Inspiring build! I have been looking at various transmission line speaker designs to build. I like this design. Very beautiful. At 60 years old I already have some missing frequencies in my hearing, and after about 14KHZ, I can't really hear anything, so I am not sure I could fully appreciate their performance. Regardless, I like building things. I used to have a pair of JBL 4412s. I wish I still had them...
Found this video while searching for horn enclosure builds, but then I saw your workbench! I have the same saw, and I want to be able to cut sheet goods, so I think I'm going to copy your design.
Excellent work and a very cool project. I did something similar with the Fostex FE103NV 4.5" Full Range FE103NV drivers and a much smaller enclosure. Sounded so different than a "regular" speaker. Mid tones are amazingly clear and top end gently rolls off. Lower end needs a bit of an omph, bt a subwoofer took care of it.
Cool design, but it seems like a TON of work. I built 3Pi horns from Pi speakers (94dB eff) and am very happy with them. Just a braced, ported cabinet. Unfortunately, they need a subwoofer, but I suspect these do too.
Сейчас есть масса dsp, которые позволяют обойтись без сжигания мощности усилителя на кроссовере, и максимально сгладить ачх. Жалко, что вы их не используете..
Outstanding craftsmanship with quality hardware. The speakers look amazing. I was thanking of building something along these lines, but was hesitant as I've never had the opportunity to listen to a pair to see how they sound. Is the music at the start and end from these? Thanks for the vid.
Nice project... I almost build a pair of BD Oris horns loaded with Lowther - the cost of shipping the horns from the Netherlands was more than shipping a human ( return trip ) to Sydney - which made me pause the project, as I just could not "stomach" the shipping fee.... A few years later i had an opportunity to audition them in Sydney..... The beaming & directionality that I heard, made them unlistenable to me - as much as transient response & "immediacy" & low level detail in the midrange were on par with the best electrostatics.... These TB drivers have nearly doubled in price over the last couple of years... Have you got experience with the Seas FR drivers & how they compare to these ?
Hello Cool Dad.😊 Greetings from a newbee.... Great project. I have the fostex fe166 en drivers . There are plans avabile on the homepage off the driver.. how ever I want a more sleek design ( less boxie but still having the same volumen) .... therefore: are You aware off a expainer off " how to" use the software for dimensions off horn speakers... ? From a to z . B.r Christian Fabricius from Copenhagen...
Hi! Awesome work on the speaker! I actually want to learn how to does sound work, how are speakers built, how do you improve sound quality of speakers. Is there any book you could suggest. Something that would at least help me get started? Thanks!
If you ever read this, please tell me why you needed to use a crossover when you are only using a single driver? Also, what is the advantage of a folded horn compared to a Voigt tube? Thanks.
The frequency response is rarely linear some frequencies are high like in this case the midrange is a bit higher and needs to be tamed down a bit to sound better.
Well made loudspeakers. Thanks for sharing your knowledge and plans - I'm going to build them too. Please let me know what model of microphone you used during the measurements?
That final frequency response looks very flat indeed, an excellent job all round. Are you familiar with the Joseph Crowe audio channel ? he's a horn guy with some ultra pro looking exponential horns that he designs and CNC's himself in solid hardwoods, v. impressive.
Most people could not build this project based on your rather superficial video, even if they even had the fully equipped pro wood shop as you do. I would like to say that there are pre cut kits available (or plans for simple horns) with full range Fostex and Lowther drivers out there if you are interested in this type of speaker.
Often but not always depends on the speaker and the cabinet the frequency response of a full range speaker is not very flat and you need to tweak it a bit for better sound. In this case the midrange and part of the high frequency was a bit higher then the rest resulting in a brighter sound that can be fatiguing and needed taming down a bit. Every speaker is different you need to measure and listen. Also the goal is to get a frequency response where the speakers sound live and enjoyable and that may not be very flat. Only measuring and ultimately listening will decide. Hope that helps :)
There are actually 2 layers of 1/8 with Acoust-X in between to make more then a 1/4. The main layer is 1/8, then strips of 1/8 with Acoust-x added in between (you can only see some of them as some are a few mm shorter) and a lot of 3/4 inch bracing then dense insulation in between, it is fairly solid. The bracing is the most important part. If you prefer you can add as many layers of 1/8 as you like. Hope that helps.
Question: won’t the bass waves coming out the folded horn be 180 deg out of phase with the sound waves coming out of the front of the driver? Aren’t pressure waves at back of driver 180 deg out of phase with those coming out of the front?
depends on the driver and enclosure the frequency response may have a peak or a dip at certain frequencies and needs to be corrected. but usually not critical
the W8-1772 is suitable mainly for the back-loaded horns, the W8-1808 can be used in open-baffle but if you have the 1808 it is not a big difference use it
@@Gabster1 thank you for the reply I have the 1808 and find it better in 30 litre sealed box than OB but I would like to try your horn build 🙏🏻I am new in diy hobby and learning
So lucky to have a father to show you that stuff - and all those tools on hand. I would have loved to learn some of those things growing up.

