Great sound and great choice

The PRIMUS audio system shines with lively sound and powerful bass. Thanks to the 2.1 speaker system with integrated 5.25-inch high-performance subwoofer, the PRIMUS not only impresses with quiet tones, but also offers space for big sound. PRIMUS uses both analogue (e.g. wooden body or flow-optimized bass reflex tube) and digital (e.g. digital sound processor) sound technology and creates a sensational sound experience with the best of both worlds. Perfect for rooms up to 25 square meters.

Representative design

The PRIMUS audio system not only impresses with its sound quality, but also with its minimalist design. Typical sonoro. The all-metal front and control knobs, the high-quality, lacquer-finished wooden housing and the automatically dimmable display exude quality. With its slim dimensions and minimalist design, PRIMUS fits in with many furnishing styles and looks good anywhere. Quality that you can not only hear, but also see.
