I don't normally buy speakers as I DIY, but I'm tempted to get a pair of these as a reference for future builds.

Hi Erin. I'm working on getting my brand new bass technology ready for market. It's going to remedy the crux of the bass limitations forever. A few recordings are posted on my channel that should leave many people scratching their heads in temporary disbelief. Two of the recordings offer a good depiction of what it's like in person. The indoor video and the 2nd take outdoor recording. Thanks for giving my work a look see. Cheers!

That compression response linearity graph is cool. The low end looks like it could be a cone breakup measurement. Olive and Toole talked about cone breakup as much more perceptible than THD. I wonder what Accuton drivers look like on this graph.

Looks like it is about coaxial speakers these days… looking forward to Ascendo review 😊

I've thought about doing that with ported setups, but I've always questioned how useful it can be. I have a new project that's running a very small 5.25" subwoofer, and it's the first time I'm planning to run a shelf like this just to get the F3 low enough. I haven't decided if I'd try for more than -3dB though. It's one of the few things you can do to really extend sensitivity of a midrange woofer into low frequencies. If they tuned in a standard way, so flat until roll off, they would likely be stuck with a F3 quite high, possible 80Hz or maybe 70Hz. But as a bit of a trick to extend low frequency existence (and I mean existence), you can run an overly large enclosure and tune the port lower than normal. This will create that shelf. Then you push it as far as you can go, and there's still a pretty hard limit. Picking the drop is a judgement call. Do you set the shelf at -3dB, -5dB, or opt for something different. When I mentioned existence, at so many dB down, you won't really perceive that output over the rest of the music. So you really only have a small range you can get away with to hold sensitivity before it's basically not useful. You can play with that virtually with an EQ. You can EQ down the bass on a speaker set or headphones and play with a shelf like this, cutting out a few dB, then a couple more, and eventually that low end response isn't loud enough to be useful. You can cut more, even a lot more, and barely perceive additional loss. You've lost too much presence to be useful. This shelf can work the same way. It's neat, but it has a limit. You mentioned room response, and that is a saving grace if it's there and enough to help this low end out. It's a neat process because it can help the bottom end quite a bit. You might be able to gain another 20 or 30Hz down which can be HUGE for low frequency presence and body. There is a big negative to this though. The small woofer still only has so much excursion to work with. Even if you extend the shelf for sensitivity, you will still hit an excursion limit, and you may have to manage this in some way. Shelf or no shelf, there will be a hard wall you can't fix. You've only got so much excursion to throw at low frequencies, and that shelf is not helping you out. The sensitivity is there, sure, but the SPL capability drops. And you can see this limit higher up in the frequency band, not just the very bottom end. This is very likely why you are seeing that big dynamic compression spike higher up. That's very likely the first excursion peak in that enclosure. This product is a good example of tone vs flatness. We are often remarkably bad at tonal memory, so it's easy to have an overall warm or overall bright speakers, spend only a small amount of time with it, and you will auto tune mentally to neutral. We perceive non-linearity well. We perceive slope poorly. You can have quite a few dB bright or warm on the ends, and if the response curve is flat, it will typically sound "neutral." It can be hard to decipher this without having some reference comparators that are known quantities. You see this more readily if you go back and forth between it and the reference devices (other speakers, headphones, whatever). It will immediately give you a stark difference of warm, bright, etc. when compared that isn't easily perceived otherwise. Tone like this can also be a tuning method of compensating for the note body/weight. A speaker that outputs a thinner bass note can have this partially countered with a higher low frequency dB level. This is done quite a lot with IEMs because many BA based ones or even some dynamic driver ones run very lean bass notes. You can add a few dB over the lower frequencies and pump up those energy levels. Often, this tricks our minds well enough for it to perceive it as "full" and with good authority. This bump makes it "sound even" to our brains. The bass can even come across more crisp and articulate than normal because the note is actually leaner and boosted. It can sound good, even authoritative. This is something Kef might be doing when tuning the speaker this way. Even though I've never heard one, I can make a pretty strong guess towards it, especially if you're perceiving it as sounding neutral. You can often have pretty excellent low frequency clarity this way, but you might lose a bit of texture and even some of the 3-dimensional presence cues that are in those notes. We often have a lot of soundstage room cues in these lower notes. This can affect others stuff like instruments where a cello might sound a bit thin. It's a trade-off. The thinner note can be useful for noisy rooms. The leaner bass isn't overly boomy in a poorly treated room. It will always sound cleaner than other speakers in the same room. However, the thinner note can make the speaker sound "small" if it's not compensated well enough. Usually to test this I like to use a pink noise track and EQ to what I perceive as flat. Then I'll play music. When the driver is thin in body in lower frequencies, it will come across sounding bright. Pink noise doesn't care about note thickness so you are actually tuning flat for loudness, not note characteristic. So when you go back to stuff that does like music, it's really apparent. This is a good tool to gauge aspects about body of note or even energy of presentation, and it shows some of what sound engineers are doing to compensate for driver shortcomings. The driver might be picked or tuned for certain desirable traits, but there may have to be some compromises and compensations to make the package work good as a whole.

