Why do idiots keep talking about the cost of the tools to build something? Do you think he bought the tools and materials, built the speakers, then threw the tools in the trash? I have had some of my tools for decades and built hundreds of projects with them. I have also sold a single item for more than one of my large machines costs! Don't be so damn stupid.; I hear this all the time!
A most excellent project! I used to work in a audiophile store many years ago, and this is the type of product that was often sold. If I may make just two suggestions. The first is when preparing the channel for the wire run, to use a flexible plastic tube so that if the wire ever needed to be replaced it could be done easily. Second, before gluing the halves together, oil the acoustic chambers so that the wood is protected on the inside as well as the outside of the cabinet from the effects of humidity. Other than that, it is an excellent project again!

Very well structured video. First show the amazing result then show the way to get there so the watcher is motivated to stay till the end. Other DIYers should take this as an example of how to do it.
The most improvement is separation. You can clearly hear the low frequency sound clearly. This is with cheap $3 speaker. It'd be better with bigger and better speaker assuming the design still allows it to shine.
Try M This was both accurate and non-destructive. Thanks for being different with your criticisms. Everyone here seems like they want to shame the person who built such an abomination.
Nothing is an effort if you enjoy what you do and it's more than obvious that this man enjoys what he is doing and is excited about sharing it... Have you ever heard of a Crepe Hanger, it should have your photo next to it, in the dictionary....
Or you can see it for what it is - a clickbait video with speakers (boxes) that in reality are not cheap. It doesn't sound good at all. Did you not watch the video? The wood is nicely crafted, but the speakers drone out the sound.
This comment is underrated. It honestly knows what the context of this channel is. And unlike 90% of the comments here, is not an arsehole of a question/request. TLDR; This needs more upvotes, people!
Instead of putting the drill in reverse, try keeping it in forward and pulling out several times while spinning throughout the cut. The flutes are meant to act as an auger to pull out wood chips from the hole, so putting it in reverse sort of defeats the purpose. Even though it does feel easier, you're still putting more strain on the drill bit and will cause it to overheat or break sooner. Great project though, and really well executed with simple tools.
Wow, I even heard a difference on my iPad speakers. I like how it amplified and carried the lower frequencies more, that’s missing from a lot of speakers. Nice tone from wood too, makes a difference to bass notes.
Definitely better sounding than before, but many comments mentioned the results do not justify the effort. I think they may have missed a more important point. I admire your woodworking and I have learned something on that front. I used to dabble in electronics and the results really didn't justify the effort and expense, but the reward is in the building process and the satisfaction of creating something. Thanks for sharing.
Chomp , your correct, the journey is the fun part, some people don't understand creative folks! they always seem to equate things in a monetary manner!...
Impressive. Over 1.7 million views in about 30 days. What I learned from this video is that you can make CNC quality work with ordinary shop tools anyone can buy from Loews or Home Depot. The planing of how to make the box and craftsmanship is top notch. About the end result sound quality. It's not "Awesome". The speaker box's tuned path aids the low side of the mid-range. To me,, it's annoying. About 40 years ago I followed an article in an audiophile magazine on transmission line bass cabinets and built one with an 8 inch woofer. I did the math on how long the folded path needed to be to make the low bass better. Let's assume that little speaker had the drive to move the air needed for bass sound. To help "tune" it. You would need to make that box's sound path 6 feet long and that's rounding it off a bit.
definitely not a project for everybody either. You must own the tools, and have A LOT of time in your hands. After that, you end up with sound that could be topped by a different set of plastic speakers that still cost less than the materials for the box. But it is a fun project if you are into wood working.
No one can expect low bass from such miniature driver so 6 feet long path is not applicable. I made in past three my own original big projects working down even to 18 Hz but I appreciate his work - most say it is too much work - I'd say it was piece of cake comparing to big driver. and sound is beautiful enough if one had set his requirements.to this kind. . . . .
@@djbis As I read posts. They focus on the speaker performance. This video is all about the build. Upscale it for a 8" driver and a place to put amid-range plus tweeter drivers would be awesome.
@@Mikexception Wow. 18 HZ. I bet watching earthquake movies really shake your sofa with those speakers. I quote "No one can expect low bass from such miniature driver". I would agree. So how does Bose do it with the little drivers they use? I'm not expecting an answer. Just making a point. To me this video was about the building of the boxes for the lame speakers in hopes they will sound better.
