Great review Steve. I very nearly went for these but have decided to wait for the Buchardt E50's. Hopefully I have made the right decision and you will get to review these at some point too.
Another thorough review of a product that, in the end, made you "happy." To me that's key, your system should make you happy. If you're not feelin' it, my advice is keep watching this guy, he's got a lot of it figured out already and enjoys surprises.
I listened to them a few weeks ago. They are very good and insane for the price. Loved the clear sound but I thought the bass was a bit dry. Maybe a Hegel could force the bass in to compliance. Can't wait for a floor stander.
Love that DALI and Lyngdorf made this together. The 6.2 cost a little less than the Dali Epicon 2, would like to see a comparison between them. And then a comparison with the brand new Dali Epikore 3.

Interesting that you're reviewing these while I am looking seriously at getting Buchardt Audio's new e50 speakers. Both Danish made. Both around the same price. Both with purifi woofers and very similar frequency specs. Very different cabinets, however, as the e50s are solid oak with a waveguide for the tweeter carved into the wood. Both sold direct to consumer with shipping and taxes included. Buchardt's free trial period is a little longer at 45 days. I'm wondering if a pair is on your way? One other thing. Both of these speakers seem very hard to drive with low sensitivity and a 4 ohm load. Yet you didn't seem to have any trouble with your relatively low-powered amplification
It really grates me that Buchardt make such a big deal of their 'free worldwide shipping, taxes included' which is not actually correct as the whole of Africa and many countries are actually excluded from this.

Steve, I love my DW6's, buuuuuut, you got me interested. I wonder what the dimensions of the "small" and of your room are. I'm oriented long-wise in a room that is 15' x 28' with my Zus and a Rel classic 98 hooked to my Unison Research Triode 25 Integrated Amp.
Steve, thanks for all the great work you do! You mentioned the clarity, dynamics, resolution these speakers have but any comments on the quality of the tone they produce?
I am interested in that as well, especially when trying to reproduce low frequencies. Passive radiators get into some curious phase issues down near resonance and below, which partly results in a sharper cut-off.
Graet review snd seems as great soeaker which im considering. Would love you compare this one to PS audio FR5. And please .... also at close to wall position. ( 4"). 🎉
I want to go check out the 1969 CSNY release. One of my favorite recordings is Side 1 on the Grateful Dead’s Bears Choice. Also recorded in 1969 (or maybe early 1970) at the Filmore East. Bear Stanley was the audio engineer and I feel like he captured the scale of the room perfectly (despite me never having been there).
Really good review. In terms of expectations. The radiants are something that I would build, except for the proprietary AMT Tweeter. Think Troels 6R w PR instead of port. Love that you compared them to the Zu even though the Zu is 1/2 the price. (It seems that some other reviewers don't give the Zu any love these days.) Also loved how you compared the amp pairings.
@@razisn The design isn't all that new. Look at Troel's Purifi 6R. The wave guide and AMT Tweeter for the Radiant is proprietary but there are other wave guides and Tweeter options. In terms of 'sandwich' of materials to make the cabinet... not really an issue. I was thinking if money was no object... Richlite since Panzerholtz is too expensive to get in US. There are also YT videos on certain epoxies that have some sonic properties as well. In terms of CNC also not out of the realm. There are maker spaces that have multiple CNC plus laser cutting too. Also not sure that I would follow their cabinet design. There are other options.
@@michaelsegel8758 So you wouldn't really build this speaker.. Different tweeter and different cabinet construction = a completely different speaker. Plus, if you really tried to copy the cabinet, one-off CNC job and all, it would probably cost you much more than buying the speaker..
@@razisn You would build something similar as best as you can. Its not that you want to copy it, but the point was to build out the Troels Purify-6R but using the two 6.5" PRs. Since you're using different Tweeters the passive XO would be different. Cabinet size would be roughly the same size and volume would be the same or similar based on the Purifi driver and your cabinet tuning. See Purifi's docs on size and how much weight to add to the PRs.
More good work by the domesticated Vikings. Balance is so important. My Cabasse Murano speakers sound best with Belles mono amps and a Rogue RP5 hybrid tube preamp where I can slip in Mullards, Wathens, or PSVane tubes to tailor the sound and mitigate some of the hyper clarity of the Muranos. Everything in its own lane.