Thanks for the review Erin. I currently own both the revel 126be and the 226be but have previously owned the original kef ls50 and R3. Although I think both revels are phenomenal speakers I plan on selling the 126 and bring back the either the meta version of the R3 or the ls50.

Something more similar to the LS50 suit their design aesthetic and room/interior design sensibilities. And if you are an audiophile type with a $6K+/£5,500 budget, you're most likely going to be more attracted to something a bit more "exotic" or unique from a boutique HiFi brand.

Now I realize I am comparing 8k speakers to 2K speakers. So it's not a fair fight. However I felt the R3 Meta was a great speaker. It was just a little thin in the lower vocal range and upper bass. It also sounded small in my living room. I could not get these R3 Metas to completely disappear in my living room.

I like narrow dispersion speakers because less sidewall reflection. Granted if you toe them out you will get more sidewall reflection.

I find my LS50 to be a little bright when they're pointed directly at you. Somewhere between there and pointed straight into the room is where I prefer them. When I first got them, I was wondering if I made a mistake for my listening preferences. Glad that a little bit of moving the speakers around and adjusting toe eased my concerns. I do think the R3 is by far the superior speaker for the kinds of music I listen to. For the LS50, having a coaxial midrange / bass driver with a chunk of its surface area taken out for the tweeter is demanding a lot. The poor LS50s just can't keep up with all the content in the music (lots of mids and bass in technical death metal). I mostly listen on planar headphones these days.

Is there a reason you don't recommend extremem toe in (toe in frot of the listener)for time intensity trading? Toeing out reduces your sweet spot but gives you wider sound stage while toeing in widens the sweet spot but narrows the stage a bit. I run without a center channel with 4.2.2 setup. I like the toe in effect as it just really locks that phantom center imaging in. It also helps when you move about the room if your toe in is aggressive enough. You always get to enjoy both speakers that way.

Erin's measurements indicate that both the Dynamics and Distortion of the R3 Meta would be significantly improved when combining these with a good subwoofer, especially if you have a large-ish room and want to listen at higher volumes at further distances. And of course, nearly any standmount speaker will benefit from adding a subwoofer for the same reasons. But I get what you are saying about some speakers having a "plasticy" or unnatural sound. I demo'd many pairs of different studio monitors in my home studio before settling on a few small & large monitors for nearfield and midfield listening exactly because of this (I'm a saxophonist & drummer/percussionist). In the end I was able to find excellent monitors. But many that I demo'd did not sound natural and lifelike to my ears. However, I ultimately designed my own DIY 3-way studio monitors for about 1/4 the cost and sold the ATCs, and couldn't be happier. ​@JamesWilliams-gf8gm To another point that was discussed here, I've measured quite a few loudspeakers, albeit using the more traditional processes without a Klippel NFS, and I've found that loudspeakers that exhibit "Glare", especially when it worsens with increased volume levels, are due to several factors 9 times out of 10... (Keep the Fletcher-Munson curve in mind here). Usually I've found that "Glare" is experienced when listening to a loudspeaker that has an already slightly lifted upper treble response. This might give the speaker the perception of "better detail & resolution" at normal levels and not be bothersome. But when the volume is increased, our sensitivity to this lifted treble response simply becomes too overbearing. ^So there's that, and/or increased Distortion when the volume level is turned up becomes the cultprit. Thirdly, YOUR ROOM i.e. listening environment, combined with the directivity of the speaker has a large influence on this, obviously. Here is just one example I experienced for myself: Several years ago, I went over to a friend's home studio to do some tracking for a project he was working on. He's a vocalist, guitarist, and keys player, and I was adding some small percussion elements (shaker and tambourine) and saxophone to the mix. I had already tracked the drums for him in my own home studio. He had been to my home studio and heard my smaller studio monitors previously, and after listening to some of his own mixes on my setup, he decided to buy the same small studio monitors that I was using at the time (Neumann KH 120A). However, when I listened to the playback of our tracking session in his room and setup, his Neumann's just sounded much more grating and completely "unnatural" compared to what I was used to in my own studio. Granted, I had done quite a bit of selective acoustic treatment in my room, as well as a lot of measurements to shape the response, which cannot be underestimated. But his room was also moderately "dead" and used a fair amount of acoustic treatment. So the first thing that I checked are the Bass, Low-Mid, and Treble "trim" switches (essentially a high-, mid-, and low-shelf filter) on the back of his monitors. But they were all at the "0" positions, not boosted or emphasized. So that wasn't the main cause of the glare and unnatural sound. What it ended up being was a myriad of reflections and their resulting comb filtering off of the front surface and side edges of his large 47" HDTV Display monitor, as well as additional reflections between the back of the monitor and the front wall. Have you ever been in a somewhat "lively" room with tile or hardwood floors and no carpet, then clapped your hands and experienced the "boing" reverberation slap between the floor and ceiling that sound so weird and unnatural? It seemed that something similar was happening here, but at shorter intervals/timing, and at higher frequencies where the effect or cause wasn't immediately discernable. He was using the large HDTV display as his main display monitor for his DAW, and it was centered above his mixing desk between the two Neumann studio monitors. I asked him if he had a large and heavy/thick bed blanket or goose down comforter, and he did, so we folded it in two so it was double-layered and simply laid it completely over the front & back of the large HDTV display.... Voilà! Now we had Natural, smooth, LIFELIKE response. :) This also helped to improve the perceived Dynamics. So this is just one example where the room, placement of the speakers, and the loudspeaker's unique directivity attributes can have a huge effect on the perceived sound. Another thing to mention...and most of us "Golden Ears" hate it when this is brought up...Confirmation or Expectation Bias. There have been combined sighted+blind listening tests, that when listeners could visually see the loudspeakers that were playing and they had bright, "silvery" aluminum cones, tweeter domes, and white cabinets, they would indicate that these speakers were way too bright and harsh compared to the others that used traditional black cones and natural wood veneer or black cabinets. However, when an acoustically transparent, but opaque "grill cloth" screen was hiding all of the speakers, and the speakers were switched at random (A/B/X), the listeners then chose those same white/shiny aluminum cone speakers as their favorites by a large margin. SOMEHOW, they magically became Smooth & Balanced, and not harsh or "bright" at all when they could no longer see them. 😜 This is similar to the results that Floyd Toole and Sean Olive documented in their sighted vs blind listening experiements at Harman/JBL. Just search for and read the following: "seanolive-blogspot-2009-04-09 The Dishonesty of Sighted Listening Tests"

