d&b J-INFRA (Package of 2)

The d&b audiotechnik J-INFRA is a high-performance subwoofer that is meticulously engineered to deliver deep, powerful low-frequency sound reproduction for the most demanding live sound and large-scale events. Designed as an infra-subwoofer, the J-INFRA extends the low-end range of a sound system down to a remarkable 27 Hz, providing a rich, immersive bass experience that resonates with audiences at festivals, concerts, and large venues. Its capacity to handle extreme low frequencies with precision makes it a key component in achieving high-impact audio for a wide range of musical genres and event types.

At the heart of the J-INFRA are three 21-inch neodymium woofers configured in a unique cardioid arrangement. This design provides exceptional directionality by focusing the low-frequency energy toward the audience while minimizing unwanted bass emissions to the sides and rear. This cardioid pattern not only enhances the audience’s listening experience by reducing muddy, uncontrolled bass but also creates a quieter stage environment, allowing performers and crew to operate without interference from excessive low-end vibrations.

Built for reliability and ease of use, the J-INFRA features a rugged plywood enclosure with an environmentally resistant finish. Its robust construction makes it ideal for both touring applications and permanent installations. The cabinet includes integrated rigging hardware, which facilitates quick and secure setup in flown or ground-stacked configurations. It pairs seamlessly with d&b’s advanced amplifiers, such as the D80, which provide comprehensive control over parameters like crossover points, equalization, and delay settings. This ensures that the J-INFRA integrates perfectly within larger d&b sound systems, making it a versatile choice for sound engineers seeking consistency and precision.

In summary, the d&b audiotechnik J-INFRA is a state-of-the-art subwoofer that combines unmatched low-frequency power, directional control, and durability. Its ability to deliver clean, controlled bass at extremely low frequencies makes it indispensable for creating immersive soundscapes at high-profile events. As part of d&b’s renowned product lineup, the J-INFRA ensures a level of performance and reliability that meets the expectations of world-class audio professionals. Whether in a stadium, arena, or open-air festival, the J-INFRA consistently raises the standard for bass reproduction.
