The KEF R100 is a masterpiece in miniaturisation. Fast, clean and agile, with a low-end performance you would expect from a speaker double its size or with a dedicated LF driver, the R100 has a brilliantly designed full range Uni-Q driver array that makes the smallest R Series bookshelf speaker an astonishing performer.