@@bbfoto7248 good read thanks. I think you are correct on glair. I have two speakers (and others) from the same designer/company right now (JBL 4367 and JBL 590) and the 4367 is 100% free of glair at any volume and the 590 will walk me out of the room if played over 87db with an aggressive bit/glair. the 590 has a slight rise in the treble to my hear and the 4367 has a light roll off. The distortion is probably a lot less on the much better compression driver in the 4367. But I can’t say I really hear or understand what distortion sounds like. Just that the 4367 is incredibly “clean” and dynamic at any volume I demoed the Kef Reference 3 a few times. It was an ok speaker but not worth the money when compared to other brands at the same cost. It did not sound natural to my ear regardless of doing everything “right”. It just seemed to lack dynamics at all frequency and the highs are pretty average at best. The Revel 328be was better in every way to my ear and for only $1000 more (6%). I bought the 228be and used them with subs for awhile, before moving on to JBL. Kef is kind of a lame duck to me but people seem to love them. I often wonder if they have done direct A/B or maybe they just value different sound aspects than me.

@@JamesWilliams-gf8gm There are some listening tests that you can download that teach you how to listen for and detect distortion. JBL/Harman also has their "How To Listen" series. And the old Autosound2000 Test Discs # 1-4 by David Navone and Richard Clark also had a series of music tracks that would introduce consecutively higher percentages of distortion with each track so that you could hear what to listen for and then test your own limits or threshold for hearing it. It's like a lot of things...once you hear some examples of different types of distortion, you have that "aha moment" and can then instantly recognize the attributes and audibly detect it when you hear it again. Especially at higher listening levels, distortion is what is most often perceived as "glare" or "harshness" IF the loudspeakers or headphones are otherwise balanced and neutral.

Excellent review, really liked the comparison to other speakers at the end. Specifically for home theater use, although not necessarily in the same class, I can't seem to think you'll do better than the Arendal 1961 bookshelf especially considering you're buying in multiples and they're sealed. Do you concur? Really looking forward to the 1961 monitor review!

The KEF does a better job with vertical uniformity, if I recall correctly. If you're going to be using the setup in a home theater with subs then it might make more sense to just go with the Arendal and cross them at about 100/120Hz (assuming you can get away with it with your subwoofer position).

@ErinsAudioCorner I've got a couple JTR RS1s so I feel like I could probably get away with 100hz max before running into localization issues.

Agree that original was a little too bright. Good to know the fixed that.

The hard decision is which color. I really like the white on my R300s, but the R3 Metas look really good in piano black with the dark grey baffles.

This is great! Any chance you could get a pair of the KEF R11 Meta in to review?

