Bogen SPT30A Re-entrant Horn Loudspeaker for 25V and 70V Amplifiers, 30W, Textured Mocha Enamel Finish

For dependable voice evacuation, paging and mass notification across industrial and public facilities, the Bogen SPT30A re-entrant horn loudspeaker delivers powerful, intelligible audio where it matters most. This Bogen horn loudspeaker combines a 30W amplifier with a rotary impedance selector so installers can quickly match the unit to 25V or 70V constant-voltage systems without extra transformers. The rugged, all‑metal weatherproof housing stands up to outdoor exposure while the tilt-and-swivel base allows precise aiming for optimal coverage—reducing speaker counts and installation time.

Designed for security, surveillance and monitoring deployments, the SPT30A provides consistent voice clarity for emergency notification, facility-wide paging, and transportation terminals. Its high efficiency and re-entrant horn design make it an excellent choice for one-way paging or two-way talkback systems in warehouses, campuses, and public venues. Upgrade your mass notification and security audio infrastructure with a proven, durable speaker.
