KEF R3 Bookshelf Speakers

R3 redefines standmount performance. No surprise, as it shares the same drivers as the range-topping R11. A true three-way speaker, the 165mm (6.5 in.) bass driver pushes bass performance to new extremes. The 125mm (5 in.) midrange driver and 25mm (1 in.) aluminium dome tweeter creates a Uni-Q array that defies the expectations from the most compact main speaker in the range.
