Lowell ES-52T 70V 5.25-Inch In-Ceiling Speakers

The ES-52T is a high-performance 5.25" coaxial ceiling speaker system engineered for clear voice reproduction and full-range music in commercial environments. Ideal for offices, schools, retail spaces, restaurants, and public facilities, it combines premium audio quality with installation efficiency and code compliance.

Equipped with a 5.25" coaxial driver and Mylar tweeter, the ES-52T delivers crisp high-frequency response and a wide 165° conical dispersion pattern, minimizing the number of speakers needed for even coverage. The built-in 16W transformer includes taps for 25V, 70V, and 100V distributed systems, plus an 8-ohm bypass option for direct connection. A selector switch is conveniently located behind the white grille.

The durable 20-gauge steel enclosure is ported for enhanced bass response and comes pre-mounted to the driver for quick installation. Built-in mounting dogs, a seismic restraint ring, and a low-profile UV-rated plastic baffle ensure safety and versatility across various ceiling types. The fine-mesh press-fit steel grille, paint shield, C-ring, and support rails complete the assembly, making the ES-52T a reliable and flexible choice for professional-grade ceiling audio systems.