Nice to see you that enthusiastic! I'm very curious, if you have any chance of comparing it with a boenicke w5, wich is about the same price, and has the same effect that, it sounds way bigger then the size of the speaker. Thanks for the nice review.
These speakers sounds pretty good, with a wide soundstage but lacks a bit on the deep soundstage and instrument placement. Futhermore it lacks a bit wildness and authentication in the vocals, both male and female. Last but not least i think it could be a better sounding speaker by using higher quality crossover parts, instead of those cheap caps and resistors, but it is still much better quality compared to most other speakers in the price range. Overall a great product that deserves a high quality amplifier to make them shine.
You would probably need a great Tube preamp with this speaker to be able to listen to a wide range of music. You should look into the Revival Atalante speakers some time. I think they are not on the American market yet, but they look and sound great and punch above their price point.
The price point is out of my consideration. I trust your review..and it looks like it is a solid construction. And they guarantee is marvelous. What would we do without Steve Guttenberg you always deliver on point review..its greatly appreciated. Keep up the great work !!!!!
It should be interesting how this compares to the new Buchardt E50 when it comes out. Similar woofer from Purify, different tweeter and passive radiator setup.
Everything about the Radiant tech is well conceived but I'm tired of black and walnut boxes. The Danes are known for furniture design but this is painfully generic.
The audiofile ppl dont want to go to far away from the origins, somehow they think speakers and medium do not evolve. What kind of speaker are you looking for? Exept boxy boxes or open baffel?
@@ivodepievo9481 I deleted my first reply to you. Why be boorish to the boorish? Yes I did pay attention. The black speaker looks like a desk top printer and the white speaker looks like a air dehumidifier. At $4500 I expect a little bit of design.
@ indeed no need to be rude, and no need to compare these speakers to other appliances.. who cares what you think of them.. it’s okay to not like them and you don’t have to but there are a lot of people that put lots of time and energy in creating a product they feel proud of and your critique doesn’t bring anything to the table..
Nice shirt, and a lovely review! After having listened to these myself I agree with you on every point. The room placement can dramatically alter the bass response, and they are quite power hungry. These speakers can benefit a lot from room correction, which I did using RoomPerfect from the Lyngdorf TDAI 1120. The imaging and spaciousness of these speakers is just out of this world!
when does this end... when will speaker design/engineering come to an end? My 4 way upper mid hi fi 2007 jbl speakers are supper hifi compared to speakers in the 80's and early 90's? I have centre image and soundstage.. what more can a person want.
It comes to an end for each person to decide when they're satisfied. I'm happy you are, but other people are still looking for the right one. And you keep coming back watching videos, for me that's all that matters. Thanks so much!
@@SteveGuttenbergAudiophiliac Steve, you are the last few joys in music. I love watching your videos as it gives me something to think about... Have a wonderful weekend.
. ............when magnets & coils are no longer used as the driver motor. There will be digitally controlled actuators & monitoring sensors moving the driver cones. Virtually zero distortion & un-blowable. Acid Jazz, Funk & Brass 🔈🔉🔊
. PS.. I think the only reason it's not done now is because there aren't any 20KHz actuators. However aren't class D Purify modules over 20HKHz? Aren't they electro-mechanical? Acid Jazz, Funk & Brass 🔈🔉🔊
the zu dirty weekend is an objectively crap speaker, please see the measurements and fundamental design flaws by watching gr research and maybe erins audio corner's video on them. they're trash.
Those woofers look like the surround is vinyl caulking applied by a five year old. Sorry, but for $4,500 I'd want something that sounds AND looks good, and the choices at that price point are vast. I will stick to my Zu Audio DW6 which are way more affordable and sound great.
This the Purify driver special surround to allow very long throw to the drivers. It is what it is, if it weren't like this it wouldn't work like that..
@@razisn If that's the case Steve should have shown it in action, but he didn't even mention the weird design of the surround. Does any other speaker have that feature?
