d&b audiotechnik J-Series J8 3-Way Line Array Loudspeaker 2×12″ 

ลำโพงแบบแขวนไลน์อาเรย์ d&b audiotechnik J-Series J8 Large format 3-way line array loudspeaker, ขนาดดอกลำโพง 2 x 12″ driver / 1 x 10″ driver, 2 x 1.4″ exit compression driver, passive crossover network, ทนกำลังขับ LF (RMS/peak 10 ms) 500/2000 W, MHF (RMS/peak 10 ms) 200/800 W, impedance 6 Ω (LF) / 12 Ω (MHF)

The d&b audiotechnik 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.

Features:

  • Large format 3-way line array loudspeaker
  • Components 2 x 12″ driver / 1 x 10″ driver 2 x 1.4″ exit compression driver
  • Passive crossover network
  • Power handling capacity LF (RMS/peak 10 ms) 500/2000 W
  • Power handling capacity MHF (RMS/peak 10 ms) 200/800 W
  • Dispersion angle (horizontal) 80°
  • Impedance 6 Ω (LF) / 12 Ω (MHF)
  • Max SPL 145 dB

Amplifiers recommended:

The d&b audiotechnik loudspeaker range is designed exclusively for operation with d&b amplifiers. These provide power as well as comprehensive control and protection functions tailored to achieve the performance, reliability and longevity associated with the d&b System approach. 

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