Atlas Sound AP-30T – 30W Dual Re-Entrant Horn Loudspeaker with Transformer

Product Overview

The Atlas Sound AP-30T is a double re-entrant horn loudspeaker delivering 30 watts of continuous power handling across 25V, 70.7V, and 100V distributed audio systems. Designed for commercial paging horn applications in indoor and outdoor environments, the AP-30T provides 108 dB sensitivity and a 300 Hz–12 kHz frequency response for clear voice and tone signaling. Its weather-resistant construction and Omni-Purpose mounting bracket make it a reliable choice for mass notification horn speaker installations in factories, warehouses, parking structures, and campuses.

Product Description

The AP-30T is part of Atlas Sound's AP Series, a line of U.S.-manufactured horn loudspeakers recognized for long-term service reliability in demanding environments. The double re-entrant design produces superior speech intelligibility compared to single-horn projectors, making it effective for both voice paging and electronic tone signaling. Operating across a temperature range of -40°C to 70°C, the AP-30T handles extreme conditions without performance degradation. The multi-tap transformer supports power taps of 2W, 3.75W, 15W, and 30W on the 70.7V line, giving installers precise coverage control in 70V distributed paging systems. The trademarked squared-bell design and grey epoxy finish on metal components provide a professional appearance that blends with commercial architecture. The included Omni-Purpose bracket achieves precise vertical and horizontal positioning with a single adjustment and accommodates conventional surface mounting as well as strap mounting on I-beams and pillars. ABS plastic components complement the metal construction for a balance of durability and weight. Pair the AP-30T with the Atlas TSD-HF11 high-pass filter to protect the driver from low-frequency damage in systems where bass content may be present on the line.
