The slogan sums up KEF's long history of accomplishments in the field of home audio music systems and what KEF has in store for audio-heads in the future.

KEF and the BBC

Kef LS50 Wireless Speakers In This Review Rear ViewYou've got to love that KEF have had enough commercial and critical success over the years to have its own hi-fi speaker museum devoted to the company's legacy. You’ll find KEF speakers are designed in a province of Britain and are renowned in audiophile and professional circles as the creator of some of the very best hi-fi speaker systems available.

KEF’s long time success in delivering flawless sound is an amazing story and worth learning a about if you're interested finding the best of audio systems. 

Our amazing story about KEF happened long ago and across the pond. It began when the global broadcaster BBC needed a partner to design full range speakers for proffesional use and KEF’s success started by satisfying the needs of professional organizations.

In the 1960s, 70s, and 80s, this global broadcaster had both demanding standards for sound quality and many specific use cases for the speaker systems they imagined KEF building for them. Our story is very similar to the challenges you will face building your own home music system, so please listen up. Back to our story.. The BBC was commitment to research and development with the goal of excellence in sound reproduction. It was serious business and was decided KEF was to design and build all of the pro monitor speakers they would use in the field and studio.

The result of the relationship is KEF/BBC designed and built rugged speakers in both large and small enclosures that were built for inside and outside use. Most of these monitors would be used by the BBC for monitoring and recording broadcasts, mixing live shows, events, and concerts.

These pro speaker monitors had to meet tight tolerances because they needed to exactly reproduce the sound and dynamics of cannon fire, symphonic or popular music played live, and actors dialogue. The audio technicians needed speakers to hear all of this with the greatest of accuracy, across the audible sound spectrum, and at various output levels.

All this professional design work eventually led to products designed for to be part of home music systems. With KEF’s meticulous designs music lovers at home were in for a very big sonic surprise.

KEF LS50 Wireless Speakers Review Top Rated for home audio

It all started with the diminutive KEF LS3/5a broadcast monitor designed to be used in cramped BBC broadcast vans. When presented to consumers the BBC LS3/5a monitor speaker turned out to be KEFs breakthrough home Hi-Fi product. KEF sold 50,000 pair worldwide because something was very different sounding, in a very good way, when it came to these diminutive KEF's.

The audiophiles who coveted large speakers suddenly got some bad news. The bigger and heavier the wooden cabinet (that were all rage, and still are) sounded distorted and confined inside the cabinet compared to the open sounding LS3/5a! These big speaker enclosure sounded "boxy" or even worse, a bit muffled sounding compared to this petite box called LS3/5a.

Back then, the big floor standing speaker market was replete OEM tweeters of high quality. Unfortunately, the other speakers matched with the tweeters combined with the large wooden enclosure created an audio disconnect. The best speaker designers knew, the bigger the speaker the bigger the audio problems.

Like a live performance, listening to these tiny KEF speakers the music sounded alive, all in sync, with the sound hanging in thin air. With that set of abilities, the KEF LS pro mini-monitor was born and is still here today for you to cherish and enjoy.

It’s not surprising that KEF moved on from the LS5 with future designs. Although, it is a testament to brilliance that even though the L5 was designed in the sixties, the sound is so amazingly good that right now you can buy contemporary clones of this lauded speaker from commercial hi-fi companies including Harwood, Spendor, Falcon and others.

Not All Active Wireless Speaker Systems are Built for Greatness

KEF’s classic speaker design meets the future with the LS50W Active. Knowing a bit of KEFs history should tell you the company is almost the point of origin for audiophile grade monitor loudspeakers. Now we will talk more about what lofty goals in speaker design looks like.

Uni-Q Tweeters and Drivers

When KEF designs something new we always take notice and have always been amazed by the sound of the KEF tweeters - In the LS50W Active, the tweeters are part of the company's latest aluminum/magnesium Uni-Q time-correcting drivers used throughout the KEF speaker lineup. Simply stated, it has musical detail and disperses a large sweet-spot giving you placement flexibility in your living space. For the desktop or in a larger listening space you'll enjoy punchy drivers tight bass performance and transparent tweeter sound giving you a “multi-dimensional soundstage experience”.

