[@fidstang]

If you still have access to these, watch for the speaker terminals and make sure they are not lose. I had a pair that kept giving me a resonance between the 200-600Hz range. Took me two days to figure out what I was hearing and running sweeps finally narrowed it down to the terminals. They were loose, couple with the banana plugs, caused the odd resonance I was hearing.

[@init4fun]

Hey, Erin. From your comment, I managed to find this review. I can tell you up front, I haven't heard a bookie that I like, which includes the KEF Metas, largely due to the limit frequency range from the small enclosure. I owned the ELAC Uni-fi 2.0 UB52's, which have the remarkable soundstaging you've referenced here. But one has to work in a sub to reach those missing lower frequencies. I mentioned that I'd picked up a pair of the UF5 Uni-fi 5.1 floorstanders at a helluva price. If you can get beyond the utilitarian cabinet design limitations - these aren't intended to be the most finely finished cabinets - what we're left with is that full range, well-engineered custom driver arrays missing from the bookshelf designs. Once properly burned-in, I was shocked at the low end extension that sounded tight, precise, natural, never colored or bloated. In fact, I often turn my doped-coned subwoofer off and let these floorstanders shine with the well-tuned bass missing from the bookies, as the sub (the ELAC S10.2) often sounds too slow, colored and bloated compared to the tighter, more-acurate-sounding aluminum cone arrays. If you need monster bass in a floorstander, you'll need to look elsewhere. These UF5's are precisely tuned, tight, deep, with a nice kick, but never colored or unnaturally boomy. As I wrote, I'm so surprised and thrilled with the ELAC UF5's at the price, I may stick with them for some time. Their balance and accuracy make competitive w/floorstanders at triple the price, and I've listened to quite a few in the $2k - $5k range. Jones knew what he was doing with the Uni-fi series. Easily, 9 out of 10 stars for me, at this price point.

[@TonicofSonic]

Most underrated KZbin channel since it's conception.

[@Sonofsun001]

FYI - I have these speakers powered by a Primare a30.2 power amp (120w into 8 ohms), there is plenty of punch and bass, quite incredible for the size.

[@mgsamps]

Totally agree, these sounded a little thin for the first week or so, but now after a few Months bass is very strong, you can definitely hear bass goes deeper the DBR62's, it's also more tuneful and faster than the DBR's that these replaced. I pushed these pretty hard in my medium sized room (140w amp) and I dont really hear the compression Erin is talking about, but maybe my amp ran out of steam before that happens, but tbh who listens at that crazy volume for more than a few mins, I do hear "a little" mid bass resonance which might be fixed with a little added damping material to the bass/mid enclosure, but so far very happy with these.

[@magnusdanielsson2749]

Its kinda crazy that an ”average joe” has this kind of measuring equipment while the likes of Stereophile dont.. Keep it up. These reviews are 👍

I don't consider Erin to be an average Joe.

[@BogdanWeiss]

Clearly “not average joe”... Stereophile etc have a very cozy unwritten relationship with manufacturer’s, buy advertising space & you get a + review & HiFi dealers have had most of their profits in cables & other overpriced accessories - this would still be OK, had they been honest & NOT pushed ridiculous accessories & overpriced hype as the only way to high fidelity sound. Ridiculous “reviewers” & overhyped & overhyped nonsensical product, over time have damaged the industry as a whole.

[@magnusdanielsson2749]

@@Feliciano12v well I must admit I dont know who erin is/was before this. I certainly meant no disrespect. I really enjoy his work and the measurements. Ive been interested in hifi for over 20 years and have built several loudspeakers. And I can truly appreciate the value of the measuring equpment he has. I would wish the established reviewers did the same. Soundstage magazine used to have measurements done by the Canadas national research council that use similar methods as Harman Group (wich in turn is similiar to what this Klippel kit does). Well they still do to some extent but not as they used to.

Yay, thanks Erin. I think the designer of the speaker says he designed it to be heard off-axis, or to favor off-axis listening.

[@James7995]

Commercial speaker design is always a study in trade offs. I always imagine the variety of rooms speakers find themselves in and how your try to design a speaker for flexible and imperfect scenarios while remaining capable of a strong performance. It’s interesting.

[@stevenswall]

On axis or off axis, since the 8260, Genelec has solved all of the problems I know of with concentric drivers. I wish more companies would cross things over higher from the woofer to the mids, and get rid of air gaps or diffraction.