@@chrislj2890 The funky surrounds address position-dependent effective area deviation, ... which generates distortion. In essence, the inward stroke increases cone size, the outward stroke decreases size. Plus, distortion causing bell modes are diminished by the ring design. These Purifi woofers are absolutely state of the art, low distortion, high linear output drivers. iirc, they range from 4" to 10" The surround is only one drive unit element that's been optimized. Funky aesthetics or not, no drivers possess the capability that these Purifi possess. About a decade ago a handful of the brightest audio veterans joined forces and created Purifi. They revolutionized Class D amplification. They're revolutionizing small woofer design as well. edit, fwiw, Steve's discussed these woofers in previous videos.
@@chrislj2890Buchardt uses them in the Anniversary 10 active speaker and the yet to be released E50. There are a few others. These are expensive drivers. Most manufacturers won’t use them for that fact. Most people who hear them are impressed how they can play loud, deep, and accurate with lower distortion than other speakers of similar size. The crazy folded surround is partly why. One possible drawback is lower sensitivity
You have to remember that making this stuff in Denmark, where they pay a living wage is expensive. There's no way around that. And they are low production designs, which also makes them expensive. Of course if you have a better idea, how to make something like that for a fraction of the price, go for it!
Probably not, the crossover frequency will be to high for an eight inch woofer. It may play out to 2500 hertz just fine , but the eight driver will certainly have a narrower off axis frequency response well before the the crossover point. That will mess up the sound stage and imaging qualities that were described in this review. It really would need a midrange driver to achieve the same characteristics. That being said: it would give the designer an option to raise the crossover frequency of the midrange and tweeter . That could be a simpler crossover. Likewise the same could probably done at a lower crossover frequency for the woofer to mid-range. Certainly a wider baffle will also play into the design considerations too along with a larger cabinet. On other words it would be a totally different speaker. It would also be significantly more expensive in the end. These with good bass management and a subwoofer or two will certainly get the low end extension into the 25 hertz range and still be less expensive with no change in the sound stage. Another benefit with a sub and limiting the bottom end for these would also show up as the volume knob goes up and they aren't working so hard in the deep bass region trying to extend the bottom end past what they are capable of. This would be an easy sub set up because the sub crossover could be fairly low, but just high enough to take a load off the 165 mm bass driver in these.
Indeed, many good points. It's worth noting that the Achilles Heel of these folded ribbon AMT platforms is the modest extension in the lower range of the HF driver. AMT drive units beam, and oftentimes don't extend as low in freq as other driver platforms. - Beaming is addressed via the waveguide. - The limited range of the AMT is addressed via the 6.5" woofer's size. So, increasing the LF driver size up to 8" can certainly facilitate 50% more LF capability. However, the additional piston diameter initiates beaming ~23% lower in freq. Thus, necessitating a redesign of the HF waveguide.
@@D1N02 My second comment was to a very insulting reply of his calling me what can be described as an orifice opening in the backside of humans or animals for which 'we' have no need for more. That comment was either deleted by him or. most probably, by the YT filtering algorithm filtering on particular words... So, now you know... Sometimes things are not what they appear to be. Look elsewhere next time you want to try to be clever.
They're very cool and all, but $4400? I guess maybe if you MUST have bookshelf speakers and you have a lot of money. I just can't believe these are a better bang for buck than some towers on the market.
Not sure I understand the comparisons, other than they are just what you had on hand? Both comparison speakers cost half of the Radiant Clarity. Price is not always a tell for quality, but still this seems like an unfair comparison.
Hey, I have no choice but to use only the speakers I have on hand. It is hugely unfair to expect other speaker companies to spend possibly hundreds of dollars for shipping to me and back for their speakers, just for a comparison. That's not the way this review business works.
@ Fair enough. Just curious, are those two sets of speakers your “go to’s”, meaning regardless of what you get in, you just really enjoy having the Zu’s and Buchardt’s around to listen to? If so, I find it really interesting. The Zu’s especially have been “panned” by certain other TH-camrs, but specs aren’t everything. I bought a pair of speakers positively reviewed by many YTer’s, but I really thought they were “meh” in my environment. It is one of those things that makes this hobby interesting and occasionally very entertaining!😄
As a general rule, any design which aims for particularly exceptional performance in one or two categories, in this case clarity and deep tight bass, will of necessity perform to a notably less degree in one or more other categories. Nature doesn't offer hyper-realism. Example; 8k TVs VS the 4k resolving ability of the human eye. "There are no 'solutions'... only trade-offs." Thomas Sowell

@@geoffreydebrito7934 I'm waiting for you to answer my question. Otherwise your original comment is worthless, since you seem not to really know what you're talking about.
