KEF R3 Meta
Contents
Britain’s KEF has had the R series in its lineup for some time. This version, however, is new. It is, in fact, the META version. And that means that the new “metamaterial” also sees in this R3. In particular, this involves absorption behind the driver. These are materials that do not occur in nature. And by developing your own materials, you have things under your own control, although it is complex. The system looks like a kind of labyrinth. The channels, of course, are all tuned to certain wavelengths. According to KEF, the new META absorber absorbs 99% of all frequencies between 600 – 20000 Hz.
Looking further into the speaker we see a three-way bass reflex system in a neatly finished unit. The cabinet is heavy and solid, which should prevent resonances. At the back we find a bi-wire capability.
The sound
The KEF speakers have a clear signature in sound. It is warm and it sounds polite, there is nothing to offend the listener. If as a listener you like to be on the edge of your seat listening, then KEF is not what you are looking for. If you like to have the music wash over you like a hot shower, then KEF is what you’re looking for. The somewhat polite reproduction also makes the speaker forgiving.
Bass control is very good. With Sohn’s track, the KEFs continue to do their job quite stoically. With the Nilai, the soundstage is large and majestic. The soundstage is set back slightly, which also helps with the relaxed listening experience.
There is an issue with the timing of the music though, the bass clearly lags behind mids and highs. The matching with the Nilai is much better than with the Pass Labs. At least the matching of the KEF speakers with an amplifier is critical, but that doesn’t completely eliminate the timing issue. We don’t know if it’s because the speakers haven’t put in enough hours or if the KEFs’ placement is rather sensitive, but it’s something to consider at home.

Measurements KEF R3 Meta
Boy: that measures well! Apart from some “extra warmth” that KEF adds between 200 – 300 Hz, we see a fairly straight response. Where things go really nicely, however, is distortion. It is incredibly low. Almost all distortion is below -60dB. It reaches close to -70dB, which is unprecedented in this class. That means almost everything we can measure is below 0.1% and even reaches 0.05%. Hats off.
The KEF isn’t really difficult to drive, because we see indeed two humps of the bass reflex system: but it is only 9 Ohm. And the KEF doens’t go any lower than 3 Ohm. A stable amplifier is recommended, though. Especially for the bass.

and…
[ While using the speakers full-range is OK, I found that when I added a subwoofer (SVS SB-2000 Pro and SB-3000, separately), the entire sound became immensely more enveloping. Somehow, it even seems to increase the overall sense of “space” these speakers provide with the right recording. For that reason, I do suggest a subwoofer with these speakers. ]
Makes sense!

I think they still have not solved the problem of the woofer integration with the excellent coaxial, as it happened with the previous model, the R3.
I will listen again to the part of the test referring to them.
Thank you very much (to ALL) for your work.
