Atlas Sound C10AT25 – 8-Inch Dual Cone In-Ceiling Speaker with 25V 5W Transformer, Pair (Black)

Product Overview

The Atlas Sound C10AT25 is an 8-inch dual cone in-ceiling loudspeaker with a factory-installed LT-25 25V 5-watt line-matching transformer, sold as a pair in black. Featuring a curvilinear treated paper cone, 10 oz ceramic magnet, and a 1-inch copper voice coil, the C10AT25 delivers 97dB sensitivity and 105-degree dispersion for general-purpose commercial audio distribution on 25V systems. It mounts to a wide selection of AtlasIED round and square baffles for flexible installation in commercial, industrial, and institutional environments.

Product Description

The C10AT25 is designed for 25-volt distributed audio systems in multi-speaker commercial installations where smaller tap selections provide precise load balancing across many zones. It shares the same proven C10A driver platform as the C10AT72, offering identical acoustic performance with a 25V-only transformer variant rated at 5 watts maximum. The dual cone design achieves a 105-degree wide dispersion pattern and a frequency response of 100Hz to 10kHz for balanced voice and music reproduction in rooms of various sizes. The 10 oz ceramic magnet provides a stable magnetic circuit, and the curvilinear treated paper cone minimizes harmonic distortion during both speech and music reproduction. The 1-inch copper voice coil on a black anodized aluminum former manages heat effectively during continuous operation, supporting the 25-watt speaker driver's power handling. The factory-installed LT-25 transformer supports power tap settings at 0.5, 1, 2, and 5 watts, giving installers the flexibility to properly load 25V distribution circuits. The black finish suits installations in darker ceiling environments. Compatible with a wide range of AtlasIED round and square baffles and back boxes, the C10AT25 accommodates diverse enclosure options. AtlasIED's HyFi hydrophobic treatment is available as an optional upgrade for installations in high-humidity environments. A 60-month warranty applies from the date of purchase.
