They are pretty… and they offer a +2 dB treble terminal if you have a good room and want a little more detail.Those Hecos are about a thousand times better looking than the Revel M106s, too.

The HECO Celan Revolution 3 loudspeakers use a 30-mm tweeter according to the manufacturer's specifications. It's an interesting choice compared to the usual 19-mm or 25-mm dome tweeters that are often paired with a 6.5" driver.Crossover frequency of 2.8 kHz is on the higher end for a 6.5" cone / 1" dome speaker.
A review that contains some test measurements can be found here. The HECO specifications don't seem to specify any dB limits, just quoting a frequency range of 30 Hz to 52 kHz. That upper limit seems to be very high for a 30-mm tweeter. We could possibly assume that they represent –10dB limits. The measured vented-box tuning frequency appears to be at about 51 Hz or so, which seems more in keeping with the enclosure size and specified sensitivity.And I am incredulous as I read the specs. They claim 90 dB sensitivity yet 30 Hz on the low end.
And if the sensitivity really is 90 dB, they probably roll off soon and are meant to work with a sub.
IMO they’re pretty close to giant killers. I sold my Dynaudio Contour 20’s bc I flat out thought these were better in all facets above let’s say 50-60 hz. A different member here did the same, as well as his Special 40’s I believe. I made one of the most respected members of the Dynaudio forum on AVS order a pair to demo. He used to work for a high end store in San Fran and has some crazy gear. He was amazed what he was hearing. Totally understood why people could like the Celans more than C20 & S40, thought they were maybe the best speaker under 3500k, and said they were even with his Harbeth S400 SE’s which thoroughly surprised him.They look great and at a great price. Maybe @amirm will agree to do an express review if you send one in.
Regarding sensitivity— it has to be close to accurate, as they were the loudest speaker I heard at Audio Advice w/o any attempt at level matching.Crossover frequency of 2.8 kHz is on the higher end for a 6.5" cone / 1" dome speaker.

All I can say is their Fluktus tweeter design isn’t marketing gibberish. This 65 yr old company apparently knows what they’re doing. It may be 30mm but due to the design it’s as detailed/transparent as many metal-domed stuff and may even sound bright in a bad room. The Celans place me in say row 10 of 30, exactly where I personally want to be— lively, forward, detailed, and toe-tapping but not in your face. My Contour 20’s felt like maybe row 18-20. Celan makes C20 sound like it has a veil lifted. I had to notably bump up the Contour’s highs on my curve to get them to match the Celans. Actually, the Celans seem more like a slightly poorer man’s version of Heritage Special…. like, if Dynaudio made these and sold them as a special edition between S40 and Heritage Special, boosted the aesthetics a little & slapped on a $5k sticker, I would believe it.The HECO Celan Revolution 3 loudspeakers use a 30-mm tweeter according to the manufacturer's specifications.

The problem with taking the “livelier” demo speaker is that if it’s not presenting material in a neutral manner, it won’t sound great across all sources. It’s much better IMO to have a slightly “boring” speaker with good linearity/dispersion, that way you can adjust with tone controls if necessary to bring the fun back when it makes sense too. Otherwise, certain tracks just won’t sound right.I liked this speaker the first time I heard it, compared only vs M16…. but then when I demoed it at Audio Advice against Heco Celan Revolution 3’s [which I now own and love to death], the Celans made M106 sound boring. I guess I’m the type of person who gets in a car and can’t stand having EQ or tone controls set to 0 across the board and would rather have the presentation be a bit more fun, open, and lively but w/o losing refinement.
Not all of us want a neutral speaker that we have to EQ up to taste in a manner that may not be fitting of the original engineering of the speaker.The problem with taking the “livelier” demo speaker is that if it’s not presenting material in a neutral manner, it won’t sound great across all sources.

