Excellent video and review of the Spirit Winds. I was fortunate to know Jeff and hear his original Spirit Winds. He was a great designer and even better friend. His contributions to the DIY community were incredible. I've shared your video with his widow and son.

Thanks for the very nice rewiew. We are happy to be a part of the project, by supplying the mid-woofers. You do Jeff great honor😊 Per Skaaning - Audiotechnology ApS Denmark

This is the Best Audiophile review video of the year. Cool runnings

You did an incredible job with the cabinet. It’s beautiful.

This is the most unique and best from you so far. There's not many reviewers out there that can do what you have done here. You assembled a DIY speaker and telling us how well it out performs REL subwoofer in the bass region..😍 and out performs KEF, Dynaudio speakers 😍😍..wow wow wow thats says something. I will definately put all my efforts in DIY this Spirit Wind. Thank you so much for bringing it to light.

Great speaker review, Srbo. Jeff Bagby was a great designer who made an enormous contribution to the DIY community. Props to Meniscus audio for an exceptional service as well!

Excellent video! Instead of simply reviewing something you help us experience it with you. What a gift...and what beautiful speakers!

Thanks , great to have the Spirit Winds finally reviewed. I thought they would be good and in all it depends on the quality of the materials and your room. I do want to build a pair of monitors but for now I have bought the Troels Gravesen " Revelator 851 " kit which I will build in January, not cheap at over 2,000 eurs but it will be worth it. Troels uses all Jantzen crossover parts, in the tweeter section it uses the Alumen Z cap , higher cost than in the Spirit Winds, The Tweeter is the Scan-speak D3004/660000 again more expensive. I really look forward to building them... Check him out if you haven't already done so, another great designer...Cheers.

WOW…What an incredible effort on your part to make the very best of a DIY Design! You deserve praise! 👍🏼

I am so happy you built a pair of DIY speakers! And especially from Denmark! I am currently assembling a Scanspeak 2.5 Way (Troels Gravesen) with Jantzen Alumen and Silver X-Overs. Cannot wait! That you mostly listened to the KEF LS50 in the past - which is a top & midrange-focused speaker made me a little worried that your reviews were seen through that "lens". Anyway, very happy that you are sharing the DIY options with the community 🎶🎶

Great review and a great build, Srbo. I have been lucky to listen to the Winds in two different systems in two different spaces. Although there were differences that even I could hear between those two systems, the common denominator is the wast soundstage, extraordinarily wide and deep. Great speakers, one of the best I have heard.

Well done. You have come a long way in your audio journey! :-)

Those look great, very thankful that Jeff made his designs public and shared them with the world. I built the Adelphos some 7-8 years ago, still have them, pretty good speakers, about a tie with my Kef LS50 overall I felt.

Great video. I really appreciate the passion and attention to detail. Looking forward to future comparisons with your new, reference speakers!

It's great that you made them. I have two different pairs of over 50 liter three-way floor standing speakers that are DIY. They are a pleasure to listen to because there is enough precision and authority. According to my information, there are many construction kits sold in various European countries, from which you can choose the one you like the most. Happy listening!

Definitely one of my Best Videos of the Year…Great Job!

I have made many speakers, this speaker was done so well. This is a 10,000 dollar speaker.

Great job! I recently used Rubio Monocoat for a speaker project, and I love the results. It's my go-to finish going forward.

Great video. RIP Jeff Bagby.

Very nice video! It is so intresting to see the crossover, the very high quality of the parts and how it relates to the performance of the speakers in all aspects, tonality, soundstage, dynamic impact, etc, etc. Bravo!

great video, great job on the cabinet. Very thorough review and analysis.

Those are beautiful and should sound fantastic. Great job!

Od mora videa o audio opremi na youtubeu koje sam tijekom godina pogledao, od testova komercijalne opreme do DIY rjesenja, ovo je daleko najbolji uradak koji sam pogledao i svako malo iznova pogledam bez konkretnog cilja ili namjere upustanja u ovako zahtijevan podhvat… sam nacin na koji je sadrzaj iznesen, na strucan i pitak nacin, do emocije kojom je opis prozet… gust je vidjet nekog tko nesebicno djeli svoje iskustvo i iskreno uziva u postignucu. Prekrasan zvucnik i cestitam.

I've been very interested in the Sprit Wind speakers and couldn't find a ton of reviews or much information about them. I was completely surprised that you had a whole detailed video about them, the only one on KZfaq!

