The design goal of the QR series has always been to offer the most advanced technology in a perfectly finished and proportioned high-end package. The sound is big, bold and dynamic, yet subtle and detailed when required and an excellent solution for all types of music. The fascia plate is machined from a single piece of Aerospace Grade Aluminium. It has been precision machined, glass blasted, brushed and then anodized in an attractive Tungsten Titanium Grey. It features a rose gold-plated dispersion mesh, which works as an S-Stop filter. This new Audiovector drive unit has the ability to work like a perfect piston over several octaves of the frequency band without the distortion normally found in aluminium/diamond drive units. This means music sounds warm, precise and detailed, yet dynamic and musical.
