Description
Need clear, powerful paging that cuts through the roar of machinery, wind, or crowds? The Bogen SPT30A delivers exactly that. This compact 30-watt reentrant horn loudspeaker gives you loud, intelligible sound for one-way announcements or two-way talk-back systems.
Built tough with all-metal construction and a weatherproof design, it handles indoor factories, outdoor loading docks, warehouses, schools, construction sites, and transportation terminals without missing a beat. The built-in 25V/70V transformer with easy rotary taps makes it simple to match your existing paging amplifier. Tilt-and-swivel base lets you aim the sound right where you need it.
Real-world performance: In a busy warehouse test, the SPT30A at 15W tap produced clear voice paging from over 75 feet away even with forklift noise in the background. For higher-noise spots (85-95 dB ambient), we recommend the full 30W tap.
Setup tip from our team: Mount these at 15-20 feet high and angle them slightly downward toward the listening area. Use the optional TCSPT1 terminal cover if you're running conduit-it keeps connections protected and code-compliant. Pair it with a Bogen TPU-series amplifier for best results.
