Behringer B1520DSP.
Good conditions
powerful sound
Designed to suit almost every environment, the B1520DSP Eurolive Digital Processor-Controlled 600W RMS 15" PA Speaker with Integrated Mixer by Behringer can rock a live concert or inspire a congregation. How do they do it? The secret is in the bi-amped Rms600 watt engine which drives a high-efficiency 15" woofer and a 1.75" titanium driver. A built-in mixer lets you control everything without any additional equipment.
What more could you want, except maybe a brain? The B1520DSP provides that as well. The powerful 24-bit DSP controls the crossover, the dual compressor, phase and time corrections, and noise gate. In addition, an intelligent dynamic EQ corrects and adjusts so you get perfect audio at any sound level..
