Most Important Features & Specs of KEF LS50

When it comes to performances of bookshelf speakers, the biggest complaint the users have is the bass. But, that is not the case with KEF LS50! These speakers simply excel when it comes to reproducing low-frequency sounds.

The bass is deep and powerful, which is rather surprising considering that the sound is coming from such a small set of speakers. But, the size apparently does not matter. At least in the case of KEF LS50, which are capable of creating bone-shaking bass, which still does not steal the show entirely. Instead, it keeps everything in balance. And that means that the mids and highs also sound perfect. The vocals are incredibly accurate, without absolutely no distortions.

And all of that is achieved through the use of the following features:

  • Uni-Q® driver – KEF engineers worked very hard to come up with a driver that’s gonna create fast and clear sound. And they’ve managed to do it. It’s called Uni-Q and is used in several speakers from KEF’s collection, including LS50. Why this driver is so special is that it’s made of a 25mm tweeter (aluminum dome) that’s placed inside a 13cm mid/bass (magnesium/aluminum–coned).
  • Wave-guard – By looking at these speakers, you could think that there’s a grill covering the front of the tweeter. But, in fact, it’s a waveguide, the purpose of which is not only to make the design of the speakers more exciting, but also to boost the performances at high frequencies.
  • Frequency range of 47Hz – 45 kHz – What this basically means is that it covers almost all the frequencies that the human ear can register. You can play literally any music and these speakers will be able to reproduce it flawlessly.
  • DMC front panel – Take a closer look at the speakers and you will notice that the front panel is curved. And that’s not done by accident. The curved design is actually deliberate as it gives the speakers’ performances a boost. And the same goes for the material of which the front is made. DMC a.k.a. Dough Moulding Compound might be the ideal material for high-performance speakers as not only does it boost audio quality, it also makes them more rugged.
  • MDF enclosure – Only the front panel is made of DMC, the rest is made of MDF, another fine-quality material. What makes it such a good choice is that MDF enclosures are great at lowering resonances.
  • Flexible reflex port – One of the reasons why the bass created by KEF LS50 is so awesome is that the elliptical reflex port that tunes the bass is flexible. And because of that, there are absolutely no distortions when dealing with mid-range frequencies.


  • Fantastic sound – If you’ve used only budget speakers so far, you’re gonna be shocked by the quality of sound created by KED LS50. The performances of these bookshelf speakers are fantastic, regardless of the frequency. And considering their pretty small size, it’s really shocking that the bass they create is so impressive.
  • Small size, lovely design – In terms of design, KEF LS50 are bookshelf speakers in true sense of the term. First, their size is pretty small, so you won’t have problems finding a place to keep them. Secondly, KEF LS50 speakers look pretty stylish, meaning that they won’t draw attention to them. Of course, only until you switch them on.
  • Durability – These bookshelf speakers are made by a manufacturer that’s trusted by such reputable institutions like the BBC. They like KEF not only because its speakers create amazing sound, but also because all of KEF’s products are super-sturdy. And that, of course, includes KEF LS50 as well. These speakers are bound to serve you well for ages and even if something goes wrong, the manufacturer is obliged to repair it, under the condition that the problem has occurred during the first five years since the purchase date.


  • Price – Many average users simply have no intention of spending more than just a few hundred dollars on a set of bookshelf speakers, nonetheless over a grand, which is how much you’d need to pay to get KEF LS50. But, if you’re not an ordinary user but a true audiophile, the price tag will not stop you from getting some of the best speakers in the world today.
