What makes KEF LS50 Wireless so special?

The LS50 Wireless follows the trend of the famous BBC LS3/5a monitors. It has 3 unique technologies responsible for powerful and spacious sound, they are constrained layer damping, curved baffle, and elliptical reflex port. The first technology eliminates the enclosure from vibrating and as a result, prevents the coloration of the mid-range.

To reduce reflections and vibrations, the curved baffle is designed with a special shape. The 3rd one is a port that has a flexible inner surface that stops longitudinal vibrations. While conventional port tubes suffer from turbulence, the flared port eliminates this issue as well.

KEF ls50 vs Sonos Play 5: How I differentiated these speakers


The new Sonos Five has a monochromatic exterior with a graphite grille. The logo is embedded into the shape and it is also humidity resistant so you can put in on the bathroom or out in the front porch.

It has capacitive controls on the top side which means you can swipe across the controls for play/pause, Vol up/down or to change the track to previous or the next one.

KEF LS50 Wireless is compact in size with the sturdy build quality. The ‘FEA-designed’ cabinet with MDF is built such as it will not allow any resonance or vibrations. The front side is curved and is made of polyester resin with fiberglass and calcium carbonate. It has touch-sensitive controls but doesn’t come with a grille.


One of the biggest differences in the audio quality of the Sonos Play 5 vs Sonos Five is the bass. While the bass of Play 5 wasn’t too bad, it wasn’t too impressive either. But with Sonos Five, even the heavy-bass enthusiasts will be satisfied without adding a subwoofer but you can add a Sonos sub if you want.

Despite its size, the Five is built to be ideal for large open spaces. The audio quality is something you can’t question about. It has extremely-well tuned treble, bass, and clear mid-range. The left and right angled-tweeters are responsible for a wider soundstage and clear highs.

The audio is rich and well-balanced and isn’t harsh. You can play music at a very high volume without any distortion. You can adjust the EQ settings in the S2 app for treble and bass. If you shift to wireless stereo pairing to pair two Five’s, the cost will increase but you will get immersive full surround sound ideal for movies.

The KEF LS50 Wireless is known for its outstanding performance. It has detailed and crystal clear audio which is not bright or harsh but very neutral. The dome tweeter has a ‘Tangerine waveguide’ that delivers a broader soundstage.

The patented Uni-Q drivers deliver a wider sweet spot with detailed sound and these speakers are ideal for small to medium-sized rooms. The audio will not be muffled or you will not hear any chuffing noise due to air turbulence because of its special design of tubes.

Product Differentiators

The Sonos Five is the company’s largest, craziest, and most powerful speaker, and it has snatched most of the Play:5’s spotlight. When evaluated as a standalone wireless speaker, it’s tough to dispute that the Play 5 has been surpassed in terms of sound quality by the more costly Klipsch R-51PM. Despite the fact that the multi-room system, of which the Play 5 is a vital element, this remains our favorite Sonos’ flagship speaker.

These KEF Wirelesses are far more than merely active versions of the LS50s, which have won several awards. They’re a full system encased in a beautiful packaging. It’s nearly identical to the Klipsch The Sixes, with the exception that the Klipsch has a phono preamp built in, but the KEF will require a separate phono preamp.