THANKS 🤗 for sharing this story and all the details and credits of the contributors and your music 🎼 suggestions 🤗😎💚💚💚

Great review, and condolences to Mr. Bagby’s family And those speakers look amazing, I want them

The angled baffle with very low diffraction plus the high-quality crossover parts makes the world of difference, the reason I think the tweeter is performing so well. Happy holidays, Montreal Canada.

This is GREAT content! Love it!

Outstanding piece, and a great way to start Sunday morning. I use the 5 1/4” Arum Cantus drivers that are used in Bagby’s Continuum design, albeit in a different design and with crossovers a few levels below yours. Mine aren’t going anywhere, and I can imagine how great the Spirit’s must be with the component upgrades and a proven design.

A really interesting story and your fluent English continues to impress! Congratulations on your successful project 👍

Must be very satisfying to successfully complete such a project.

Great job. Many audiophile enthusiasts should learn from this experience.

Great stuff! Your build looks great - impossible to tell that it is not a commercial speakers. I have just finished my DIY projects and have very similar experience as yours - VERY satisfied that I have chosen this route. I was brave enough to make DIY preamp (Whayne Coulburne's - PASS Labs - WHAMMY); DIY FirstWatt F6 power amp (from Maestro Nelson Pass) and DIY loudspeakers - Troels Gravesen's Discovery 861 (ScanSpeak's drivers). Speakers and power amp have been finished less than two weeks ago. It was not easy, took me a while - about 4 years from first thoughts and completely no experience. Patience and willing to learn new things helped me a lot. It is difficult to describe how happy I am nowadays. Discovery 861 are great speakers. Pleasant, easy listening with full of details and deep, extremely controlled bass, crispy highs. Can listen for hours and hours, with no fatigue. Obviously, the rest of the system plays very important role, not only the speakers. Goddamn, that system provides so much details... just incredible. I spent about 1k euro for the speakers, but only ordered CNC cut of MDF, from my own drawings (damn, had to learn even AutoCAD basics...). A cheaper version of crossover was chosen, but components are very high quality - Superior Z caps for twitter (most critical place), Standard Z and CrossCaps for the rest. And they sound WONDERFUL. Check out Troel's projects: troelsgravesen - DOT- dk, great guy. So happy to find his projects. Form what I have heard, commercial speakers costs ~10-20% from it's retail price. Imagine what you can do, investing a few thousands $ into DIY speakers from a good designer... but you will get entry-level in high-end speakers if you buy new for that money. You should also consider DIY preamp, amp, DAC and even turntable. Last two are on my TO DO list =)

Inspiring review. I'm going to do it, even in Walnut finish!

Very good my friend and greetings from Brazil!

Wow, they are extremely high-end crossover parts! I’m a DIY guy, a kind of, a sort of, and I’m using Janzen Superior Z-cap. It’s good enough for me, and I have to satisfy with this. Silver Z-cap is a dream. Good for you.

Wow. This video is magnificent. I really enjoy your reviews. Thank you!

Love the flat smooth response; they look great! I want!

Thanks for the nice video! You're right about the subwoofer. The minimum REL for your speakers is the S/510. By your description of the sound performance, that speaker is like my Dynaudio Heritage Specials - a speaker that you basically cannot point anything bad about it except it's actual size (and price for the Dynaudio's). It takes a marginally big, fast and detailed sub to match it, but once you match you won't take it out. Two even better :)

Awesome channel! You provide lots of information and knowledge. Willing to share with others 👍. Unlike some other channels such as Thabhamar, Thomas and Stereo, Jay Iyagi, yada yada yada... They talk nothing except how expensive the gear they are testing. It's like they are so pricey and they must be good. Thank you Srbo.

DIY done right, gives SO much back to the music and the pleasure of building them and then say, I build these and they sound awesome! Correct me if you can! No one want to compare….

Jeff Bagby was the best!

Awesome review as always! I have been playing with the idea on and off with going with DIY speakers. There are some good values in audio DIY out there. I have heard some glowing reviews of various brands and models but they are never as articulate and detailed as yours. I am going to take a deeper look into these and research some local wood workers for the cabs.

It’s a very beautiful looking speaker. I have the LS50 with the REL T7X. I can relate to what you describe 👍👍👍👍👍

Excellent and well detailed discussion. thank you.

Well done. Excellent project

Great video, thanks. I want a pair of these so much!😅

Being able to control the expense applied to crossover components, as in, spending big on quality crossover components, can be the most rewarding aspect of DIY'ing. This is an area where commercial manufacturers, inevitable, boost their margins. It would be interesting comparing against an identical build but with 'standard' crossover components. (I'm using Mundof MCap Supreme EVOs and a variety of bypass caps, in my Open Baffle DIYs.)

congratulation to this fine project. I agree quallity parts in the cross over is verry important. I have build famos ARA Kit from SB Accoustics with satori drivers and also upgrates Quallity in the X over. i think i have the same impression of soundquallity as You when listening.

