The compact Genelec 4030C installation speaker is a powerful system ideal for small to mid-sized commercial installations. Genelec 4030C contains drivers, power amplifiers, active crossover filters and protection circuitry. This integrated design makes installations easier and more efficient as separate power amplifiers are not needed. The Minimum Diffraction Enclosure (MDE™) is made of die-cast aluminium and shaped to reduce edge diffraction. The Genelec 4030C features Genelec Intelligent Signal Sensing (ISS™) circuitry which switches the loudspeaker to standby when no audio input is detected (ErP 2013 Directive).
