d&b Audiotechnik J-INFRA Package

The d&b audiotechnik J-INFRA is an ultra-low frequency subwoofer designed to complement the d&b J-Series and other large-format sound systems, providing profound sub-bass extension and impactful low-end performance. Ideal for large-scale events, concerts, and festivals, the J-INFRA enhances the listening experience by delivering extremely deep frequencies that are both powerful and clear. It is engineered for high SPL (sound pressure level) output, ensuring that it meets the rigorous demands of professional audio environments.

The J-INFRA package features a unique design that houses three 21-inch long-excursion drivers in a cardioid arrangement. This configuration allows for controlled low-frequency dispersion, reducing unwanted rear output and minimizing stage noise. The cardioid setup effectively projects the sound forward while maintaining a significant reduction in the sound emitted to the rear of the subwoofer, which is especially beneficial in environments where stage feedback and interference need to be minimized. The deep, controlled bass response extends to frequencies as low as 27 Hz, giving audiences an immersive audio experience with rich sub-bass content.

Constructed with robust marine plywood and coated with a weather-resistant finish, the J-INFRA subwoofer is built for durability and reliable performance in challenging conditions, including outdoor events. The enclosure is designed for stacking and seamless integration with other J-Series components or larger d&b systems, allowing sound engineers to build scalable setups that cater to specific venue requirements. The subwoofer also features recessed handles and sturdy fittings, facilitating transport and installation in both touring and fixed installations.

This J-INFRA package is driven by d&b audiotechnik’s powerful amplifiers, such as the D80 and D20, which provide tailored presets for optimal performance. These amplifiers offer advanced processing features that enhance the control and sound quality of the subwoofer, including real-time monitoring and remote management capabilities. The J-INFRA’s efficiency and synergy with d&b’s amplification ensure that it delivers precise, high-impact low frequencies with minimal distortion, even at high output levels.