Love your works and the review. I need to DYI a speaker too :)

Great job, all around!

Those are beautiful!

Great job, they look Beautiful with the American walnut!

Great review! I have never heard of these diy speakers so it’s really appreciated, as I plan on building speakers in the future. I’d be interested to see all the components you’ve found that pair well with them. I use the Dynaudio Focus XD 200s, and like that darker tone as well. Cheers!

Very inspiring. I currently vote you as number 1 internet reviewer because you look at things with a technical and musical perspective neither pointless budget nor stupidly expensive. Most reviewers use clickbait constantly running between the latest and imagined best until 2 days later there is something better - they are audiophile bimbos. Your English is much better than you credit yourself with and your word choice is much better than the extravagant meaningless sentences employed by most others. For the moment I will be looking into the following four - Kef L50 meta, Kef R3 meta, Focal Aria 906 and Amphion Argon 3S but I think your build is likely to satisfy my needs better. I ,live in France and it is not easy to find a physical shop. Can you tell me how big the sweet spot is for your Spirit Winds build both vertically and horizontally - they are important to me because I like to be mobile and I think you answered my other questions. If I can find what I want from my 4 auditions I will stop there otherwise I will hunt down the plans for yours!

Thx for the video! very interesting. How do you treat the copper (binding posts) to not oxidise?

Great job!!

Re tweeter difference, it's the high quality crossover parts that tamed the 2905-9900. Can't go wrong with that, with top quality parts. Congratulations iiWi!

Congratulations!

Hi enjoy your reviews very much ,do you think its worth getting musician pegasus dac for the hegel h190 thank you very much

wow great to see a pair of Spirit Winds made after jeff bagby passed away R.I.P. I'm sure they are just about as high end as you can get with those two drivers

Hi! Very nice video and speakers, indeed. What about the sensitivity of those? Do you think they are power hungry? Thanks

Great review! Thank You. Are there cabinet and crossover plans that are available on the internet that you can share?

This is my favorite IIWI review. How is late night listening on this speaker? What is the lowest volume (decibels) you enjoy listening to these speakers?

Nice Review!!!, any plans to review the Chord or Holo Audio DACs, more interested in the Holo Spring as it is said to blur the difference between D/S and R2R DACs and is bit on the affordable side too, comparatively off course 🙂

Thank you for this excellent video. It was very helpful in many aspects for me. One that was missing was the comparison to other speakers. I totally agree that comparison to commercial speakers is not in place. Why not compare them to similar price DIY speakers ? for example from CSS audio or GR research...

Hello Srbo I follow and enjoy all your reviews. I have built many diy speakers over the years starting with transmission lines and folded horns. It’s surprising to many how much effect box design and composition along with crossover parts quality can have on the outcome…even with the same speaker components. I particularly was surprised by the positive effect of wire gauge in air core inductors. Can you please post the source for your copper connectors? Best Regards.

Even though this video was long, I watched every second. I love this design. I have a few pair of speakers and have been considering the DIY. This looks like a winner. I love the cabinet design. I like the fact the BOM is super high quality. I may be doing this soon. Ill watch this again. But quick question, the box was this part of there design or you? I do not recall if you mentioned that part. Anyway keep this up, you are getting way better. Happy Holidays JJ

very cool, love your speakers. Next, you have to try dedicated 10awg wire circuits to each component. or at minimum 1x 10awg circuit for the amp, 1x 10awg circuit for the rest. It made a big difference in my system!

Love that you have used threaded inserts to mount the drivers instead of the usual thing of just screws into the wood, which is found on even high end designs and annoys me whenever I see it. The cost of a few threaded inserts cannot be much and it stops any possibility of chewing up the wood which is all too easy with just plain screws. That walnut veneer is very nice too, they look classy.

I would love to know how these compare with the musician knight 1 regarding sound quality.

Is it possible to list the components used for the crossover and speaker taps so I could reproduce what you have built? I see they offer upgraded caps but not to the level you have assembled. BTW thank you, excellent video! Seems the MoFi SourcePoint 10 maybe inspired from these.

Looks similar to the Musician Audio Knight 1 Loudspeaker. Wondering if they are the same design. Sonically, it sounds similar to the cheaper CSS 1TDX kit that I have in my system.

Great review! I feel sad that I sold my drivers now.

Awesome! This is a new territory for you my friend. Making your own speakers are great and they have some personal attachment as well. But I wonder will these be your main / primary speakers for a substantial amount of time? I guess, only time can tell.

