kef ls50 black edition loudspeakers
The LS50 was inspired by the LS3/5a, a small mini monitor designed and developed by the BBC using KEF drive units for monitoring purposes. This design was licensed out to speaker manufacturers to reproduce domestically available models. The LS50 takes the idea and updates it with KEF's UniQ technology, as well as computer modelling and analysis allowing measurements that just weren't possible back in the 1970s.
This model is the "Black Edition", sporting not only a black cabinet, but also a black mid/bass driver, offering a more inconspicuous, "stealthy" look.
Form follows function.
Packing technology developed during the "no hold's barred" design of the Concept Blade loudspeakers, the KEF LS50 Black Edition speakers are a 'bookshelf' speaker capable of performance far greater than their small proportions would have you believe.
They're equally at home in the living room as part of a high quality, compact hi-fi system for music reproduction as they are in a multi-channel home theatre system, creating the subtle ambiance of a movie soundtrack, as well as accurate sound effects placement thanks to its two-way, wide dispersion UniQ driver array.
Their coincident driver placement and symmetrical dispersion allows the flexibility of using the speaker upright or lying on its side with identical results, ideal for use as high quality satellite speakers for home theatre systems, or spaces where height is limited.
Whilst a conventional loudspeaker cabinet is a nice easy shape to produce and work with, it doesn't necessarily allow the drive units used to perform at their best. This is why the LS50 Black Edition loudspeaker uses a curved front baffle. The forward most point of the speaker is the edge of the roll surround on the mid/bass driver, therefore, the front baffle plays no part in the output of the speaker itself, unlike loudspeakers with a flat front panel. The reflected sound you'll be hearing will be from your room.
But KEF have that covered too. Because of the symmetrical UniQ array, the dispersion of the driver is exactly the same radially through 360 degrees, which again, isn't the case with conventional loudspeakers. This wide, uniform dispersion is far less sensitive to room reflections, allowing you to hear more of the speaker and less of the reflected sound you'd normally hear in your listening room.
The cabinet is heavily braced, with a thick, sound deadening front panel, reducing vibrations reaching the rest of the cabinet. Whilst most KEF loudspeakers are similarly voiced, we feel the resulting sound of the LS50 Black Edition is what you would get from a sub £1,000 KEF Reference, should such a thing be possible.
The KEF LS50 speakers are one of our favourite products at the little audio company, so are permanently available for audition.
