About the Sonetto III G2
The Sonus faber Sonetto III G2 is a premium Italian-made passive floorstanding loudspeaker in the second-generation Sonetto collection. Its 2.5-way architecture separates the rear-vented midwoofer section from the down-vented woofer section, while an integrated cast-concrete base improves mechanical stability and supports the downward bass-reflex loading. The cabinet uses Sonus faber’s lute-inspired form and combines wood, leather and concrete elements. It is sold as a stereo pair and is offered in piano gloss black, walnut, and wenge finishes.
