About the Concertino G4
The Sonus Faber Concertino G4 is the fourth generation of the iconic Concertino series, celebrating 30 years since the original introduction. It features a 2-way vented port design with a 1-inch silk dome tweeter using Sonus Faber's DAD technology and a 5.25-inch paper pulp mid-woofer with an organic basket. The central chassis is crafted from cork, a natural material that limits internal resonances and reduces the need for additional damping inside the cabinet. The side walls are made of solid walnut wood with ribbed surfaces for enhanced rigidity without internal bracing. The cabinet is finished with recycled leather or a plant-based leather alternative. The reflex port is located at the back to avoid front turbulence. The crossover is designed with a phase-coherent philosophy for accurate phase alignment and a defined sound image. The speaker comes with a custom iron stand featuring walnut veneer inserts. The Concertino G4 offers a frequency response of 60 Hz to 25 kHz, sensitivity of 85 dB, nominal impedance of 4 ohms, and recommended amplifier power of 30 to 150 watts. Dimensions without stands are approximately 8.4 x 12.4 x 11.6 inches, and each speaker weighs about 14.5 pounds.
