Thanks for the great review and your insights + updates to the speaker. I was eyeing this speaker and was curious what people are saying about it. Now I want to get it even more thanks to your review.

[@2ChannelListening]

Glad it was helpful, thank you for watching.

[@khoi83]

I just finished listening to the whole review. Really good and very informative as usual. Bravo to you and to Heco. Well done!

Thank you for putting up with 30 minutes of me, my wife commends you! 😄👍

[@khoi83]

I know that for many listeners 30 minutes are very long and your style may appear boring to them but it's perfect for me. Many flashy reviewers stay at a subjective and at the surface only but you take the time to carefully Listen, even to tweak the speaker and to recommend us very honestly with your own experience and in depth and details. Bravo. Take care.

[@pickyaudiophile]

Thank you for that in-depth & tear-down review of the Hecos! How wrong I was about the screws. That was improved, compared to the "Direkt Dreiklang" speakers I used to own few years ago. BTW Hopefully you, your family, friends, pets, home and lastly your precious HiFi gear will never ever be affected by a tornado impacting your area. Even though when you released that "new home" series of clips and I heard 'Oklahoma City' I instantly thought about elevated tornado risk right there in the pathway of "tornado alley", I mean elevated compared to your previous place of residence. - But I understand there might be more weighty benefits than pondering too much about tornado statistics and it's always a matter of pros and cons when moving. Thank you for your service to the HiFi community, it's appreciated!

[@2ChannelListening]

I really appreciate your generous compliment, thank you sir. I am probably going to shoot my foot now; the light weight of the Sonetto I really bothers me. For the right price, I would consider trying the Sonetto II, but again, my experience with really light modern speakers means big cabinet compromises like this here Heco. The doors not shut, it's just not top of my growing list. Thank you for watching the entire review! Hope to have you back for future reviews.

[@todddavid9101]

Those of us who’ve actually listened to the Celans in HT applications would heavily disagree about how they perform in HT, especially when in an appropriately sized room for them and when they’re run as Small and crossed at 60 or 80 Hz. This is pure silliness to suggest they’ll fall apart in an HT setting. At -15dB (70 master volume) they are clean & composed. Low distortion. Secondly, few of us should be buying these (or any bookshelf for that matter) with the intention of playing music with peaks in the mid 90’s. With my Denon 6700 master volume at 70 I get an average level of 80.9 dB with peaks of 87.0 dB, and that’s LOUD. That’s like me trying to turn my HT into a club… and yet the Celans still performed beautifully at that level. Thirdly, HECO uses Klippel testing to make their speakers, and the exuberant charm of the Celan lies in how fun, vibrant, energetic, and slightly lively they are. As soon as you stuff them (like you did) you slightly deaden the sound (like you experienced) which effectively diminishes what makes the Celans so fun & fantastic to begin with... and so now it’s no longer a Celan. You just dumbed them down for the majority of us who aren’t going to be listening at ear-bleeding levels. If you want a speaker to damage your ears with, buy something else; if you listen at normal levels or don’t need to crank your bookshelfs to reach sufficient SPL, then get the Celans. I had a full 7.2.4 Dynaudio HT with Contour 20’s & 25c for LCR [which ARE braced & stuffed], along with Dyn Excites for sides & rears which later became Emit M20’s.. and switching to the Celans for LCR and Ambients for surrounds made my HT come to life. There’s even more detail extracted now and a slightly more forward airy engaging sound, without introducing any unwanted distortion. It’s extremely clean & crisp with MV at 70 [-15dB] on my Denon 6700. Intelligibility is superb.

[@2ChannelListening]

Hi Todd, disagreement is perfectly fine here. Glad you love your Celans. Thank you for giving sufficient backstory on how you use and enjoy your Celan . I still own mine and enjoy them how I like to listen to them. Thanks for watching.

[@todddavid9101]

Cheers mate. Love the content and in-depth reviews. A bunch of us across a few forums have gotten the Celans for HT, and the feedback has universally been fantastic. They’ve won every single shootout I know of from a dozen or so ppl on AVS and ASR. I just wish Heco or Audio Advice [whomever is responsible] would bring the Celan Rev 7’s to the US!… and also the insanity known as Belladonna!

[@2ChannelListening]

Hearty YES to the Belladonna...