LS50W's are uniquely tuned for either listening as a desktop setup, in an open living room or near a wall. If overall sound quality (SQ) is of importance to you make sure your systems tweeters are up to the job. Don’t compromise on the excessive brightness associated with many cheap tweeters. If you listen all day to music a good tweeter like the 11th generation Uni-Q drivers will provide a rich detailed sound signature and will make long listening sessions a true pleasure.

A Complete Audiophile System is Built In the KEF LS50W Wireless Speakers

Bringing professional studio monitors to the home music system continues with the LS50W Active. With KEF’s meticulous engineering and the addition of active power and a wireless connection delivers high-end Hi-Fi for your music, games and films.

Audiophile demands meets modern convenience best describes KEF’s LS50W power for lifestylers in need of hig-end audio. It is all about your ears and KEF boasts it has one of the most sophisticated audio systems ever built into a pair of speakers. Setting new standards and combining state of the art acoustic design with a built-in streaming preamplifier, four dedicated DAC’s covering each channel, and four dedicated bi-amp dual mono amplifiers that are all factory-optimized components built-in the LS50W.

These individual amps provide 400 watts of Class D power for the bass and midrange and 60 watts of Class A/B power for the superb Uni-Q tweeters. The four separate amplifiers are applied to each Uni-Q driver and the crossover is via customizable EQ and DSP (Digital Signal Processor) with end-to-end 192kHz 24-bit digital signal path let you tailor the sound for your room and speaker placement.

The LS50 Have An InBuilt EQ For Placement Adjustment

KEF's Control App

You’ll have flexible user control with the LS50W via a dedicated iOS or Android app, OLED onboard touch controls and a physical remote control! Using the onboard controls and the app allows detailed adjustments for all the audio corrections for the speakers location and the room type. It's super helpful giving the home decorator in the house more positioning options.

The KEF LS50W downloadable KEF Control App is well suited for intial setup, changing settings, and DSP (Digital Signal Processor) tuning. The setup wizard will get you to your WiFi network and using Wireless Streaming Mode you will be able to do multiple levels of phase correction and room equalization.

What's a Digital Signal Processor?

A DSP is a computer processor that lets you tune your audio system. DSP components were created because audiophiles and sound engineers wanted to adjust the sound for room effects and the location of speakers. The LS50W custom designed onboard DSP along with using the Control App lets you correct for these room variances.

You'll be able to tweak and experiment with adjustments that allow you to set the room size and speaker location. You'll select and adjust room-types. From rooms with low ceilings / heavily furnished to high ceilings / minimally furnished and everything in between. Take your time and listen to your music and no matter if your room is dampened or lively you'll have a simple slider lets you precisely dial in the perfect sound for your room.

Also packed inside the KEF app via DSP is the ability to turn on Phase Correction. The DSP using processing and works with the Uni-Q drivers to time align the music signal with excellent sonic results. To get an idea of of what this tweak adds just listen to music you're familiar with and when correction is active the result is greater resolution and the stereo soundstage will widen in three dimensions.

Do I Need a Subwoofer?

To begin with, you will not find a lot of musical information below 50 Hz in recorded music. TIP: The KEF's also have Bass Extension controls that you can tweak anSmartphone App Use With KEF LS 50 Wireless Top Rated Speakersd you should absolutely experiment with before even thinking about adding a subwoofer. Remember a poorly set-up or mismatched sub frankly can ruin the sound so tread carefully and do your homework before adding a subwoofer.  Still, for music connecting a subwoofer will benifit the bass end extension with some modern electronic, rock, and classical recordings.

Now when it comes to movies and console games sound effects often times you'll have sonic information below 50 Hz. If you're looking for maximum impact with console games and film sound a subwoofer would be the coup de grâce for this KEF audio system. If you add a subwoofer the KEF Control App is very handy for setup and integration allowing you to adjust all of the subwoofer parameters.

System Connectivity 

For CD, Turntable, TV, and game consoles you have a cornucopia of connection capabilities including Wi-Fi, Bluetooth 4.0 with aptX, USB, TOSLINK Optical and RCA Analog connections. You can easily connect up to 12 devices including multiple Bluetooth devices and also switch your inputs using the touch bar on the right speaker, with the bundled remote, or the KEF Control App.

Once that's all done, we suggest using the streaming app or music app of your choice. With our LS50's we used Roon Labs for our music management and Tidal and Spotify for music streaming.
