All the jaw-dropping performance and innovative engineering pioneered for the critically acclaimed LS50 studio monitor, and then some. Reference 1 pairs KEF’s latest 125mm (5 inch) MF/HF Uni-Q driver array with the sensational new 165mm (6.5 inch) alloy cone bass driver to create a compellingly realistic sound stage out of all proportion to its size. Mounted on shelves or stands, Uni-Q’s inherently wide, even dispersion also makes it the perfect rear channel speaker in a home theatre system that effortlessly reveals all the subtleties encoded in modern soundtracks. |