Great review like always, I wonder if you used No Res. damping material and did not use any of the poly fill. I would think you would achieve superior damping with out losing to low level sonics.

[@2ChannelListening]

The great thing about the lambs wool is it can be adjusted, remove some, add some. I like the tighter bass it has at higher SPL's this way, it is a compromise for sure. Thanks GT.

[@ekiquantameki7701]

I have had revolition3 for 3 years. I bought it by accident because my Klipsch RP home theater 5.1.2 set did not sound good in stereo. After hearing heco celan, I replaced the klipsch with Heco Revolution7&rev4. We did not know the prices so great. It plays well with Yamaha as2200 and revolution3&rev7

[@2ChannelListening]

Sounds like you stumbled on to serious enjoyment!

[@video-en6ws]

Hi, great review, many thanks. I bought a couple of these HECOs (used). In my opinion, they lack the openness, airiness and space at the top, as many describe them. The treble lacks air and space at the top, even compared to the Elac DBR62. Maybe because the inner walls of my pair of the loudspeakers are covered with a layer of damping material, such as cotton wool. As far as I know, the walls of the speakers are not covered with anything inside from the factory.

[@mhester99]

Just got a pair and they have what looks to be wool stuffing on the bottom and rear panels in addition to the white poly panels on sides and top

[@2ChannelListening]

Someone added that then, no way would any of these mass produced speakers come with wool or polyfill at this price point. At least I have yet to see one. One up for you.

[@press227live]

Dear friend! Thank you for the high-quality review of my favorite speaker systems, which I also call night speakers. I want to give sensible advice on upgrading any cases. This is a big misconception when amateurs distribute cotton wool or other sound absorber evenly throughout the entire body. The best results are obtained by a relatively dense ball of the simplest cotton wool, wrapped in gauze. It is recommended to place it approximately in the center of the body. I read this advice on the forum of professional designer Alexander Klyachin. The bass from such an upgrade becomes dense, clear, punch is felt, but the amount of bass does not decrease. When we scatter cotton wool over the body, the bass reflex does not work well, the meaning of its existence is lost. With all respect, Andrew!

[@mcjonner]

For the celons can you compare to philharmonic bmrs? I would LOOVE for the celon 7's to come here, they would be an instant classic i think

[@leo11877]

Wondering if couple of dowels would be a good replacement for the car audio dampening material.

[@2ChannelListening]

I thought about that as well, but I didn't want to start down the road of making bracing, not right now. It is something which could be added as is though.

[@mikedinno8413]

How do they compare to the Ascend Acoustics Sierra you reviewed a while back?

[@2ChannelListening]

The Heco are much fuller with a distinct playfulness that reminds me of what I love about ZU Audio. Hands down the bass hits harder with more texture versus the 2EX. The 2EX has a higher build quality, yet the would be my preferred dance partner at this price.

[@kurtfisher8608]

I watched all three vids mostly for information on the V8B. I've been a big Aperion fan for years having owned many different models. (Still own several, including a full 5.1 Verus Grand HT setup) I've wanted a pair of the V8B's for two channel in my office environment for some time now. Watching the review by Erin's Audio Corner caused a pause, as he really emphasized a few troubling measurements ending with a less than favorable review. Did you test the V8B's on tubes or solid state gear?

[@2ChannelListening]

Hello Kurt, Erin's report is interesting however his comments do not jive with my experience. Interesting, if those comments were directed at the MA Silver 7G, I would have completely agreed. Where I found the Intimus T to exhibit unpleasant peaks and inconsistency, I thought the V8B performed very well and consistent. I used all manner of amps, SS class D, hybrid and tube. Provided my room is smaller and treated, so maybe this mitigates some of his findings while listening. Erin's reporting on bass performance absolutely lines up with what I was reporting, super clean and full of detail. Funny how many folks want their speakers to perform like Revel and Perlisten on paper, yet I talk to all the folks who trade in their Revel's and Perlistens because they are tired of them, they crave something more musical. Its a well built speaker, way better than its foreign competitors at $1500 range. I do not like tilted or lit up speakers so maybe this is why the V8B appeal to me more. You never know if you never try.

