The d&b J-Series continues the established d&b audiotechnik approach to the design and manufacture of loudspeaker systems. It is intended for use in large-scale sound reinforcement applications, providing incredibly quick and easily configurable array solutions even in the most arduous situations. Control of dispersion behaviour is a particular fixation at d&b, as is keeping the size and weight of systems to an absolute minimum; these are both areas in which the J-Series excels. It also embodies the d&b holistic approach to sound reinforcement solutions: integrating loudspeakers, electronics, mechanical deployment assemblies, remote control functions, transport solutions and set up design tools for precise calculation of array performance.

J12 loudspeaker
J12 loudspeaker

The J12 loudspeaker is designed specifically for use in large-scale sound reinforcement applications. It is a 3-way design housing 2 × 12" LF drivers, one hornloaded 10" MF driver and two 1.4" exit HF compression drivers with 3" voicecoils mounted to a dedicated waveshaping device. The mechanical and acoustical design enables flown vertical columns of up to twenty-four loudspeakers to be suspended using vertical splay angles between them of 0° to 7° with a 1° resolution. The cylindrical wave segments produced couple coherently in the vertical plane. The symmetrical dipolar arrangement of the neodymium LF drivers around the centrally mounted coaxial MF and HF components allows a smooth overlap of the adjacent frequency bands in the crossover design. This results in an exceptional 120° horizontal constant directivity dispersion control nominally being maintained down to 250 Hz. The J12 is acoustically and mechanically compatible with the J8 loudspeaker. It can be used in columns of purely J12 loudspeakers or combined with J8s and /or with J-SUBs. Cabinets are mechanically connected using the rigging links on both sides of the cabinet front, and with a central rigging link on the rear of the loudspeaker. The J12 cabinet is constructed from marine plywood and has an impact and weather protected PCP (Polyurea Cabinet Protection) finish. The front of the loudspeaker cabinet is protected by a rigid metal grill, the side and rear panels incorporate four handles, and two EP5 or NL8 connectors wired in parallel are also mounted at the rear.

The cylindrical wave segments produced couple coherently in the vertical plane. The symmetrical dipolar arrangement of the neodymium LF drivers around the centrally mounted coaxial MF and HF components allows a smooth overlap of the adjacent frequency bands in the crossover design. This results in an exceptional 80° horizontal constant directivity dispersion control nominally being maintained down to 250 Hz. The J8 is acoustically and mechanically compatible with the J12 loudspeaker. It can be used in columns of purely J8 loudspeakers or combined with J12s and/or with J-SUBs.

J Subwoofer
J Subwoofer

The J-SUB is the subwoofer for the J-Series. It is an actively driven 2-way bass-reflex design housing three long excursion neodymium 18" drivers, two drivers face to the front and one driver to the rear. The cardioid dispersion pattern resulting from this approach avoids unwanted energy behind the system that greatly reduces the reverberant field at low frequencies and provides the greatest accuracy of low frequency reproduction. The J subwoofer can be used to supplement J8 and J12 loudspeakers in various combinations, ground stacked or flown, either integrated on top of a J8/J12 array or as a separate column. Cabinets are mechanically connected using the rigging links on both sides of the cabinet front, and with a central rigging link at the rear of the cabinet. The J-SUB cabinet is constructed from marine plywood and has an impact and weather protected PCP (Polyurea Cabinet Protection) finish. The front and rear of the loudspeaker cabinet are protected by a rigid metal grill and the side panels incorporate eight handles. Four 100mm wheels and one EP5 or NL8 connector are mounted at the rear.
