It's a high-resolution, active 2-way reference studio monitor that is perfect for nearfield monitoring applications: from small mixing environments to multi-channel surround setups. Despite its small size, the TRUTH B2030A can achieve a peak output level in excess of 113 dB SPL. Powered by separate 75- and 35-Watt built-in amplifiers with an active crossover, these monitors provide ultra-linear frequency response from 50 Hz to 21 kHz. A long-throw 6 3/4 in. woofer with a special polypropylene diaphragm delivers smooth, deep bass, while an extremely high-resolution HF driver delivers highs that are crystal-clear and full of detail. The unique BEHRINGER wave guide and the extremely low-distortion crossover network produce an absolutely linear phase response with excellent sound dispersion and stereo imaging. The B2030A is equipped with servo balanced inputs on XLR and 1/4 in. TRS connectors to handle a variety of audio sources. Thanks to its compact size and magnetic shielding, the TRUTH B2130A can be placed near video monitors, computer displays or digital audio workstations. The B2030As are delivered along with individual measurement diagrams. Audio InputsXLR connector: servo-balanced input1/4 in.
