KEF has released a pair of high-end speakers in its LS50 Collection that are the first to use "Metamaterial Absorption Technology," with one model including support for AirPlay 2.

The KEF LS50 Meta and LS50 Wireless II are bookshelf and wireless hi-fi speakers that are upgraded versions of earlier models, with KEF claiming to have worked on the improvements over three years. The new models are high-powered and are said to be capable of creating an "authentic and natural sound," regardless of the content playing through them.

The headline change for both models is the use of Metamaterial Absorption Technology (MAT), a synthetic material that has a complex maze-like structure capable of absorbing 99% of unwanted sound emitted from the back of the driver. Its use results in a considerable reduction in distortion, beating traditional techniques that typically absorbs around 60% of the unwanted noise.

The LS50 Meta consists of a 12th-generation Uni-Q driver array, with a point source configuration that aims to deliver an even sound throughout the room. It consists of a 25mm high-frequency tweeter with a vented aluminum dome with MAT applied, accompanied by a 130mm aluminum cone woofer.

Capable of taking up to 100 watts of amplification, the speaker can output up to 106 decibels of sound. The use of a rigid cabinet helps to radiate sound without any further interference, with the use of a baffle produced from an injection-molded Dough Molding Compound usually used in the automotive industry, and further cross-bracing to deaden internal vibrations.

Accompanying the LS50 Meta, the LS50 Wireless II offers similar styling but with improved functionality. Housing a 100W class A/B amplifier for the tweeter and a 280W class D amplifier for the mid and bass driver, the speaker outputs a lot of power, and can do so at up to 108 decibels.

Connectivity options extend to cover HDMI eARC, optical, digital coaxial, and normal analog inputs, as well as Ethernet ports used to connect it directly to a network, as well as between speakers. The speakers can also connect wirelessly, with its built-in Bluetooth 4.2 and Wi-Fi 802.11ac support.

The speaker line network connectivity also brings compatibility with streaming services, including Spotify via Spotify Connect, Tidal, Amazon Music, Deezer, and others. AirPlay 2 is also available, allowing the system to work with other devices that support it, such as an Apple TV for a home cinema.

The LS50 Meta is now available, priced at $1,499.99 per pair, and offered in four finishes including Carbon Black, Titanium Gray, Mineral White, and a Royal Blue Special Edition.

The LS50 Wireless II will cost $2,499.99 per pair when it goes on sale on October 11, and will be offered in Carbon Black, Titanium Gray, Mineral White, and a Crimson Red Special Edition.

Bespoke S2 Floor Stands are also available in each of the speakers' color ranges, priced at $449.99 per pair.

    I currently own a pair of passive LS 50s and are very pleased with them. I drive them with a recent Denon AVR receiver. I would however like to ditch the receiver and have a more integrated set up. 

    I would jump all over the wireless 11 LS50s, but for the horrible reviews concerning connectivity issues and a very poor app integration. 

    I’ll wait for the reviews before considering purchasing these speakers. Let’s hope for considerable improvement in the software implementation.

    The original LS50 vision is to make a speaker as good as the iconic Rogers 3/5a. KEF never reach its goal. 

    The 2500usd price tag is really steep for a pair wireless speaker. There are many choices for that price range, which I get a whole mini system.

    Yeah what’s up with the Bt 4.2 already? Also USD$2500 seems a bit steep for what they are, although I suppose that includes the amps.

    These look promising. $2500 does seem steep, but all the electronics in them doesn’t come cheap. 
    KEF does have sales a couple of times a years, so it might be worth waiting for the next one.

    I have a pair of KEF’s LSX wireless speakers and KUBE 10 sub-woofer as a bedroom system.
    The sound quality is quite good and I’ve been really happy with them.
    I use them to stream movies from my iPad or iPhone with a 32” monitor or music from iPhone or Mac.
    I must say, it’s certainly nice to have wireless speakers that aren’t black. Mine are green. 

    On the downside, the wireless implementation can be finicky at times. 
    It does take 20 seconds or so to establish a connection.
    Occasionally, they drop the signal or need to be “restarted” in order to get a connection.
    It’s a bit irritating, but the pluses outweigh the minuses.

    What an upgrade.

     Although no Bluetooth 5.0 and WiFi 6. 

    I think ac is good enough I hook an Ethernet cable up anyway.

    I think the price tag is a steal for what it is. Superb dac, fine tuned amplification and great speakers. Less cable and fine tuning via the app. 

    Make no mistake the lsx sound like a toy against this. It is not for your desk! Its for an amazing tv and music experience! 

    For music a 5.1 is ridiculous. Music comes from the front! No band is surrounding you and they do that outstanding at least the old ones. This ones must be mind blowing
