To casual viewers
the LS50 will look like a minimalist, single-driver loudspeaker but in reality
it’s more sophisticated. In fact, this single driver is one of KEF’s famous
two-way Uni-Q units with its tweeter mounted at the acoustic centre of the
mid/woofer. This latest iteration, coloured rose gold, features a cone formed
of a special magnesium/aluminium alloy and benefits from a longer ‘throw’ to
improve bass performance. The cabinet is not only beautifully finished but is
sturdily constructed with constrained layer damping between its walls, internal
cross-brace and front baffle. As promised, the LS50 delivers a remarkably big
sound with vivid imaging and a tremendous bass weight that belies its compact
dimensions. Shut your eyes and you’ll believe you are listening to a far bigger
loudspeaker.
