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 steel and aluminum, 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.