Who cares? Do you go after each review that reviews something you can't afford or is beyond your budget and make this comment? What makes you think anyone but you is interested in your budget?
The comparisons are rather disappointing, you need to stay with within the character family, studio monitors, Genelecs etc. otherwise you are too far off target and its just an other meaningless rant. PS Sensitivity: 85 dB @ 2,83 is terrible, you failed to disclose that.
This is not a studio monitor. You seem confused. Why would you think comparing it to an active, DSP'd ugly studio monitor designed for near-field use, would be more appropriate beats me. Sensitivity is as it would be expected to be for a small passive speaker with very good bass extension. Higher sensitivity would mean either less bass or larger size.. Physics is physics. Do you buy hifi equipment based solely on reviews without looking at the specs yourself? Specs are on their website for everyone to peruse, I don't need Steve or any one else to recite them for me, I'm not that lazy.
@@keplermission Well I can drive my 85db ProAc speakers with my 25wpc Musical Fidelity A1 very fine thank you. So can I with my 230wpc amp. Tell me again what exactly is misleading. Any modern hifi amp apart from flee-watt SETs will drive a 85db stand mount speaker up to the level it is designed to go. Plus, power is cheap, we don't live in the first half of the 20th century anymore if you haven't noticed? Plus, nobody would buy these speakers to drive them with a cheap current deficient anaemic AVR..
Can We (you?) give us a example of a similar speaker with same soundstage, clarity, depth, size and quality, then I’m all in for a review. For me the Buchardt seems closest.
@@keplermission I asked Rocker6969, what he would choose instead. What is better? I myself live 10km from the closest Hifi klubben (Sweden) so I can audit in the shop.

Steve, I love my DW6's, buuuuuut, you got me interested. I wonder what the dimensions of the "small" and of your room are. I'm oriented long-wise in a room that is 15' x 28' with my Zus and a Rel classic 98 hooked to my Unison Research Triode 25 Integrated Amp.
I'd say your room is too large for the 6.2s and most small speakers.
I dig the shirt Steve!
I have a few videos on these in my space. My sound demos did not go so well ..but in the room .. they are very compelling.
Steve, thanks for all the great work you do! You mentioned the clarity, dynamics, resolution these speakers have but any comments on the quality of the tone they produce?
I am interested in that as well, especially when trying to reproduce low frequencies. Passive radiators get into some curious phase issues down near resonance and below, which partly results in a sharper cut-off.
Graet review snd seems as great soeaker which im considering. Would love you compare this one to PS audio FR5. And please .... also at close to wall position. ( 4").
🎉
He won't. He stated he won't replying to another comment here..
I want to go check out the 1969 CSNY release. One of my favorite recordings is Side 1 on the Grateful Dead’s Bears Choice. Also recorded in 1969 (or maybe early 1970) at the Filmore East. Bear Stanley was the audio engineer and I feel like he captured the scale of the room perfectly (despite me never having been there).
Thanks Drew! The live CSNY he's good, but not a lot of sound of the theater space.
That shirt, man...wow! 😍
Really good review.
In terms of expectations. The radiants are something that I would build, except for the proprietary AMT Tweeter. Think Troels 6R w PR instead of port.
Love that you compared them to the Zu even though the Zu is 1/2 the price.
(It seems that some other reviewers don't give the Zu any love these days.)
Also loved how you compared the amp pairings.
Thanks Michael!
I'd like to see you DiYing the sandwich construction and the CNC'd front baffle.
@@razisn
The design isn't all that new. Look at Troel's Purifi 6R. The wave guide and AMT Tweeter for the Radiant is proprietary but there are other wave guides and Tweeter options.
In terms of 'sandwich' of materials to make the cabinet... not really an issue. I was thinking if money was no object... Richlite
since Panzerholtz is too expensive to get in US. There are also YT videos on certain epoxies that have some sonic properties as well.
In terms of CNC also not out of the realm. There are maker spaces that have multiple CNC plus laser cutting too.
Also not sure that I would follow their cabinet design. There are other options.
