer, steel back-can enclosure, grille, and mounting hardware for a complete installation solution.

The 5-1/4″ coaxial loudspeaker features a high-frequency Mylar tweeter with acoustic lens, providing crisp high-frequency response and balanced sound reproduction typically associated with premium coaxial speakers. The speaker’s wide dispersion pattern helps provide even coverage throughout the listening area, which can reduce the number of speakers required in distributed sound systems.

The integrated 16-Watt multi-tap transformer supports 25V, 70V, and 100V distributed speaker systems, with selectable power taps and an 8Ω transformer bypass for low-impedance applications. Tap selection is conveniently located behind the grille.

The painted steel back-can enclosure is ported and tuned for improved low-frequency response while providing proper acoustic loading for the driver. The enclosure includes mounting dogs for secure installation in ceiling or wall surfaces.

Installation is simplified with included C-ring mounting ring, support rails, paint shield, and installation template. The press-fit grille with scrim provides a clean architectural appearance, while the included pull tool allows easy grille removal when needed.

With its compact design, wide sound coverage, and integrated backbox construction, the Lowell ES-52T is an excellent choice for retail stores, offices, schools, healthcare facilities, houses of worship, and commercial paging systems.
