Quad 22L Floorstanding Speakers
In true Quad tradition, the L-series dynamic loudspeakers offer levels of detail, neutrality and stereo imaging beyond anything else in their category. Following in the footsteps of their famous ESL brethren, all L-series models set new standards of performance at their prices. A wide frequency response and incredibly accurate drivers produce a sound-stage so vivid and coherent you can visualise each and every sound in three dimensional space. Build-quality is, as you would expect, superb. Each cabinet is made from reinforced 18mm MDF, with a choice of four real wood veneers. Each cabinet then has seven coats of piano lacquer applied, with each coat drying for a full 24 hours before being cut and polished ready for the next coat. High quality gold-plated bi-wire terminals and oxygen free internal wiring ensure excellent signal transmission.
