The BP15DSP Bogen Pro Loudspeakers are portable, 2-way self-powered loudspeakers capable of high sound pressure levels. Their built-in amplifiers and the quality of their transducers offer better performance than any loudspeaker in their range. A specially designed multi angle cabinet enclosure allows these speakers to be positioned for use in a variety of settings. The low frequency selector allows the speakers to be quickly configured for any environment, while the direct microphone input allows easy set up for voice reinforcement applications.