[@kurtfisher8608]

@@2ChannelListening ...and try I did! I snagged a pair used believe it or not, for a steal. I'm close to Aperion in Oregon so fortunate to find them on the used market often. (And I know what to look for having years of experience with them) They're fabulous! After trying many amps I settled on my Vincent SV 237 as best, and what a pairing! I do like a little sparkle on the top end so ended up using tone controls to boost treble a tad, and the resulting sound stage is impressive! Speakers totally disappear with a refined center image. Love them! Only problem is that I also have a set of Solstice DIY speakers with upgraded SB Acoustics Beryllium tweeters & Mogami wiring, and they're better. I've gone back and forth many times, and the Solstice towers are just better. (Amazing...really) It's hard to decide between the two as the build quality and finish on the V8B's is so gorgeous....

[@roybrolsbeak]

I have the focal aria 906.. bought after reading all the great reviews. Im not happy, the highs feels harsh and i see myself turning the volume down. Would you say the dali rubicon or ma silver 100 7g would be better. Any demo recommendations? Thanks for your help sir

[@2ChannelListening]

I do not recommend Monitor Audio Silver 100 7G specifically for the inconsistencies I heard, some sharp, forward tendencies. Not sure what country you are in, try Philharmonic BMR, Dynaudio Evoke 20, Dali Rubicon 2, Opera Prima.

[@roybrolsbeak]

@@2ChannelListening thanks for getting back to me; i have my eyes set on the celan revo 3. would you say its up there with the evoke 20 / rubicon ?

[@2ChannelListening]

@@roybrolsbeak I think for the price point, I couldn't find a better performing speaker with so much character and performance. The Rubicon 2 is a more refined, better built speaker, yet the Revo 3 has deeper, punchier bass. One for the other and you save $1800! The money you pay for the Rubicon is incredible quality control and non of the mess I opened up in my Revo 3 to fix with missing glue seams.

[@psyphonyxaudio]

Nice looking bookshelf.

[@2ChannelListening]

Yes they are indeed.

[@psyphonyxaudio]

@2 Channel Listening ... I'd like a Sonetto 1 if I wanted a curved wedge cabinet. (Arguably better sound too)

[@nc3419]

I have a short list of speakers I may consider going forward, waiting until I move and know what my environment and needs will be. Right now its an apartment. For an overall general purpose standmount speaker have looked at Dali Rubicon 2, the LSA signature 80 someone else mentioned in a response, and perhaps Musician Knight 1 at $2K, if only it had a nice wood veneer. There may be a few others as well in a small option. Would prefer a wood veneer but definitely avoiding gloss black. If I wanted to go bonkers, there's the Totem Fire but well see. Right now, for low level listening, my budget options are doing pretty well within their abilities.

[@2ChannelListening]

Honestly when you start talking about Totem Fire kind of money - you might as well have Jim Salk build you a pair of Philharmonic BMR's in the veneer of your choice, $2,500 and its better than the Rubicon 2, as much as I like the Dali.

[@nc3419]

@2 Channel Listening I'll keep that in mind. I do prefer a smaller footprint but if things change, the bmr still is manageable. Thanks.

[@legrandgroves8560]

I do have a pair of LSA 80, LSA 50, and BMR, so far the BMR philharmonics are the best but how does it compare to the Hecos?

[@2ChannelListening]

@@legrandgroves8560 the Heco's and BMR's would be a terrific match up for sure. The thing about the BMR's, with a Jim Salk hardwood cabinet, you are getting a better product that will ultimately showcase greater refinement and a bit more details, the BMR a tad quicker on pace. Tonally would come down to preference of driver mixture.

[@joecharpentier6636]

I owned the Heco when it use to be sold at Audio Advice. I liked it quite a bit. Had it connected to a Nuprime Ida 8 integrated amplifier. Great combo. THEN......I got ahold of a basically brand new pair of the Aperions. HOLY MOLY WOW!! Night and day difference. Smokes the Heco with every aspect. Maybe the Heco can compete in the Highs. But everything else has the Aperions tanking the Hecos. I did put some $$ into the Aperions as far as some no rez and a friend did up the crossover with very expensive sonic caps etc. That upgrade set me back $300 per speaker. He knows more than me about that aspect. Now it competes with my Canton References. Probably better. And those cost me $5k. But bone stock it blows the Hecos out of the water

I really loved this review. I wanted to get these Heco speakers. I am cool with some DIY work, no biggie. I have Elac Unif Reference UBR62 & I am not happy with the bass output. Plus, I really miss the natural tone of a paper mid-bass/bass driver!