@@michaelsegel8758 So you wouldn't really build this speaker.. Different tweeter and different cabinet construction = a completely different speaker. Plus, if you really tried to copy the cabinet, one-off CNC job and all, it would probably cost you much more than buying the speaker..
@@razisn
You would build something similar as best as you can.
Its not that you want to copy it, but the point was to build out the Troels Purify-6R but using the two 6.5" PRs.
Since you're using different Tweeters the passive XO would be different. Cabinet size would be roughly the same size and volume would be the same or similar based on the Purifi driver and your cabinet tuning. See Purifi's docs on size and how much weight to add to the PRs.
More good work by the domesticated Vikings. Balance is so important. My Cabasse Murano speakers sound best with Belles mono amps and a Rogue RP5 hybrid tube preamp where I can slip in Mullards, Wathens, or PSVane tubes to tailor the sound and mitigate some of the hyper clarity of the Muranos. Everything in its own lane.
Belles best kept secret
Wow, 'everything in its own lane!'
looks like they set back the amt to correct phase.could be why the clarity is so good.
Great review. Wonder how it would compare to Platimon and FR5?
Nice review, Sir!
Your shirt resembles a jockey's uniform. ;)
Nice to see you that enthusiastic!
I'm very curious, if you have any chance of comparing it with a boenicke w5, wich is about the same price, and has the same effect that, it sounds way bigger then the size of the speaker.
Thanks for the nice review.
These speakers sounds pretty good, with a wide soundstage but lacks a bit on the deep soundstage and instrument placement. Futhermore it lacks a bit wildness and authentication in the vocals, both male and female. Last but not least i think it could be a better sounding speaker by using higher quality crossover parts, instead of those cheap caps and resistors, but it is still much better quality compared to most other speakers in the price range.
Overall a great product that deserves a high quality amplifier to make them shine.
You would probably need a great Tube preamp with this speaker to be able to listen to a wide range of music. You should look into the Revival Atalante speakers some time. I think they are not on the American market yet, but they look and sound great and punch above their price point.
Looks like Stevie Wonder installed those woofers.
And we wonder why
@@khoi83 Stevie Wonder was blind.
My ,, wonder,, was a wordplay
How does the clarity six point two compare to cabasse murano.
The price point is out of my consideration. I trust your review..and it looks like it is a solid construction. And they guarantee is marvelous. What would we do without Steve Guttenberg you always deliver on point review..its greatly appreciated. Keep up the great work !!!!!
Same woofers as in the recent Buchardt models, right?
Same brand of woofer, Purifi, they make a lot of different models. Purifi sells those woofers to consumers, check out their website.
It should be interesting how this compares to the new Buchardt E50 when it comes out. Similar woofer from Purify, different tweeter and passive radiator setup.
Everything about the Radiant tech is well conceived but I'm tired of black and walnut boxes. The Danes are known for furniture design but this is painfully generic.
The audiofile ppl dont want to go to far away from the origins, somehow they think speakers and medium do not evolve. What kind of speaker are you looking for? Exept boxy boxes or open baffel?
They come in white and other finishes…. Didn’t you pay attention?
@@ivodepievo9481 I deleted my first reply to you. Why be boorish to the boorish? Yes I did pay attention. The black speaker looks like a desk top printer and the white speaker looks like a air dehumidifier. At $4500 I expect a little bit of design.
@ indeed no need to be rude, and no need to compare these speakers to other appliances.. who cares what you think of them.. it’s okay to not like them and you don’t have to but there are a lot of people that put lots of time and energy in creating a product they feel proud of and your critique doesn’t bring anything to the table..
@@ivodepievo9481 I care.
How does it compare to the cabasse rialto speakers in terms of sound clarity and bass extension ?
I have a pair of Klipsch Forte IV: Is it worth changing them for these?
No, not if you're happy with the Klipsch sound.
Not the sound I’m chasing but nice review.
What about the Zu Union Supreme 6? These cost about the same as the Radiant Clarity 6.2.
Nice shirt, and a lovely review! After having listened to these myself I agree with you on every point. The room placement can dramatically alter the bass response, and they are quite power hungry. These speakers can benefit a lot from room correction, which I did using RoomPerfect from the Lyngdorf TDAI 1120. The imaging and spaciousness of these speakers is just out of this world!