All well put. And I’m with you, for what it’s worth based on your explanation. If the Celans sound better to you in a wide range of content, then they’re the right speaker for you!Not all of us want a neutral speaker that we have to EQ up to taste in a manner that may not be fitting of the original engineering of the speaker.
For me there is no “bringing the fun back when it makes sense to”, as I would be bored to death with a speaker that spends the majority of its time in a neutral state. The M1016 would frequently remind me that they’re there, whereas my Celans completely & always disappear in my room.
For myself and others like me, I/we want a speaker that plays the way we want it to, in its natural state, and then for the rare times that we may want it more neutral or warm [which is never for me], we can tone it down if needed, but I have never needed to with the Celans. They play everything fantastically. To me, they’re just as comfortable in a tux as they are letting their hair down & rocking out. They kill it on jazz & blues, demanding female vocals, and also more energetic stuff like electronic & rock.
Now, I didn’t say livelier as in “showroom-fun speaker” like a B&W or Klipsch that soon becomes fatiguing in your home after longer sessions. They’re lively in the sense of being more enjoyably detailed, energetic, airy, forward, and toe-tapping but stopping before the point of reaching harshness. distortion, and imbalance. I’ve listened for hours straight w/ zero fatigue. They just impress me every time. I love hearing the micro details that I would if they were in the room w/ me— the subtle inflections & breathings of singers, cymbals that you hear the shimmy of, distinct separation of fervent drum beats, faint sound affects that are meant to be heard but are frequently missed… plus fantastic placement & separation of instruments across the stage, hearing the kick drum down low, vocals at standing height… and then the forward presentation providing wonderful & immersive 3D holographic imaging, with listeners convinced my side surrounds are on, as well as my front heights. Personally I’m not sacrificing any of that for a speaker that I have to spend time tuning to my preferences but w/o knowing how it’ll actual respond. Just their special paper-cone woofer alone was engineered to play & excel in the manner that they wanted the speaker to play, so it’s naturally faster, more agile, and livelier. Can you say a neutral speaker will respond the same way when asked to become something different?
There’s also the Celan’s low end that’s designed to be more punchy & present [which it is], so that’s another thing on the 106 I’d have to tweak, w/o knowing how it responds to the increased demands.
To me it’s like a Marantz receiver that’s already warmed the sound or Audyssey w/ Midrange Compensation on and us being unable to disable it— sure, you can try to EQ it to correct the issue, but that’s not the same result as not having the issue present in the first place. I’d place money that if I tried to make M106 sound like Celan Rev 3, it would fail. Heck, I tried to do it with my Dyn Contour 20’s which are closer in personality with the Esotar2 tweeter and still couldn’t accomplish it, as the C20’s were designed to be a certain way, and trying to make them something they were just didn’t work out. It reached the point where trying to pry that last bit of detail out of them to match the Celans, they began sounding unnatural and introduced some hard edges & sibilance.
So yeah, the Celans are everything I could ever ask for in a speaker while my budget is limited to under 3k. If that ever expands to 5k I’ll get their Belladonnas, even if the flagship stuff of other manufacturers were the same price.
Obviously to each his own though.
Like I said, the Celans are for people who prefer a more fun, forward, dynamic, holographic, toe-tapping, but still refined speaker and especially if it’s pulling double duty as HT mains where those traits make the experience more enjoyable/immersive. I thought my 7.2.4 Dynaudio HT sounded awesome… until I switched the entire thing over to Heco Celan & Heco Ambient 22F/44F, and now the Hecos make the old Dyn HT sound veiled, bland, and a touch lifeless. Now it’s a 9.2.13 w/ all Heco but that’s another story, lol.
One of the silliest ideas ever is neutral speakers are boring...I guess I don't understand the assertion that neutral speakers must be boring/unlively/clinical/etc. If a given speaker has audible deficiencies outside of its flat frequency response (poor bass extension / output is probably one of the bigger offenders, unless you have proper subwoofers to take care of that), then sure, it's certainly possible to ascribe such traits - but that's not the fault of its neutrality.
When using neutral speakers that are otherwise competent, lively material should sound perfectly lively, fun material should sound perfectly fun, etc. Potential acoustic issues with your room aside, they should simply sound transparent to the source. I similarly don't understand people who buy high-end displays and run them in "Dynamic" mode or similar. Is a football game boring because the grass isn't glowing as if it's been swimming in a radioactive spill? Or is your favorite show too "clinical" looking because the characters don't look like they got severe sunburns earlier in the day?
Sure, poor source material can be tweaked to taste, but we have things like EQ and tone controls for that. And starting with a neutral baseline with your speakers typically makes implementing those adjustments easier.
A member here did a home shootout of Ascend Sierra 2 RAAL, Revel Performa3, Focal Aria, Dynaudio Excite X18, and Dynaudio Emit M20. He found Emit M20 to be the most enjoyable, which didn’t surprise me the least. Since he liked Emit so much, I told him to find some Contour 20’s, use the Audyssey app to bump up their highs, and they would blow away that group. He did, and they did. He also bought Special 40’s, which he felt also whipped the group.It just sounds like too much. And no measurements yet. Could they really be just as good or better than Ascend or even Buchardt in the $1-2k range? Let me borrow them so I can compare to my S400 MKII's.
Silly to you maybe bc you like a neutral speaker.. but there’s a reason why not every manufacturer makes a neutral speaker and actually has sales from those speakers, and that’s bc not everyone enjoys a neutral speaker. I think I explained my own opinion perfectly well. There’s a reason why cars have tone controls or EQ. I find a neutral speaker to be more boring/bland/clinical, and I know others do as well.One of the silliest ideas ever is neutral speakers are boring...

There’s context & interpretation to this though. What actually IS “normal”?