Speakerbuilding is a fascinating hobby and here is a high quality good looking build. Liked
I hope I become as cool a Dad as you are! Nice job both of you!

Thanks, these are nice drivers for the size, always nice to build something special vs buying.
I bought speakers similar to these but much smaller (Closer Acoustics OGY). Yep, it’s exactly what you described but I also have bass.
Excellent work from GREAT DAD missing such work in KERALA
Impressive frequency responce
Awesome Project. Love the teamwork!
Thank you
😀😃😄🙂😊😋Wonderfull.Awesom. A Love it. Tang Band forever. Nice Speaker.
Fantastic work you guys!! Some hi-res stereo recordings using good mics would be really welcome.
Subscribed. Thank you for sharing your design. A very tempting project for sure...certainly sold on the drivers .
Thank you, you are correct can not go wrong with the drivers.
Classy workmanship

Шикарный звук, очень достойный! Сразу видно, что сделан опытным человеком, знающим предмет. Очень впечатлён!

2:20 Nice Model X!
Dear sir please share 15 inch woofer old altec big cabinet theatre model thanks

Thank you for the kind words yes the music at the beginning and the end is recorded from the actual speakers.
Wow, amazing sound. Great job.
Wish I grew up with a father like you
Great speaker and nice workshop.
Wonderful Team.
Wonderful
Wow…Thank you so much for this!

Interesting project.
me encanta como abordan el proyecto y tener entretenimiento de ese tipo. me encanto lo detallado que es el video ! y lo preciso de todo.
Gracias

Great job!
What software did you use to calculate the horn?

Excellent job, do you feel still need a sub for that FR driver and box?
Wow...sounds amazind. 👌👌👌

Great video thanks. How low does the bass go from these speakers in Hz? Great job by the way and thanks for sharing this.👍
Great for most music but if you like heavy bass I would add a sub to cover from 20 to 50
Gaby if u need to use this FR spesker for edm techno and pop would u be happy. Maybe a sealed subwoofer what would u say
Awesome video 🤘
I would love to buy 2 of those boxes from you. I wonder what you would charge to make one?
I wish I had the time also shipping would be huge some hardware stores could possibly cut the pieces for you to assemble
Love this video. Can I build a box like that for a 10 inch subwoofer
Look for scoop. Better is 12 or 15" driver System.
You might look for DIY plans for a Kipsch horn.
Nice 👍
The response curve is very doubtful.
As well in the bass with a pavilion, as in the treble with a double cone.
Smoothing is undoubtedly extreme.
If I do this project I will use spray foam as stuffing.
did they have enough bass to use them outdoor?
Why even use a cross over in a coax please help? As im thinking of a diy myself.
Often but not always depends on the speaker and the cabinet the frequency response of a full range speaker is not very flat and you need to tweak it a bit for better sound.

How did you bend the plywood
Use 1/8 plywood it bends easy add 2 layers or more together to create a thicker result
1/4" curved plywood? Looks almost as thin as veneer to my eyes! Could it be 1/8"?
There are actually 2 layers of 1/8 with Acoust-X in between to make more then a 1/4. The main layer is 1/8, then strips of 1/8 with Acoust-x added in between (you can only see some of them as some are a few mm shorter) and a lot of 3/4 inch bracing then dense insulation in between, it is fairly solid. The bracing is the most important part. If you prefer you can add as many layers of 1/8 as you like. Hope that helps.
@@Gabster1 Thanks!
Does anyone have any 3d-files for the build? Would be fun to play around with!
Epic!
Wich cross you used..sir...thank you
Can you play this please with jazz and vocals?🤔
They play jazz and vocals very well
Luz like jbl 4530
Question: won’t the bass waves coming out the folded horn be 180 deg out of phase with the sound waves coming out of the front of the driver? Aren’t pressure waves at back of driver 180 deg out of phase with those coming out of the front?
Why do you need a crossover network when it's a full range...?
depends on the driver and enclosure the frequency response may have a peak or a dip at certain frequencies and needs to be corrected. but usually not critical
Can I use Tang Band 1808 instead of the driver u have used. Also why did you choose this vs the 1808 would be keen to know
the W8-1772 is suitable mainly for the back-loaded horns, the W8-1808 can be used in open-baffle but if you have the 1808 it is not a big difference use it

Isn't this a transmission line?
yes it is
This isn't actually a horn,. It's a rear ported reflex due to the negative expansion.
Negative expansion? Yeah sure buddy.
@@briandeeley1599 Yes, negative expansion
And you know this just by looking at it it? And you know this how?@@anthonymattock4754
...like when you need to fart but burp instead, I reckon...
The length of the horn should be based on speaker size and desired tuning frequency, not just 9 or 10 ft.
yes yo are correct but it ends up being around 9 to 10 ft
Bulb= noise
sounds boxy and muffled.
People don't cut tie wraps like he did on his crossover. Those loose ends will cut you like a turkey at Thanksgiving. Flush cut please.
😅😅sorry,but tue wrong damping Material. Rockwool in a open construction is never a good idea.
Could you talk s little faster?
I have gotten better lately 😀
