The Adamson IS5c is an ultra-compact, lightweight, passive 2-way coaxial loudspeaker with a 100° conical dispersion pattern, designed to deliver linear, high-resolution audio throughout its intended bandwidth. It features a 1.4-inch dome compression driver coaxially combined with a 5-inch low-frequency transducer. The enclosure is constructed from marine-grade birch plywood, aircraft-grade aluminum, and steel and includes two Speakon™ NL4 connectors and a 2-point barrier strip. A plate-and-screw rigging system is integrated into the top and bottom of the enclosure, with available accessories providing flexible deployment options. The IS5c can be used as a fill loudspeaker to supplement larger systems or as a standalone solution for smaller applications, including performing arts centers, conference rooms, nightclubs, restaurants, and houses of worship.
