d&b Audiotechnik J-INFRA Sub

The d&b Audiotechnik J-INFRA Sub is a specialized subwoofer designed to deliver extremely low frequencies, specifically targeted for large-scale sound reinforcement in live performance venues. As part of d&b’s J-Series, the J-INFRA Sub is engineered to provide powerful infrasound, extending the frequency response of the system down to 27 Hz. This capability allows it to produce deep, impactful bass that enhances the overall audio experience, particularly in large outdoor or indoor arenas.

The D&B Audiotechnik J-INFRA Sub features a unique cardioid design that focuses the bass energy forward while minimizing the rearward sound spread. This design helps in reducing unwanted reflections and vibrations on stage, which is particularly beneficial for clear sound monitoring and overall stage sound management. The subwoofer is equipped with three 21-inch drivers, each housed in a bandpass design, optimizing the unit’s efficiency and performance in delivering precise, high-impact low frequencies.

Moreover, the J-INFRA Sub is designed for seamless integration with other elements of the J-Series, facilitating a coherent and scalable sound system setup. It can be used in different configurations, either ground-stacked or arrayed, depending on the specific requirements of the venue and event. The integration is further enhanced by d&b’s advanced amplification and processing technologies, which ensure that the J-INFRA Sub performs optimally within the system, delivering controlled, powerful bass with exceptional clarity.
