D&B Audiotechnik J-Subs (Package of 18)

The d&b audiotechnik J-Sub is a high-performance subwoofer designed to provide deep, powerful low-frequency support in large-scale sound reinforcement applications. As part of the d&b J-Series, it is engineered to complement the J-Series line arrays, including the J8 and J12, delivering seamless low-end extension for concerts, festivals, theaters, and large venues. The J-Sub is known for its combination of high output, precision, and clarity, making it a reliable choice for professional sound engineers who need consistent and powerful bass reproduction.

At the heart of the d&b audiotechnik J-Sub is a trio of high-efficiency drivers. It features two forward-facing 18-inch long-excursion drivers and a single 12-inch rear-facing driver, arranged in a cardioid configuration. This design helps control the subwoofer’s dispersion, significantly reducing unwanted low-frequency energy behind the system while maintaining tight, focused bass in front. This cardioid arrangement allows the J-Sub to achieve a balanced low-end response even in acoustically challenging environments, such as large indoor arenas or outdoor spaces where minimizing sound spill is crucial.

The J-Sub operates within a frequency range of 32 Hz to 100 Hz, delivering deep bass tones with exceptional clarity and control. It has a maximum SPL of 139 dB, making it capable of handling high sound pressure levels without distortion or degradation of sound quality. The subwoofer is driven by d&b’s D-Series amplifiers, such as the D12 or D80, which provide DSP-based processing for precise tuning and system optimization. The combination of advanced driver technology, cardioid design, and intelligent amplification ensures that the J-Sub performs consistently, even at high volumes, providing audiences with clear and immersive low-end sound.

In terms of design, the J-Sub is built to withstand the demands of touring and live events. Its robust plywood cabinet is covered in a durable, weather-resistant finish, ensuring that it can handle the rigors of constant use, whether on the road or in permanent installations. The subwoofer is also designed for easy setup and transport, featuring integrated rigging hardware that allows it to be flown or stacked with other J-Series speakers. This flexibility makes it suitable for a wide range of configurations, from ground-stacked arrays to flown subwoofer clusters, depending on the specific needs of the venue or event.
