Hence, to give a tribute to all of their amazing tech innovations by the launching of the LS50. This was a very special launch from the KEF to appreciate their very 50th year.

The concept of the LS50 was completely influenced by the legendary BBC studio monitor.

The name and model of the studio monitor were LS3/5a.

Along with it, you won’t be able to find any audiophile forum in which you won’t read anything about these spectacular speakers.

Right after the launch of the speakers, they have gained immense popularity from the media and users.

The speaker’s coincident Uni-Q driver turns out to be the specialty of these speakers. In these the tweeter, and woofer project sound from the very same physical point in the space.

Hence, the ultimate design of the speakers seems to be iconic.

The LS3/5a was considered the go-to monitor by the BBC for decades.

As the sound and performance of the speaker were astonishing many speakers built concerning these BBC LS3/5a by the many manufacturers.

Therefore, if at all the KEF was to launch any project based on this legend then the result indeed is going to be a very special speaker.

Though, the product looks very similar to its predecessor. The KEF LS50 is completely redesigned from the inside.

The cabinet design, port, drivers, and crossovers are arranged with the most suitable arrangements to deliver the best quality of sound.

The most marketable change that you can find in these speakers is the use of a new metamaterial that sits behind the uni-q driver unit to absorb the rear radiation of the driver.

The cabinet of the KEF LS50is designed with piled MDF and the front end is designed with a hard resin.

The KEF made a realistic and outstanding job with the finish on the LS50wireless. This not only appears solid but is also beautifully crafted and refined by considering every detail.

Accordingly, the curved baffle of the KEF LS50 provides optimized sound management and also minimizes the edge diffractions. 

The unwanted vibrations and resonances are also suppressed by the very effective bracing and the tightening of the cabinet of the speakers.

During the time of the occasional residual resonances, they are kept separated from the internal and external structure by using the insulation on critical parts.
