Speaker is based on a 2-way passive design with a nominal impedance of 16ohms. It contains a 1-inch diaphragm compression driver coaxially-loaded by a low-mid frequency transducer mounted in a bass-reflex tuned enclosure. The cabinet is made of first grade Baltic birch plywood to ensure maximum acoustical and mechanical integrity. A 3/8-inch insert for a microphone stand and two M6 inserts for the ETR5 flying bracket are integrated into the cabinet.
