Bookshelf speakers Audiovector QR1

I'm selling used Bookshelf speakers Audiovector qr1 in great working condition. The tweeter features AMT (Air Motion Technology) which isn’t quite a ribbon tweeter, despite its appearance. It is instead a gold leaf membrane. This membrane is pleated, is low mass and the air is squeezed between the pleats. There is a super thin rose gold plated dispersion mesh over this leaf membrane. This mesh acts like a POP filter in a recording studio, removing unwanted sibilance. This thin mesh diaphragm is then mounted in a single piece of Aerospace Grade Aluminium that is “machined, glass blasted, brushed, and then anodized to a Tungsten Titanium Grey colour”. The 15 cm woofer (6 inches in fact) in the QR1 is a piston design and it includes a new sandwich membrane, which “combines the strength of (more) Aerospace Grade Aluminium with the excellent inner damping properties of softer materials. The result is a 3-layer sandwich membrane with no sound of its own and very low distortion”. There is front facing slot reflex port to move the air around the cabinet. The overall idea in the design, says Audiovector is to deliver “non-fatiguing and dynamic listening sessions”. The quoted frequency response for the loudspeaker is 45 Hz – 45 kHz with an impedance quoted at 4 Ohms and sensitivity is claimed 86dB/W/m. The loudspeakers are flawlessly (hand) finished with soft curves in this black gloss version. There are in fact three finishes available, piano black, dark walnut and white silk. The rear of the cabinets have a solid metal finish and the binding posts are solid and very satisfying. Dimensions (H x W x D) – 32.5 x 19 x 23.2cm Collection from Dublin 6. I can ship also.
