The IS7 is a 2-way, full range line array cabinet containing 2x ND7-LM-8 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. 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 SpeakonTM 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.
The IS7 is also available in a weatherized version, purpose-built for use in challenging environmental conditions. Weatherized cabinets feature structural steel elements made of a high yield strength stainless alloy that offers 100% corrosion resistance. They also include an additional protective mesh on the inside of the front grill, as well as an interior and exterior coating that provides a water-resistant seal and allows for easy cleaning and removal of dirt, grime, saltwater, or sand. Weatherized enclosures are rated to IP55 while their cable glands are rated to IP68.
