The mocha Bogen Communications SPT30A is a 30W reentrant horn loudspeaker offering intelligible voice reproduction and versatile positioning for paging, talkback, and security applications in work sites, schools, parking lots, warehouses, and more. When connected to a 25V or 70V amplifier (available separately), it delivers a 30W output, a sound pressure level of 125 dB, and a frequency response of 225 Hz to 14 kHz. Impedance and power taps are adjustable via a seven-position rotary selector, which is protected by a plastic cover that also provides cable strain relief.
Its weatherproof, all-metal housing ensures reliable durability indoors and outdoors, and can be precisely tilted and swiveled using the sturdy mounting bracket. Banding slots allow mounting to a beam or pillar, and alternative mounting options are supported via separately available accessories. The screw terminal input connections accommodate quick wiring to your constant-voltage amp. The self-aligning diaphragm is field-replaceable.