Yes, you're right Halfey. He made it small to demonstrate his idea without the time and expense of scaling up to a more complex, costly and unmanageable size. I thought the build and it's scale was spot on as a demonstrative tool. 5 stars from me. Just imagine if it would scale up to an 8" full spectrum driver and covered with a cherry veneer. My god it's all I can do to control my bowels just imagining the potential. Dohn-cha-think?
It's quite amazing how big of a difference a different cabinet and amp can make to even the cheapest of drivers. Truly marvelous! Beautiful cabinets too :)
This is how Bose makes their waveguide etc. small speakers sound so good. I once built a similar folded horn enclosure in a prison furniture factory, turning a pair of 39$ koss headphones into decent sounding, room filling speakers. These would probably sound incredible with some full range speakers (such as the 5” speakers from Bose 901’s) inserted into them.
That’s a tline enclosure. It will literally make any speaker sound amazing. Even better if you model the tuning of the box using the ts parameters. Notice the size difference in the enclosure with its horn effect on the port.
@@davinderc lol, that block of wood, the Equipment and the time put in makes this whole thing cost way more than 3$.. So the 3$ is just a waste of everything else put in...
@@davinderc nope didn't miss the point. Putting garbage drivers into a good speaker box greatly improves sound quality. Point proved. Now that it's done, put GOOD drivers into that box and use that bax too it's full potential. PS David, you need to relax man.
When I get home after 5 from work, help the kids, drop a deuce and eat and see what needs to be done around the house, I could probably try this build myself once I get all the tools and supplies and space and alloted time from the wife. Looks good buddy
I don't understand why people say its a waste, it clearly shows u still can replace the speakers, so at any time he can get far superior ones to put in. yet still, kinda shows how the $1000+ speakers are made sold in Europe :D
The most valuable thing we have in life is time. He just wasted x number of days doing something that is NOT cost effective. The sound quality is nicer, but really it is a complete waste of time.
Its still more productive than watching ytb videos like this. Plus doing projects like these always educates you further, especially if its a project he does with passion. Its just in the definition of what "a waste of time" actually is. I mean, you could define basicly everything as a waste of lifetime. Its up to everyone themselves what they do with their free time. And as a viewer, its just nice to see his passion to this project, and how much you can actually improve cheap as heck speakers. Ik the effort isnt worth it that much, but Im sure he enjoyed doing this.
People can't speak their mind to even do some constructive criticism rather than sound completely dismissive. Too many politically correct and apologists in commentators. The real jerks won't hit like subscribe or even bother to comment.
Because the box doesn't really make it sound better. There's a noticeable delay in the low ends. The separation makes it so you can hear it a little more clearly but the sound quality is still poor. It doesn't compare at all to 1k+ speakers which normally have very specifically engineered boxes to get the most out of the drivers. It was a pretty cool woodworking project and looks pretty.
Oh dear, is that what they say to make you fork out 1k+ ? Very specifically engineered ? Haha. I'm an engineer and I can tell you 'engineering' doesn't cost anything. Just like women's cosmetics, the cost is all in the presentation and marketing. Got to love 'audiophiles'. LOL
I really enjoyed this video. Waching you work. It made me realise what can be done and how what kind of tools there are and how to use them. The craftsmanshio you display is really beautiful to watch in a world where everything is made cheaply, not to last and people are terminally dependent on large scale and wasteful manufacturing processes and NEVER DEVELOP ANY SUCH SKILLS THEM(OUR)SELVES. Great Job!!!!!
right?! I really really hope he just used these as a gimmick for the video and already had some better speakers with the same measurements which were planned for this
Excellent design. The design is not a "backloaded horn" however, it is a transmission line design. The idea is that the transmission line absorbs rearward sound energy. This has two effects 1) there is no (or little) front-rear cancelation, thus extending the low frequency response. 2) Since the rear energy is absorbed it does not provide excitation for the resonant frequency of the box enclosure, hence no boxy boom, giving a smooth level frequency response. The design is less efficient but gives best results from the limits of the speaker. A horn design is where an expanding flared horn is attached to the front of the speaker. This has the effect of matching the speakers acoustic impedance to the impedance of free air - thus giving maximum power transfer. Hence a horn design is very efficient. The secondary effect is that the path difference from front to rear is extended (if the horn is large), which improves cancellation and extends frequency response.
