The IS7 is a 2-way, full range line array cabinet containing 2x ND7-LM8 Low-Mid drivers (2x 8 Ω) and an NH3-16 1.4” exit compression driver (16 Ω). 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.
The cabinet construction uses marine grade birch plywood as well as aircraft grade aluminum and steel, and is equipped with two Speakon™ NL4 connectors, or barrier strips available upon request. A plate and screw rigging system is recessed in the interior of the rear rigging fins for easy assembly.
The IS7 is suited to a wide variety of applications. Its full range capability (80 Hz) at reasonable levels qualifies for applications where no extensive sub energy is required. Increased vertical coverage (12.5°) enables the IS7 to cover small to mid-size venues with reasonable speaker quantity. Target applications include performing arts centers, live performance venues, sports venues, conference centers and houses of worship.
