This loudspeaker is designed specifically for use in large-scale sound reinforcement applications. It is a 3-way design housing two 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 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 mechanical and acoustical design enables vertically-flown 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 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 and the side and rear panels incorporate four handles.

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. It can be driven only by the d&b D12 dual-channel amplifier configured for the J8. More detailed information on specific loudspeaker setups with the D12 amplifier is available either in the relevant loudspeaker or D12 manual.