For me, I had about €1000 to spend on speakers last year. It just wasn't enough budget for really good DIY speakers, I couldn't find good value kits in Europe. I slightly regret not saving up more money and hope to build these in the future. However my wharfedale Evo 4.3s that I got cheap aren't too bad really. P.S Jantzen make probably the best cost to quality ratio components available. Apart from capacitors, I got some of their large binding posts recently for my DIY amplifier. They cost €6 each, top quality, look like they came from a premium luxury amp.

Great video, the cabinets look similar shape to new mofi Andrew Jones design speakers

OMG..That's the way to usher in the new year. 👍👍 You mentioned in the review that you added some -------- filing inside ? I couldn't hear it. Thanks in advance

Great review. What is the minimum distance, according to you, to the front wall to still have a wide and deep soundstage?

I made a 300$/pair bookshelf and they really play outside of their league... With a -3dB at 35hz, they are very good without a subwoofer.

Great job with this project. I recently got plans from Meniscus Audio and like you I'm also sourcing the drivers from Europe to save on shipping costs. i came accross different versions of the AT18H5217 driver (8, 6 and 4 ohm). Which one did you use in your project or does not matter? the plans dont mention anything about it. Thanks

Try the KC62; great little sub 👍👍 good review, thanks

Vrlo lepo umjetnicko delo, da bi ih samo slisao!!! Shapo.

What an amazing review! I'm also in the market for a new speaker, and now I'm considering making my own. Seems a tiny bit scary though, do you think anyone could do it with enough patience and research? I don't have friends like you that are into DIY speakers.

Meniscus Audio has closed, would you share the plans so I can give it a try? And links for (buying the parts)

Thanks for making this video and speakers🙏 I am still under the impression that speakers fill the room better with subwoofer, if not REL would you try pairing it with any other woofer? Cause they can't dive under 40hz, can they?

Thanks! Please try to review more speakers! "Spirit Wind" sound like a Totem name!

Perhaps the time has come for this particular conversation to start with the MiniDSP Flex. Certainly it's an attractive idea and you don't have to trust some else's design. Lot to learn though.

looks beautiful...wished these DIY companies can offer a finished option

If you do not know the cabinet is directly taken from the Avalon speakers, with the way the front is cut. Nothing wrong with that, but just Think the credit shall go where Jeff obviously have been inspired from. Have 2 models of Them myself. The old model Arcus and one from the new Line, the Idea. Both excellent speakers with no obvious faults. Very revealing and no fatigue whatsoever🙌🤗 Looks nice with the cabinetwork🙌

Very well presented video! I, myself have relied on DIY speaker building projects to get the most "bang for your buck"! I have built 7 speaker pairs using the best components (Dynaudio, Scanspeak, Accuton, Mundorf (Silver/Oil) Caps, Hoviland Caps, etc.) to achieve the highest sound quality. This is the best way to pay for the tools and components to ensure the fun and $$ to build for yourself the BEST audio speakers possible! My questions to you: 1.) Did you have to "break in" your new speakers to delvelope its neutral response? 2.) And, if you did, how many hrs. did you allow? 3.) How important is it to use a quality amp, or can a vintage amp do (marantz, Luxman, or even a Denon 7:1 surround sound integrated receiver? Thank you for your time.

Sorry. Wanted to find out the brand of crossover component you mentioned. Yinseng?? Thanks.

Given that Meniscus has closed down here in the US not long after you posted this video, do you know how I can get access to the cabinet dimensions and design, and also the crossover design? Seems that if I knew who to contact, I could make a contribution to the family, and get a copy. Have you communicated at all with Seth Horton who worked with Jeff on this design?

Sorry for keeping you busy with such details, what does Dacron Panel helps for?

Great review, you can take a look at YB Audio, based in Poland they offer similar technology and prices 👍

Thanks!

I wonder how good this speakers are compared to Dynaudio Contour 20i. Excellent review!

Thank you so much for this amazing review. I see that meniscus provided you the dimensions for you to source your own cabinet. Is there an option to buy the cabinet online?

Pozdrav! Sve čestitke na kanalu, prava rijetkost na našim prostorima! Kako je moguće da su dijelovi koštali oko 2000 e kada na stranici set bez kabineta kosta 2000? Da li moguća Vaša pomoć da se napravi ovakav zvucnik?

Great review and outcome for your diy project build. Your channel has a very interesting collection of equipment and intelligent reviews. You have a great talent for explaining sound. You have also found opportunity; Build Spirit Wing design quality speakers. Start a business, employ your fellow Serbs. God speed. Cheers from the US.
