It offers a frequency response range of 45 Hz to 150 Hz with a ±3 dB tolerance, suitable for enhancing bass in medium-sized rooms. The subwoofer supports both low-level (50 mV sensitivity, 10 kΩ impedance) and high-level (1 V sensitivity, 200 kΩ impedance) inputs, allowing compatibility with various audio sources. It features a continuously variable low-pass crossover filter adjustable from 50 Hz to 150 Hz and a volume control for user customization. The enclosure is a tuned port design, measuring 11.5 inches (29.2 cm) in width, height, and depth, and weighs approximately 11.8 kg. The BU-1 also includes an auto-sensing power circuit that turns the subwoofer on when audio signals are detected. Its compact size and versatile input options make it suitable for integration into home audio systems to provide deep, clear bass reproduction.
