Behringer EUROLIVE B1200D 12" Active 500W Subwoofer

The Behringer EUROLIVE B1200D 12" Active 500W Subwoofer is designed for professional live sound reinforcement applications. The unit features a 12" long excursion woofer powered by an energy efficient Class-D 500W amplifier. Built-in thermal and clip limiters protect the speaker and amplifier from overloading. Externally, the box features a steel grill to protect the cone and ergonomic handles for easy transport. It includes a pole socket for mounting speakers with commercial spacer poles.

For I/O, the subwoofer features two balanced XLR inputs, two balanced XLR outputs, and two XLR Thru jacks for connecting to additional speakers. The back panel includes a tunable and switchable +6 dB bass boost knob between 40 and 90 Hz, a phase button for inverting the polarity of the signal, a 70 to 150 Hz high frequency cut knob, and a volume control.

The high pass filter does not affect the XLR Thru circuit. A set of three LED indicator lights show power to the subwoofer, the presence of a signal, and when the limiter is engaged.