Respectfully, I feel like I explained myself well as to why I prefer not do it the way you suggest. If Celan 3 [or insert other name] sounds brilliant to me as is, why would I take a risky, circuitous, more expensive, and more time-consuming route in attempt to achieve exactly what Celan 3 already provides me in its natural state?Sure, poor source material can be tweaked to taste, but we have things like EQ and tone controls for that. And starting with a neutral baseline with your speakers typically makes implementing those adjustments easier.
There is no debunking this and concerts have nothing to do with studio recordings. The point is that a loudspeaker is a playback device, just like a television. When calibrated to a standard, it outputs a signal as faithfully as its designers could get it to do without adding color or artifacts. That mostly means low distortion and a smooth and flat frequency response at all angles, with enough output to please.You and others claim “neutral” is how it should sound bc that’s how it was recorded. Well, respectfully, let me debunk that notion. Have you ever been to a concert?

So arrogant and condescending. So you’re suggesting there are few “critical listeners” among the abundance of people who buy speakers, expensive ones to boot, that don’t measure dead neutral? That’s one of the most absurd statements I’ve ever heard. You actually think people who own 2k, 5k, 10k, 50k speakers that aren’t neutral just randomly picked them out of a hat, never auditioned or went through a plethora of other speakers, other styles, on the journey that led them there, just a bunch a darn clueless idiots? I think you’ve been on ASR [emphasis on scientific measurements & neutrality] for so long that you forgot how the rest of the world operates and that people and especially peoples’ ears aren’t all the same.Because:
- Most people haven't heard one
- Most people aren't critical listeners and like the wow factor of a boom-tiss speaker for a song or two
Sorry, didn’t realize every neutral speaker sounds exactly the same as each other to begin with.[Sigh. I suppose we must have this tired conversation yet again, as if it is somehow novel, and completely derail a largely unrelated thread at the same time.]
Against my better judgement, I will bite on the last point. What you do not realize you are suggesting is a cycle of trading speakers in and out until brilliance is finally achieved, which is time consuming and expensive. Buying a neutral speaker with dispersion matched to your room and EQing it to your liking is a much more direct, and less expensive, path to achieving a setup that sounds "brilliant" to you.
If you want to have this discussion, please start a new thread and stop confusing this one with unrelated material.
Yes, a ton of them, but...huh? A live concert that you are attending is not a recording (well, I suppose lip synching is an exception...half a point awarded to you).There’s context & interpretation to this though. What actually IS “normal”? What is “sounding like it was meant to sound”?
You and others claim “neutral” is how it should sound bc that’s how it was recorded. Well, respectfully, let me debunk that notion. Have you ever been to a concert?
Live concerts, especially large amplified ones that involve a screaming audience, can often be acoustic messes (exceptions can more often be made for things like symphonic music in the better concert halls as well as small / intimate acoustic performances). You've just mentioned some reasons why they can be problematic. I don't attend them to be blown away by sound quality (the visceral impact of raw volume can be another matter), I attend them to see artists I like and admire in the flesh and often to have an enjoyable social experience with friends / family. I have very different goals around listening for enjoyment at home.I assume the answer is yes. No matter where anyone is sitting, are they all listening to the same concert? Obviously that’s a yes. If you’re sitting dead middle of the concert [call it neutral], is the sound being presented differently than if you’re a little closer to the stage? Obviously yes as well. Was the sound altered to give the change in presentation? We already answered that one- no. So, it’s exactly the same material, with no changes to it whatsoever, yet entirely different presentations based on where you’re sitting. Guess what, some people actually like to sit a little closer to the stage, some right up next to it, some relaxed in the back, and some right in the middle where the sound doesn’t venture to either end of the spectrum. I like to see a little closer to the stage.
I don't prefer boring musical experiences either live or at home, but thank you for the gesture.I won’t blame you for preferring that bland boring middle area.
There are quite literally thousands of song writers, vocalists, instrumentalists, recording engineers, mixing engineers, etc, who would strongly disagree with this statement.For all intents & purposes there’s no such thing as how a song was “intended to be played”.
For high quality program material, I want it to sound as close to the source recording as possible. What I don't want is for a rock drummer's repeating cymbal crashes to mask and smear the vocalist because my treble is shelved up and my mids are recessed. If the recording is bad or simply not to my tastes, I have options to adjust it via electronics. Swapping out speakers to accomplish similar seems quite cumbersome (not to mention expensive). Bad recordings can be bad in a variety of different ways from each other. No single set of speakers can account for and address all of these differences by themselves, particularly not passives.There’s only playing it the way you want it to sound.
If you're quite happy with your speakers then you should keep them. No one is suggesting otherwise.If you want to be a purist, have at it. If you want speakers that place you a little closer to or further from the stage, that’s your prerogative. I’d personally rather buy a speaker from a manufacturer that specializes at it than one that doesn’t and me being left having to tweak it, not even getting into stuff like preferences of soft dome over metal/ribbon/horn and vice versa.

They don't, which is why there is virtually no reason to assume that a neutral speaker must sound "boring" or "clinical" based only on the flatness of its frequency response.Sorry, didn’t realize every neutral speaker sounds exactly the same as each other to begin with.