Those woofer and radiator surrounds are wild looking. They look damaged
That IS the way they look, on purpose!
Pleated surround to allow very long throw with minimal weight.
@@SteveGuttenbergAudiophiliac lol…bring back fabric surrounds
Absolutely each and every speaker manufacturer in history has claimed deep bass extension and low distortion in his designs...
Your point being?
thats why there are measurements…
@@larsrisbo2293 Which prove that these speakers do what they are claimed to do.
@@razisn exactly! (I am an insider)
No. Deep bass and extension was a 1970s thing before that, well ... long story.
when does this end... when will speaker design/engineering come to an end? My 4 way upper mid hi fi 2007 jbl speakers are supper hifi compared to speakers in the 80's and early 90's? I have centre image and soundstage.. what more can a person want.
It comes to an end for each person to decide when they're satisfied. I'm happy you are, but other people are still looking for the right one. And you keep coming back watching videos, for me that's all that matters. Thanks so much!
@@SteveGuttenbergAudiophiliac Steve, you are the last few joys in music. I love watching your videos as it gives me something to think about... Have a wonderful weekend.

There's already readily available inexpensive drivers with essentially ideal playback capability.
Good Day Steve. Cool, nice, but IMO not for $4,500. I'll go bigger thank you.
the zu dirty weekend is an objectively crap speaker, please see the measurements and fundamental design flaws by watching gr research and maybe erins audio corner's video on them. they're trash.
I could find no Erin's video on any Zu speaker.
@razisn just gr research then, I wasn't sure. His review is sufficient to say it's crap.
Those woofers look like the surround is vinyl caulking applied by a five year old. Sorry, but for $4,500 I'd want something that sounds AND looks good, and the choices at that price point are vast. I will stick to my Zu Audio DW6 which are way more affordable and sound great.
This the Purify driver special surround to allow very long throw to the drivers. It is what it is, if it weren't like this it wouldn't work like that..
@@razisn
If that's the case Steve should have shown it in action, but he didn't even mention the weird design of the surround. Does any other speaker have that feature?
@@chrislj2890
The funky surrounds address position-dependent effective area deviation, ... which generates distortion.
In essence, the inward stroke increases cone size, the outward stroke decreases size.
Plus, distortion causing bell modes are diminished by the ring design.
These Purifi woofers are absolutely state of the art, low distortion, high linear output drivers.
iirc, they range from 4" to 10"
The surround is only one drive unit element that's been optimized.
Funky aesthetics or not, no drivers possess the capability that these Purifi possess.
About a decade ago a handful of the brightest audio veterans joined forces and created Purifi.
They revolutionized Class D amplification.
They're revolutionizing small woofer design as well.
edit, fwiw, Steve's discussed these woofers in previous videos.
@@chrislj2890Buchardt uses them in the Anniversary 10 active speaker and the yet to be released E50. There are a few others. These are expensive drivers. Most manufacturers won’t use them for that fact. Most people who hear them are impressed how they can play loud, deep, and accurate with lower distortion than other speakers of similar size. The crazy folded surround is partly why. One possible drawback is lower sensitivity
@@thewaygokid3135
Thanks for the info!
If they pay the importation taxes, they would go bankrupt selling to Brazil. I doubt their profit margin can survive 92% taxes.
Steve I would love you to review the Qualio IQ Ultra speakers from Poland. I'm very interested in those! Cheers!
they sell direct, Steve has no business connection with the Qualio Audio guys. Sorry, it's all business.
@mediascapes2011 You might just have a point!
Irrespective of the R&D, i wonder how much parts cost is?
You have to remember that making this stuff in Denmark, where they pay a living wage is expensive. There's no way around that. And they are low production designs, which also makes them expensive. Of course if you have a better idea, how to make something like that for a fraction of the price, go for it!
How does it compare to a B&W 805D?
Why is everyone talking about price we're not buying it. It's interesting.
Thank you! I doubt people are doing the same when they look at Ferrari reviews, reviews are not buyers guides, they are for entertainment purposes.
@SteveGuttenbergAudiophiliac yeah really
This speaker with 8” drivers would be even better.
It would be a completely different speaker in all respects, physical and acoustical..