[@stevenswall]

@@roger_isaksson Not sure what you're getting at, but Genelec does consider the room with their GLM software. Time coherence wise I don't think that's audible and if it is, having mechanically and DSP aligned coincident driver would be best.

Thank you Erin, Why would someone give you a thumbs down? I always enjoy your video combining your subjective opinion with real scientific measurements! FYI Elac in Germany was only a high company, Andrew Jones revitalized them with the Unifi

[@jeffreybritton3338]

I really appreciate the description of linearity with respect to volume. That is something I don’t usually see talked about.

[@mndlessdrwer]

I really like how the concentric drivers on KEF's iQXX series were configured. On my iQ90 it has a progressively curved cone, so the curvature flattens out toward the edge of the driver and becomes steeper toward the tweeter, which seems to allow it to both project and disperse very well. Unfortunately, it does lead to some issues with near-field listening, but they're towers so that's kinda understandable. I believe their smaller drivers have less pronounced curvatures to their cones. Nowadays, KEF's Uni-Q drivers are a lot shallower, which makes them more versatile but does limit the amount that the driver can truly function as a waveguide. Not entirely sure what the justification is for this change in design, given that I've never noticed any aural anomalies with my towers, but it is what it is. I really want to see someone make a domed concentric mid-woofer using a ring radiator tweeter, since that's basically the only way that you'll get their dispersion characteristics to match up. Maybe something akin to the Devialet Phantom I, but with a ring radiator tweeter mounted flush to the surface instead of their titanium dome tweeter sunk into the voice coil of the mid-woofer.

[@keepingupwiththejones2933]

I will be honest upon introduction to Erin's reviews I was scared away by my own ignorance. I felt like my knowledge base was deficient where the reviews would go over my head. In the beginning that was absolutely true. But I stuck with his reviews. Quite frankly Erin seems to have found an incredible groove where it is technical enough for the true Hifi enthusiasts but he has also put what he hears and measures into terms so even a simple man like me can have light bulb moments when listening to him speak. He has raised my understanding and enjoyment of audio. He had made measurements fun and understandable for me. Something wonderful and quite unexpected. Thank you Erin.

[@IrenESorius]

Best speaker reviewer on KZbin. Ur a ⭐ Erin. Cheers,, 🍻😎👍‍‍!

[@pliedtka]

Looking at the data at Erin's site it's a good design. Both, the bass and mid are metal cone seem to be well behaved. The possibly lower efficiency has most likely do to with the use of ALU cone on the bass unit as they tend to a bit heavier but also stiffer. I quite surprised they run the tweeter down to 1.8kHz without obvious distortions - the distortions rise in a few places at 96dB. I wonder how it fares side by side with twice the Elac price Revel Performa M106 2way design with the Alu drivers.

[@KravchenkoAudioPerth]

@@great100m double the power to get a 3db increase, youll need at least 3 to 4 times the power to percieve double the loudness. Thats a lot of fuckin additional power we are talkin about here. Imagine a needing 400w per channel to get it to go twice as loud from 100w per channel. Thats insane power (and money). Lesson here; if loudness is important, begin with a sensitive speaker. Just not Klipsch.

Quality review. Seems elac has another winner but subs required and big amp required.

[@juanmillaruelo7647]

Yep. The new concentric is out of the "mid" slot. It goes to 1000€. PLUS, the cost of a new amp to feed it. 80-100 wpc will not be enough. Some people may drive it with a Crown 2502 until they save up. Makes you understand the people who buy BIG speakers that "sip" power. comparatively speaking.

Hey Erin, what kind of smoothing do you see for this measurement on the ELAC Uni-Fi Reference UBR62 Bookshelf? It's nicely detailed from about 200hz and above. If you EQ'd this speaker from a nearfield response would you want to fix that low bass thing at 100hz to 180hz ish?

[@ErinsAudioCorner]

1/20th-octave resolution, per the CEA-2034 standard. I'd measure the in-situ response; you may not need to fix that dip if you happen to have a natural boost there due to room/placement.

[@hdmoviesource]

@@ErinsAudioCorner thank you very much. You didn't happen to measure the original Unifi speakers did you? I'd like to see if my measurements were the same. I took a nearfield measurement using MMM, and then a MLP, and calibrated to a Harman Curve and they sound very good. Much better than the uncalibrated sound.

