Smart use of innovative KEF technology means that with Reference 1 you don’t need a big cabinet to enjoy expansive, high-performance sound.
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, large scale sound stage. Uni-Q’s inherently wide, even dispersion also makes it the perfect rear channel speaker in a serious home theatre system.