Probably not, the crossover frequency will be to high for an eight inch woofer. It may play out to 2500 hertz just fine , but the eight driver will certainly have a narrower off axis frequency response well before the the crossover point. That will mess up the sound stage and imaging qualities that were described in this review. It really would need a midrange driver to achieve the same characteristics. That being said: it would give the designer an option to raise the crossover frequency of the midrange and tweeter . That could be a simpler crossover. Likewise the same could probably done at a lower crossover frequency for the woofer to mid-range. Certainly a wider baffle will also play into the design considerations too along with a larger cabinet. On other words it would be a totally different speaker. It would also be significantly more expensive in the end.
These with good bass management and a subwoofer or two will certainly get the low end extension into the 25 hertz range and still be less expensive with no change in the sound stage. Another benefit with a sub and limiting the bottom end for these would also show up as the volume knob goes up and they aren't working so hard in the deep bass region trying to extend the bottom end past what they are capable of. This would be an easy sub set up because the sub crossover could be fairly low, but just high enough to take a load off the 165 mm bass driver in these.
@@stevengagnon4777maybe they should do it with the coming Purifi tweeter then? 🤩🤩
Indeed, many good points.
It's worth noting that the Achilles Heel of these folded ribbon AMT platforms is the modest extension in the lower range of the HF driver.
AMT drive units beam, and oftentimes don't extend as low in freq as other driver platforms.
- Beaming is addressed via the waveguide.
- The limited range of the AMT is addressed via the 6.5" woofer's size.
So, increasing the LF driver size up to 8" can certainly facilitate 50% more LF capability.
However, the additional piston diameter initiates beaming ~23% lower in freq. Thus, necessitating a redesign of the HF waveguide.
8 inch has more bass but loses middle frequency dispersion and power.
I spy a Dynaco PAS preamp!
Amazing... but at $4500, a bit out of reach for me...

They're very cool and all, but $4400? I guess maybe if you MUST have bookshelf speakers and you have a lot of money. I just can't believe these are a better bang for buck than some towers on the market.

Not sure I understand the comparisons, other than they are just what you had on hand? Both comparison speakers cost half of the Radiant Clarity. Price is not always a tell for quality, but still this seems like an unfair comparison.
Hey, I have no choice but to use only the speakers I have on hand. It is hugely unfair to expect other speaker companies to spend possibly hundreds of dollars for shipping to me and back for their speakers, just for a comparison. That's not the way this review business works.
@ Fair enough. Just curious, are those two sets of speakers your “go to’s”, meaning regardless of what you get in, you just really enjoy having the Zu’s and Buchardt’s around to listen to? If so, I find it really interesting. The Zu’s especially have been “panned” by certain other TH-camrs, but specs aren’t everything. I bought a pair of speakers positively reviewed by many YTer’s, but I really thought they were “meh” in my environment. It is one of those things that makes this hobby interesting and occasionally very entertaining!😄
Your shirts are something to admire as stand-alone of your gigs!😮
I don’t know Steve, at that price my expectations would be pretty high.
As a general rule, any design which aims for particularly exceptional performance in one or two categories, in this case clarity and deep tight bass, will of necessity perform to a notably less degree in one or more other categories. Nature doesn't offer hyper-realism.
Example; 8k TVs VS the 4k resolving ability of the human eye.

So which categories do you think this speaker performs to 'a notably less degree'? Please enlighten us further.

You will be disappointed in your life..
The comparisons are rather disappointing, you need to stay with within the character family, studio monitors, Genelecs etc. otherwise you are too far off target and its just an other meaningless rant. PS Sensitivity: 85 dB @ 2,83 is terrible, you failed to disclose that.
This is not a studio monitor. You seem confused. Why would you think comparing it to an active, DSP'd ugly studio monitor designed for near-field use, would be more appropriate beats me. Sensitivity is as it would be expected to be for a small passive speaker with very good bass extension. Higher sensitivity would mean either less bass or larger size.. Physics is physics. Do you buy hifi equipment based solely on reviews without looking at the specs yourself? Specs are on their website for everyone to peruse, I don't need Steve or any one else to recite them for me, I'm not that lazy.
@@razisn Well specs are misleading. Sensitivity 85dB needs an amplifier designed to cope.