[@tnargs57]

Hi Erin, regarding your 11m15s comment about Schroeder frequency…. what you actually mean is the transition frequency (or transition region). The Schroeder crossover frequency doesn’t apply to small rooms like home hifi, and if you try to calculate it from measurements in a small (i.e. domestic) room, you get low values that are too low to describe what you actually wish to convey, namely, the frequency (region) below which room modes dominate and above which reflected sounds dominate. This is referred to as the transition frequency or transition region.

[@ErinsAudioCorner]

Maybe I'm misunderstanding your comment but the Schroeder frequency is the transition frequency. I've always seen them used interchangeably. Even by Linkwitz in the example below: www.linkwitzlab.com/rooms.htm Also, page 149 of Dr. Toole's book references them as the same. (I just double checked)

[@tnargs57]

Wrong on both counts, I’m afraid. 1. The Schroeder crossover frequency is the transition frequency in large auditorium spaces, but not in small (domestic) spaces, where the Schroeder crossover frequency does not apply because it by definition is about diffuse spaces, which do not exist in small spaces. That is why, when you try to use the formula for Schroeder crossover frequency in a small space, you get very low numbers like 120 Hz, whereas that same room by simple examination of sweep response, you can see it transitions from mainly modal to mainly reflective at more like 300 Hz. The latter is the one you are talking about, but you keep calling it Schroeder frequency, instead of transition frequency. 2. Toole actually confirms all this, try pg 47 of first edition. Cheers

[@ErinsAudioCorner]

Erin - When you mention your listening levels like '80db', do you have your meter on "C" or 'flat' or 'A' weighting and do you use 'slow' or 'fast' response? Great reviews by the way!

[@ErinsAudioCorner]

Music, REW, no weighting, just looking at the spectrum an averaging the midrange area.

[@rammisframmis8588]

@@ErinsAudioCorner So on a sound pressure meter that would be roughly "A" weighting (mostly midrange responding) and "slow" response (REW's RTA function). I was mostly curious whether you include bass in the SPL measurement, as bass will increase the measured SPL in a flat measurement, yet not seem as 'loud' as if the SPLs were mostly in the area where the ear is most sensitive (midrange).

[@ErinsAudioCorner]

@@rammisframmis8588 correct. No, I don’t include bass because I test and review speakers of all sizes and I want to make sure the volume levels are reasonably close between tests. I’m looking in the 300-3000 Hz region.

The statistical average for a bookshelf is around 86dB. This is a hair above 83dB, so it needs almost 2x the wattage as your average bookshelf.

I happen to own a pair and fell in love with them instantly, so sweet. Run them with a simple Bluesound powernode (new generation) and a subwoofer. Simply gorgeous period.

If that’s how you feel then this channel simply isn’t for you as (nearly) everything I do is based on data and measurements. There’s plenty of others to choose from so no worries there. But FWIW, the manufacturer has seen the results and has not refuted them. Cheers!

Well, when Erin & JoeNTell reviewed the Neumi BS5P, their results were not what the designer intended and the company redid their crossover network & DSP to make the speaker better. You can probably count on your fingers how many audio companies own a decent sized anechoic chamber, and almost none of those give you accurate bass below say 100Hz, so you need the NFS or you splice it with ground plane measurements (KEF has stated they do ground-plane and said it’s a pain as they are in the UK where it rains a lot).

Baixo custo e altíssima qualidade sim senhor é muito bom mesmo espetacular incrível mesmo garantia absoluta certeza absoluta de altíssima qualidade

[@KravchenkoAudioPerth]

@@homeboi808 You don't need an anechoic chamber to get good measurements anymore than you "need" a Klippel system. What you need are decent tools and an ability to make useful measurements. Add to that the abilty understand what the measurements reveal. Erin does a great job of reporting what he has measured and relating it to what he hears.

I listen the music, no numbers !!

[@ErinsAudioCorner]

Cool. So do I.

[@lextr3110]

so should we assume mid crossover should be over 500hz

[@ErinsAudioCorner]

That’s more a function of midrange surface area and excursion. In this case, I’m not quite sure why the lower crossover point was chosen. But it doesn’t seem to be a huge detriment; at least not at moderate volumes.

[@lextr3110]

@@ErinsAudioCorner not sure but seem to me that a bigger low excursion 5-6inch flat cone coax and bigger tweet would make for better design at lower crossover point.. tho maybe would need supertweet for 10khz-20khz dispersion of the tweet.. maybe dome midrange low c2c with tweet is better design than small coax if higher crossover..