[@2ChannelListening]

I'm really digging these speakers for their flexibility and efficiency. They shouldn't sound this good with a little 50 watt desktop amp from Fosi. I have them cranking out Mediterranean acoustic like nobody's business. I bought some different damping matts to play around with cabinet fill and extra layers, remove a bit of the lambs wool. If I had a real work studio with miter saw and materials, I would play with adding bracing. The drivers are worth the coaxing efforts.

[@x-techgaming]

So what is the top 5 ranking so far? Philharmonic Bookshelf is #1?

[@2ChannelListening]

Interesting, the resale value of the BMR V2 is holding very high now that Jim Salk is out of the speaker making business. There are a limited number of BMR's out there so it is not exactly a used bargain the way the Heco Celan 3 is. I'm seeing Totem Element Fire V1's in the mid to low $2K range, that's a better used buy. If you can get a BMR for under $1400, then yes, top of the list.

[@NemoPropaganda]

@@2ChannelListening oh okay, that's not that crazy then, I thought you were doing A weighted. Sorry for all the questions man, just want to try and replicate this to see if its an issue across the range or just maybe the pair you got because these speakers so far are a contender for product of the year and I wanna make sure theres no issues before I start recommending them left & right.

[@NemoPropaganda]

Alrighty so I just pushed these damn things HARD and pushed them well north of 95dB, I'm talking 105-110dB spikes, C weighted, subwoofers off, using a variation of songs like Put On by Jeezy, Set Me on Fire by Pendulum, Cherish by Madonna, Smooth Criminal by Michael Jackson, and Name by Goo Goo Dolls, oh and Alquimia by Different Heaven. These things held their composure all the way up, not a single cabinet vibration, hell I couldn't even feel anything when I put my hands on the cabinet. Last I changed to A weighted and pushed them to 100dB and the results were the same. I don't know if your pair are different but the ones I have are built like a tank. My room is similar just slightly bigger at 12x14 with 9ft ceilings and all measurements were from the listening position using a physical dB meter and cowitnessed with a second cheaper dB meter. Anyway, if you bought that pair I'd suggest having them replaced under warranty or consider the possibility that something else could be amiss? A loose binding post, room interactions, etc... who knows. I remember one time being absolutely convinced a speaker was blown only to realize I had left the binding post loose lol but yeah, could also just be a bunk set, anyways, just sharing, have a blessed day!

[@savagemako17]

It's heavy for it's size, so I figured most of that weight was in the cabinet. They're are selling at a ridiculously low price right now. Could this be the reason why? I have heard nothing but good words about this speaker. The only real negative that people reported was a very long break in period. To bad, I love the looks.

[@2ChannelListening]

The weight is in the amazingly large magnets for both drivers. There is no bracing and nearly no damping material. I didn't find them to have a long break in period, they sounded pretty good right away save for the cabinet issues of my pair.

[@St4vKa]

I think you took the Celans from a correctly dampened cabinet to an over dampened one, sacrificing bass performance and probably some other characteristics as well. Personally I wouldn't touch a speaker in any way, as I would just be destroying the work of the speaker designers. Heco does use the Klippel laser system to measure it's products, which among others can measure even the smallest distortions generated by the cabinet.

[@2ChannelListening]

I have to go by what my ears hear and the Heco in stock form could not keep up with the other two speakers when pushed. I removed a lot of the wool and substituted with 1/2" damping pads over 50% of the surfaces, nice balance now. Tone with better breakup control. Thanks for watching and commenting.

[@mhester99]

Mine have wool on bottom and back areas. The white poly on sides and top

[@kenhiett5266]

I disagree vehemently. Resonance and distortion at volume is easily discernible, and that's a lack of quality to hit a price point.

[@St4vKa]

@@kenhiett5266 I have these speakers now, my usual listening levels are around 85 dB max and I wouldn’t go above that since it would be unbearable, there’s no distortion that I could discern with my ears, all I want to do is to keep listening to these speakers. I have pushed them above 90 dB on a few cases just to see how they would fare and again there was no distortion that I could discern, that took my attention from the music or made the sound unpleasant in any way. There’s also another reviewer that pushed the exact same speaker above 100 dB and didn’t hear anything either. I’m not disregarding 2ChannelListening’s opinion but in his case there could be a defective pair, bad amp/speaker combo and even the room since it plays a huge role on perceived quality and can introduce distortions on it’s own. These Celans are a fantastic pair of speakers and easily unbeatable in the 1000$ range imo.