When are KEF going to make an active wireless speaker in this size and 3 way format? Maybe a little larger to accommodate the amps.

I think the speaker designer Richard Vandersteen has been saying for years never to listen to a coaxial driver straight on. He said it is much more cohesive when it gets listened to just a bit off axis.

Thank you once again for a thorough and informative review. Assuming a listening arrangement that forms an equilateral triangle between the listener and the speakers, would 10 degrees off axis equate to a 70 degree angle to the front wall, as 60 degrees relative to the front wall would be directly on-axis?

@ErinsAudioCorner

The triangle itself would still be the same 60 degrees. However, you would simply turn the speaker 10 degrees out (say, pointing at your shoulder instead of your head). Hope that helps clear things up.

Thanks for that, I think I’m on the same page, just didn’t explain my thoughts as eloquently

Wondering how the Ascend Acoustic LX would stack up against this one?

Nice work! Love the nearfield flexibility of coax platforms. What a solid performer you've got there. KEF has been iterating/optimizing their coax Kung-fu for a very long time. Curious; if a sub is warranted, why not get the LS50 and utilize the several hundred dollars on a sub? I always thought an LS50 platform supported by both mbms, and subs, could be aligned/tuned to be fantastic. I'm told the coax coherence of the sidewall energy enhances the experience, apparent source width, etc. Good question for Jack Oclee-Brown, ... or Erin. Nice work. Nobody's out there doing what you do ... bringing what you bring.

I would have to do some listening comparisons, and also look at the data. But I believe the R3 has smoother response. The fact that the surround of the coax mid range is more smooth hence at its purpose. Which, I’m sure you already know. I don’t think there is much price difference between the LS 50 meta and this speaker, is there? Maybe about $600? if that’s the case, I think this one still wins out.

One of important things that you don't talk about it is speaker impedance it shows better then sensitivity , if its reactive load has more capacitive , it will be harder for amplifier to drive it , you get normally higher THD. Inductive load is easier then capacitive load. I measures with my AP555 ,amplifier with speaker load ( according to sterophile simulator speaker load) and it show that when it becomes capacitive load ,we get higher THD . If we hade less variation in impedance phase it would be better and easier for amplifier.

Erin, very informative. I see how the measurements compare to your earlier ones of the KEF Reference 1, but I wonder if there is anything in addition that you heard as different? Ignoring cost difference, could you live with either one just as easily?

Great video, thank you 👍. I am in the market for a new speaker system to cover both “pure audio” and 5.1 home theatre. It looks like the R3 Meta would make a great pair of front speakers. Could I please get a recommendation for centre, surround, and subwoofer speakers that would be a good tonal match for the R3 Metas?

@ErinsAudioCorner Apologies if the question has already been asked, but what amplifier or amplifier types would pair nicely with these speakers? an amplifier on the warmer side perhaps? Thank you

I wonder if they could make a grill for them that absorbs high frequencies a little bit more right down the middle of the fabric, so that you don't get that high frequency bump on axis? Then you wouldn't have to worry about toe-in or toe-out with these speakers.

@ErinsAudioCorner

Grilles can do that but they typically create more problems by nature of diffraction (having an edge sticking up above the driver creates reflections that interfere with the direct and off-axis sound).

How would you compare these to the 400 MKII speakers? Both are around $2000.00

Right now you can get a Kef r3 for 500euro, a Kef r5 for 800 euro and a Kef r3 meta for 1100 euro (single speaker). Is it really that much better? Dealers want to get rid of the 'old' speakers and im really tempted to buy a pair of the 'old' r3 (or the r5?)

Hi there Erin, really enjoyed your review. I am new to the channel and from what i have seen I really liked that you are relaying on data not subjective bla bla review. I had r300 plus arcam A19 amp and arcam ir dac for 10y and lately I was thinking to update my system. At first j was thinking for streamlining my set up by buying one box solution for amp+streamer+dac for example yamaha rn2000a as my wife is complaining about the many remotes and boxes. Then i saw the Buchardt anniversary 10 and i said this might be but in the same time there are the new R3 meta....I liked the r300 and they fit it my small living room very well even with only 15cm from the wall but i always felt that though revealing as hell i missed some excitement (i am low volume listener). Do you think i will gain more from R3meta plus new all in one more power amp all for around 4k or buchard a10? I really dont want to invest too much time it finding the perfect match with R3 meta .... I need the speakers to be good all around ... movies, games and jazz/vocals some rock and pop. Thanks in advance for your reply much appreciated...

They R3 is a very neutral speaker that is true to the source. The Buchardt likely is as well. Since the Buchardt is active it will get lower in response but will likely have a built-in limiter that will cut the bass as volume increases. I’m supposed to get the A10 for review in the near future. But that’s all I can go on for now.
