KEF LS 50 Meta review and comparison with the LS50
The original KEF LS50 was one of those landmark speakers, a pocket rocket which performed at a much higher level than what it’s price tag might indicate. The original LS50 has been widely reviewed, and is well regarded by audiophiles everywhere.
However it does have some bite in the treble and lacks some deep bass, and works better for music which does not go too deep or with a sub to reinforce the bass. But what it does have is fabulous imaging, which allows you to how off great soundstaging, depth, and definition. If you are into details, you’ll love them. The coaxial design is also wonderful for those who sit a bit off axis. The construction is a marvel in itself and with a modern design, a beautiful gloss finish and a quality build. No wonder it’s loved by music lovers the world over.
Now recently KEF has introduced the new KEF Meta. This is an updated version of the original and whilst it can look deceivingly the same, there are significant differences.
First a link to the official website:
So what remains the same?
Firstly the cabinet and driver dimensions are the same, and the new speaker is still a rear ported design with plugs, but they prefer if you use them with some distance away from the walls.
Now for what’s different
What is META
This is the key difference and this is from the KEF site:
“Metamaterial Absorption Technology
A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology (MAT) is a highly complex maze-like structure that absorbs 99% of the unwanted sound from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound.”
The KEF coaxial driver used is the 12 generation and it works well. I have been using coaxial designs from them for since the Reference series from the 90s.
But the main thing is, how does it sound?
I had the opportunity to try out the new LS 50 Meta recently alongside my LS50.
Partnering equipment:
Marantz PM 11S3
Cambridge Audio Edge NQ
Kimber 8TC
Music was provided via Apple Lossless iTunes and the USB playback.
I like to use a drum heavy track from the Usher speakers demo disc, as well as the acoustic version of “Everybody Hurts” performed by the Corrs. I have a high resolution version of this and it shows off imaging well and if the treble comes in hot, you will know it. If the soundstaging is done well, you will be able to pick out the four members of the band, as well as some ambient noises from the venue at which it was recorded.
The LS 50 Meta – which I will call the Meta from now. Has a rather solid cabinet, and the build quality is as good if not better than the original. No issues here. The matt paint will survive the fingerprint test better than the original glossy finish but you may prefer the gloss finish.
What you retain is the wonderful imaging, soundstaging, and depth. But, it seems to be a bit clearer, and the treble is sweeter, less grating and the integration between the highs and mids is better. Now the new speaker is more forgiving of amps, but it is still more on the bright side compared to soft dome speakers like the Dynaudio Special 40s. The bass has the same qualities, but also does not go that deep either.
What impresses is the resolution of details and you will find very few competitors in the same price range which can give you the same resolution. It is still a small speaker, with a small woofer, but if you are willing to partner it with a good sub or use it mainly for vocals, instrumentals or small group jazz, it will do pretty well.
In addition, if you are into home theatre, this is going to be a very enticing option. You could use the same speaker for all the channels and still retain enough change to buy a good subwoofer or two.
So it is better than the original? The sonic signature is a bit sweeter, and will appeal to those who want good detail, but eschewed the sharpness of the original.
Spot the difference.... the Meta is on the left.
However it is still not easy to drive, and will still benefit from quality amplification, and a good source. I am sure KEF will sell it by the bucketloads.
