The J12 is a 3-way design housing 2 x 12" LF drivers, one hornloaded 10" MF driver and two 1.4" exit HF compression drivers with 3" voicecoils mounted to a dedicated wave-shaping 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. Due to the dipolar arrangement of the neodymium LF drivers the exceptional 120° horizontal constant directivity dispersion control is nominally maintained down to 250 Hz. The J12 is acoustically and mechanically compatible to the J8 loudspeaker.
The J12 can only be driven by the d&b D12 dual channel amplifier configured for the J12. More detailed information on specific loudspeaker setups with the D12 amplifier is available either in the relevant loudspeaker or D12 manual.
It can be used in columns of purely J12 loudspeakers or combined with J8s and / or with J-SUBs. 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.
