The IS7 is a 2-way, full range line array cabinet containing 2x ND7-LM8 Low-Mid drivers (2x 8-ohm) and an NH3-16 1.4-inch exit compression driver (16-ohm). The critically optimized waveguide produces a slightly curved wavefront with a nominal dispersion pattern of 100° x 12.5° (H x V). The waveguide’s efficiency allows for increased vertical dispersion without sacrificing high frequency presence in the far field. Patent-pending Controlled Summation Technology further eliminates low-mid lobing normally associated with 2-way line source systems.
