This is the 50th anniversary model of the LS50 mini monitor loudspeakers from KEF. 

The Ultimate Studio Experience

With a innovative design that tips its hats to the BBC monitors of the 70s, they are already one of the most recognised speakers around, with a beautiful high gloss finish and a dead centre rose gold Uni-Q driver they are not a speaker you will forget quickly.

A sound usually only available on larger speakers, these compact minimonitors will do nothing but impress & offers a multi-dimensional soundstage usually unavailable from such a compact design & will hardly miss a beat even when driven hard.

Although a lot different in looks the design principles have been taken from the flagship KEF blade speakers. From the driver technolog, baffle design & internal damping these can all be followed back to the blades.

Compact in proportions and yet offering full bodied, stereo sound with 3 dimwensional sound staging, the LS50 is a 2-way design featuring a 130mm Uni-Q bass/ midrange driver with a 25mm dome tweeter located in the centre of the Uni-Q unit. A wide frequency range of 47Hz - 45kHz enables the LS50 to captivate the listener on anystyle of music. 100W power handling with a sensitivity of 85dB/W yields a truly enjoyable and accomplished mini loudspeaker. Piano black finish.

 The LS50 not only won What Hifi's 'Best Standmount' in its price range, but also won their Readers' Award. 

EISA said,

‘…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.’

What Hi-Fi said

We’re impressed by the speaker’s seamless integration, as we are by the way it sets up a huge stereo image populated by securely focused sounds…most importantly these speakers are fun to listen to. Product of the year 2012
