"Thanks to revolutionary Class-D amplifier technology and internal switch mode power supplies, EUROLIVE B615D loudspeaker provides a much better power-to-weight ratio than competing active speakers. Due to their high-efficiency design, EUROLIVE B615D active loudspeaker cranks out 1500 of the cleanest, punchiest audio Watts Behringer have ever packed into a compact loudspeaker system. The integrated sound processor provides total system control for dependable protection of the LF/HF transducers and thanks to the built-in active high-pass filter, you can run them full out without the slightest hint of distortion. In addition, it features an Ultra-Low Noise (ULN) Mic/Line input with Level control and dedicated 2-band EQ (bass/treble) for easy control.One of the coolest thing about this active loudspeaker is the lack of back-breaking racks of amps, crossovers and EQs that are often required to make passive speaker systems sound almost as good. But that comes with a trade-off-that extra weight is transferred to the loudspeaker, making it difficult for a single user to heave all that mass onto the top of a speaker stand.
