The Bogen SPT15A Reentrant Horn Loudspeaker provides clear voice reproduction and versatile positioning for paging, talkback, and security applications in workplaces, schools, parking lots, warehouses, and other locations. When connected to a 25V or 70V amplifier (sold separately), it produces 15W of power, 121 dB of sound pressure, and a frequency response of 275 Hz to 14 kHz. The impedance and power taps can be adjusted using a seven-position rotary selector protected by a plastic cover that also serves as cable strain relief.
