Perfectly assembled for rich, spacious sound reproduction, this B&H Kit includes two Adam Professional Audio A4V active 4" nearfield studio monitors and one 8", 160W RMS subwoofer, both equipped with advanced room calibration and control features that any professional audio engineer will appreciate. With rotatable HPS waveguides on the tweeters, the studio monitors can be easily adjusted in 90° increments (whether vertically or horizontally mounted) for a wide range of dispersion angles, allowing them to handle a greater variety of room shapes and sizes than your typical 4" speakers. The subwoofer even comes with a handy wireless remote control for adjusting crossover frequency and levels. The combined system provides you with a reliable and convenient high-fidelity monitoring setup.
