The IS5c is an ultra-compact, light-weight, passive 2-way coaxial loudspeaker, with a 100° conical dispersion pattern. Designed to produce linear, high-resolution audio throughout its intended bandwidth, the enclosure contains a 1.4” dome compression driver coaxially combined with a 5” low frequency transducer.
The cabinet construction uses marine grade birch plywood as well as aircraft grade aluminum and steel, and is equipped with two Speakon™ NL4 connectors, as well as a 2-point barrier strip. A plate and screw rigging system is placed on top and bottom of the enclosure, with available accessories allowing the enclosure to be deployed seamlessly in a variety of applications.
The IS5c is suited to supplement larger systems as a fill cabinet, or to handle smaller applications on its own. Target applications include performing arts centers, conference rooms, night clubs, restaurants, and houses of worship.