[@DiabolikLegend]

Hi there! The German speaker brands have a strange way of measuring frequency response. They list at +-12db so you can't compare to other speakers.

[@frankd.b.9233]

So 4 mistakes that I know and see now to make them better thanks

[@NeilBlanchard]

Yikes - 3 metal core inductors? And 2 of them in the same orientation? The 3rd one is in the same orientation as one of the small air core inductors? The curved sides does stiffen the cabinet, all else being equal, but obviously the cabinet is a weak point. I would suggest the 3-layer foam that Parts Express sells - it won't effectively reduce the interior volume of the cabinet as much as the foil faced material, and it is quite effective at damping the panels.

[@2ChannelListening]

Given the European price point, the crossover parts quality will be the first shortcut. The drivers are pretty darn good in my opinion.

[@NeilBlanchard]

@@2ChannelListening They do look well designed and well made. The 5 coils in the crossover mean they are probably using 4th order on both drivers, and there is a notch filter (probably) on the woofer. That is a fairly complex thing to build. In my most recent speakers, the MLTL-6 Tower, I am using a series crossover that has 3rd order slopes - there are only 2 coils and 2 caps and 2 resistors (used in parallel for power dissipation). The coils total only 0.78mH. so I can afford 14AWG air core Solen units, and with 2 bypass caps on the ClarityCaps - the parts total about $160, I think? That's retail - but the quality is much higher than the Heco, too.

30hz - 50khz may be 'accurate' but at what Db? +/- 18db or 12db or 6db? Frequency response specs must always include the Db range for it to be meaningful. The usual standard followed by many reputable speaker companies is +/- 3db. Some do it +/- 6db. Those that do not quote that part of the spec are trying to mislead consumers who may not know better.

[@2ChannelListening]

I've noticed Canton and Heco do this with most of their speaker line. Post an exceptionally broad frequency response and yet no indication of at what +/- db range. Certainly will trick folks into thinking the bookshelf speakers handle full range. Marketing by omission.

[@ekiquantameki7701]

yesterday I listened to bw805d4 with Marantz pm10 in the store. I will not write that Heco is better, it's more that the bw805 had bad acoustics. Or maybe I don't like the sharp sounding loudspeakers made by the earlier Klipsch. Heco at home sounded more musical for me.

[@2ChannelListening]

I can see why Heco is so popular in EU. I have not heard the latest Marantz amps, so I cannot comment how they wound with B&W.

[@ekiquantameki7701]

@@2ChannelListening Marantz pm10 is the flagship model of this company, maybe it's the fault of a bad connection bw805d4 I read that these are great speakers. Heco is at interesting prices, I don't know about you. Personally, I play Revolution7 & revolution3 with Yamaha as2200 and denon pma2020, Rotel ra1572. The latest Yamaha is the best. Greetings from Europe

[@ekiquantameki7701]

In my country, Poland, the new Heco Celan Revolution3 in the store 800euro after talking to the seller. I bought a brown used 6-month old for 420euro. And for 2000euro I bought a new black Revolution7. They have no problem playing quietly like Revolution3. Regards.

[@ekiquantameki7701]

great speakers. Even at prices after Covid. I have a whole home cinema set. Revolution 3, 4, 7 Svs prime Elevation 2x svs sb2000. Revolution7 need power, that's why with the Onkyo rz1100 I attach the power amplifier Yamaha as2200 l & Denon pma2020. Yamaha plays great with Heco in stereo.

[@2ChannelListening]

@@ekiquantameki7701 wonderful, thank you for sharing from Poland. Enjoy your Heco.

[@reestyfarts]

Those 30K+ hertz tweeters are alleged to be resonance dampers.

[@2ChannelListening]

Sure is doing nothing for the sidewalls.

