d&b Audiotechnik J-Infra Subs

The d&b Audiotechnik J-Infra Subs is a high-performance subwoofer designed to deliver extended low-frequency reinforcement for large-scale sound reinforcement systems. This cardioid subwoofer is specifically engineered to complement the d&b J-Series loudspeakers, providing powerful, precise, and deep bass reproduction down to 27 Hz. It is a critical component for live sound applications requiring exceptional low-end clarity and impact in expansive venues such as stadiums, arenas, and outdoor festivals.

The J-Infra features three robust 21-inch neodymium drivers, arranged in a unique design to maximize low-frequency energy while minimizing rearward sound emissions. This cardioid setup significantly reduces bass spill behind the array, improving stage monitoring conditions and reducing interference with other audio elements. The drivers are housed in a rugged, tour-ready cabinet constructed to withstand the rigors of frequent transport and deployment.

This subwoofer is powered and managed by d&b’s state-of-the-art amplifiers, such as the D20 or D80, which provide the necessary output and precision processing. The integrated DSP capabilities of these amplifiers ensure optimized performance through customizable crossover settings, equalization, and delay adjustments. The J-Infra is also compatible with d&b’s ArrayProcessing technology, allowing for highly tailored sound coverage and consistent bass performance across the entire audience area.

Deploying the J-Infra is straightforward, thanks to its innovative rigging and stacking options. It can be flown in arrays with other J-Series loudspeakers or ground-stacked for added flexibility in various venue configurations. This versatility makes it an essential tool for sound designers and engineers working on high-demand productions.

In summary, the d&b Audiotechnik J-Infra subwoofer stands out as a pinnacle of low-frequency sound reinforcement. Its combination of power, precision, and innovative design ensures unparalleled bass performance, making it a go-to solution for delivering immersive audio experiences in the most demanding live sound environments.
