Description

The J8 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 waveshaping device. The mechanical and acoustical design enables flown vertical columns of up to 24 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 80° horizontal constant directivity dispersion control is nominally 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. The J8 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 NLT4F/M, EP5 or NL8 connectors wired in parallel are also mounted at the rear.

Amplifiers

The d&b D80 and 30D amplifiers are recommended to drive the J8. The 2-Way active J8 requires two channels of the D80.
