Finally, great-sounding active loudspeakers that won't break your back or bank account. Thanks to Behringer's revolutionary Class-D amplifier technology and internal switch-mode power supplies, Eurolive D Series loudspeakers provide a much better power-to-weight ratio than competing active speakers. Put simply, you get all the power without the back-breaking weight. And the sound quality of these lightweight loudspeakers exceeds that of the extremely popular Eurolive B212A and B215A systems -- plus they've included two 200-Watt models, the B210D (10") and B208D (8") for less demanding applications. Due to their high-efficiency design, they crank out 550/200 of the cleanest, punchiest audio Watts you've ever heard from a compact loudspeaker system. The integrated sound processor provides total system control, along with dependable protection of the LF and HF transducers, thanks to the built-in active high-pass filter, which virtually eliminate distortion -- even at extreme operating levels. In addition, all four models feature an Ultra-Low Noise (ULN) Mic/Line input with Level control and a dedicated 2-band EQ (bass/treble) for easy control.
