Cora
Dual 8, Medium throw, full range line array component


Cora is a lightweight, medium throw, full range line array cabinet. Designed for small to medium size venues, they are easy to rig using Ohm’s Cora flying array frame. The same hardware can be used for both ground-stacking on TRS-118/218 or flown.

With a dispersion of 100° x 12° and an SPL of 143 dB (peak), or in a concert array of 8 boxes SPL of 158 dB (peak), this compact cabinet delivers all this performance despite only weighing 21.7 kg each. Frequency response is an impressive 75 Hz to 21 kHz. Dual Speakon connectors are mounted onto a tough, cast aluminium connection plate which makes daisy-chaining easy.

Key Features:

  • Advanced active dispersion gives 100° x 16° coverage
  • Easy ground-stacking of up to 6 cabinets per frame
  • Unique port design gives excellent dynamics without side-lobing

Technology:

2 way dynamic line array cabinet incorporating a phase-plug controlled waveguide. Housing 2 x 8” proprietary Ohm drivers, internally and externally ventilated double sided high temperature voice coil, 2 x 4” planar wave drivers mounted to a 100° x °12 waveguide integrated LF & HF drivers for a fully coherent phase response. Homogeneous radiating behaviour and linear response from 200 Hz. External active crossovers control the cabinet giving active phase optimization for perfectly controlled dispersion. different multi-laminated wood, eco friendly scratch resistant polyurea paint. Integrated Flying hardware for hanging or ground stacking. Ergonomic butterfly carry handles and recessed Ohm logo.
