Description
The Essence of the Signature Line. The QRB embodies every core value of our design philosophy. Sculpted from 2cm-thick slabs of pure quartz, its elegant form is as enduring as it is acoustically inert. A foundation that allows music to emerge with breathtaking purity.
A beryllium tweeter, free of coloration and constraint, soars with effortless detail, while a meticulously voiced crossover crafted from hand-selected, exotic components ensures seamless harmony throughout the spectrum.
