PRA 10

The test winner: Experience top sound in the entry-level class with the newly developed PRA cone technology! The rib-stiffened, paper-glass fiber cone is a real highlight and another ETON milestone in cone development. It is particularly light and also particularly rigid - both basic requirements for a good loudspeaker. Thanks to the rib stiffening, maximum torsional rigidity has been achieved. This ensures ultra-dynamic and powerful bass reproduction, extremely precise and to the point. The PRA series impresses with its warm, full-bodied sound character, rich vocals and incredible spatial depth!