[@williamsmith9194]

Before you got just a little in explaining..I was thinking that you know specs

[@hoobsgroove]

No I wouldn't use that dampening material and why does everybody get the stuff with the foil it's not necessary; you can get it without foil. What is it about 8 mm thick you going to lose volume of the cabinet, a better solution would be to use a roof repair water-based rubber solution without fibres. just brush it on but it is permanent that's what I use very good..! you want the exact one I can give it to you. Another benefit would be to make a blu tack bead for the drivers, 6mm for the woofer and 3,mm for the tweeter this will be best for cutting out sound resonance especially from the woofer. I would take the wool from the sides you can leave it at the bottom and just put it on the back right level with the port you don't need it on the sides. And with that damping material it doesn't really work so well as a painted on water-based rubber solution, use water-based not solvent because that could affect the glue in the drivers!! And is not pleasant to work with. What concerns me there is no side bracing between the sidewalls and the front baffle as you can see it is being machined at a slope that must be very thin at that point?? really you need a corner bracing all the way top to bottom without touching top and bottom, otherwise it can cause buzzing.

[@2ChannelListening]

The foil exists because you have no way of applying it without 80% of it being stuck to you...I'm also guessing, but the foil help keep the venting down, nasty stuff. The Heco drivers are pretty inert, but it wouldn't hurt to put some resonance material on them as you say. Nice suggestions HG. There's an Open box out there for $900 - looks like a good experiment for another brave soul...

[@hoobsgroove]

@@2ChannelListening I didn't say put the roof repair sealant on the drivers but I suppose you could cover the basket, you can do the driver this has to be diluted by a third and only on the edge of the driver cone no more than 10% from its surround, to dampen resonance from the driver. I meant paint the inside of the cabinet with it..!! as a dampening material. They are bitumen pads what you put on you can get them without the foil well used to anyway, the only reason they have the foil for cars is to keep heat in or blocking heat in the summer getting in, same principle as insulation for your house. Another thing I noticed is the port is too short to produce those frequencies talk about, what it could benefit from is a much longer port and two together 2" apart between them, will give better set up and against the wall as well. I would extend the port three times its length and be slightly bigger or better used two or one and a half?? where the half would be a ½ inch pipe half the length of the main tube, prevents chaffing and better airflow. Try it you can always cut a piece of wood and fill it up and painted over nobody we'll see it. but if you do that on the length of the port at the moment you've got?? you will need to extend its length to double the length of the main port. just get some plastic water pipe tubing make a big difference. But really you want to extend the main tube to get the benefit of the low frequencies in conjunction. You could experiment by sliding another tube over the existing one! Like a gutter down pipe, wrapping tape around the original port and sliding on a tube with a fairly to tight fit. have a piece of ¼-½ inch dowel going through the end of the pipe, ¼;an inch from its end should be fine, this helps with less chaffing problems as well, on the end of the tube pipe connect piece of string to the dowel through to the outside of the cabinet, extend as I say the tube at least.. three of its standard port tubing length, and slowly pulled tube backwards in 3 mm increments, you can mark this beforehand on the extended tube by engraving and paint over with white paint what you can see from the outside! and listen to the speaker. If you need to push the port further out you can use a piece of wood against the dowel, make sure you glue the dowel in with epoxy resin glue like gorilla glue, just do one speaker at a time don't listen to both together, and give yourself time 2 weeks on one speaker listening adjusting you might need to repeat this process. Of course placement will play a part so find the ideal placement for yourself this can be against the wall or further out when adjusting, and make sure you keep it at that spot for the ultimate tuning, of course it will still work in other areas say further out into the room but won't be at its optimal so much. If you want the speaker to be further from the wall then set it up at 3.4 ft wall behind and 3.8 from the sidewall. The port tuning an extension is all reversible so no issue! Just make sure the tape is even and probably the whole length of the original port in your case and is a fairly tight fit. Give it a go you got nothing to lose.

[@2ChannelListening]

In a way, that is the Totem approach. Very thin layer of Borosilicate damping product applied to the interior cabinet. Sure doesn't look like much...

[@chuckmaddison2924]

Originally i believe they were a cheap DIY kit in Germany.

[@user-cs6fk4ok2o]

Всем привет! Кто слушал новые Heco In Vita 3??

[@legrandgroves8560]

BMR Philharmonics still #1

[@2ChannelListening]

For the price point, it would be BMR, ZU DW, or Ryan R610. For $1,500 though, the Aperion Audio V8B is no joke. I played them again the other day after $3,300 Totem's and couldn't help but smile.

[@khoi83]

Oups like 1$ worth of damping material...

Probably close