Definitely better, but a deep warble/resonating sound which isn't good - Maybe you should do your lovely project justice and put $20 speakers in it? - Good work :)
Excellent except for one thing. I am an industrial designer and I would have moved the speakers down so that the distance from the edge of the black speaker ring to the edge of the cabinet was the same on top as it is on the sides. Cleaner look. More centered. You are same as me - all power tools are Bosch or DeWalt. And I love that beautiful little chrome hammer. I want one ! Another great video with your super precise work. Thanks. Cheap speakers can shine if given the right home.
Just when I think I know what's about to go on next (@15:35 - plastic speaker rings) "I made a with MDF". Glad I wasn't drinking anything at the time! Ya' got me bud! Beautiful work, as usual.
The sound is enhanced by the solid cabinet. The speaker needs this. Most speakers lack a solid cabinet for the speaker to "work" with. The sound energy needs this for a more "solid" sound.
Excellent upgrade, although like most here, I would have preferred to see you use bigger & better drivers. The cabinet work is superb even though the work for a pair put me off. I think everyone would have benefited by seeing the theory & calcs behind the enclosure deign, maybe an 02 video?
Hi,do you all know that actually he is making a (not sure if he knew though) "transmission line speaker" enclosure? Click on this topic on youtube. Its all about enhance (not quite enhances, but improves the lower frequency down further) from behind loudspeaker through the back of tunnel as the simulation of a long tube folded. But if he tried to recreate this process, he made mistake by redirecting the flow of the sound. Should have been all the way to the back and down (an L upside down 1st) instead of cut short not even halfway goes down 1st. The quality depends: on the driver, amplifier, music itself. This transmission line speakers really work! It was popular in 1980s. KEF was the best (it still is-England)
A lot of people in the comment section have thick skulls. The goal was to take $3 speakers and upgrade them. How much the cost was, in the end, is slightly irrelevant.
It kinda matters if your homemade costs more than better-sounding ones. If you're going to try to optimize trash, don't use fine components. Use other trash to get the best of the trash.
@@testingbeta7169 Please look up the definition of DIY before you tell anybody what you think DIY is. There's a distinctive difference between DIY and hobbyist. Same reply applies to Bruno Marchesi, what you guys had in mind was hobbyist. The premise of the video is rather misleading and click bait. It sets it up like some kind of cheap hack for layman to turn something cheap into something awesome. But instead, few minutes into the video, you realized that it is not that at all. If this video is about how to spend tons of money and time to hand make a great stereo, I would not be tricked into watching this.
@@testingbeta7169 If I did not make my point clear earlier, consider this: If DIY is not about saving money and not about being practical, then it is not DIY. If I had unlimited resources, I could spend 10 billion dollar and 50 years to make an airplane. But I wouldn't go around show people how to DIY an airplane by spending 10 billion dollars and 50 years. Because under those conditions, it cease to be DIY. The spirit of DIY means that almost anybody can do it themselves. You got my point?
True. I bet he cannot do it with chisels and hacksaw. That is my point he cannot get. Everyone can make the enclosure with router, and or CNC machine. For 3 dollar speaker just to make it sound crispy and clear. He uses material and tools, probably the same amount as buying a relatively good sounding speaker. LOL
Chris Russell On $3 speakers? Don’t think they provided the Thiele-Small parameters. But I get your point and you are absolutely right. The amount of work put into the (beautiful) boxes is totally disproportionate to the cheap speakers.
HangGlideTube If only it was so simple to copy Bose. The speakers enhance the lower mids by quite a lot. Hence the ‘boxy’ sound. The mid-highs and highs are untouched. The better amplifier at the end of the video significantly enhance the base performance of the speakers but they still lack a lot at the lower end. These transmission-line speaker could sound a lot better when equipped with properly matched drivers. Considering the effort put into the project, I think that would be well worth the costs.
Yes an argument between lows and mids, Boxy i would say, Over attention in design towards lows masking mids. However fantastic workmanship and great look. Also like to explain, The speaker cone area has to throw air , The relationship between the front and rear of speaker moving in and out, Just plug your speakers up out of phase and you'll find out
I guess thats because his test method is flawed. The full-range drivers were vertically off-axis on the taller version resulting in less highs. He should have turned the speakers upside down so the drivers were more on-axis.
@@deanedgx watch KEF (England) transmission Line Speakers. They produced very good bass, crispy, clear sound quality by using this method. Agree with you re turn upside down this box. ( I made this system, worked very well even on the el-cheapo, old driver/full range, pushed down lower frequency even further)- on 4" driver-full range 15watt olden day's amplifier with 10% THD..
даааа... звук говнищеее))) правда резонанс есть и звук чуть обьемнее, бас даже чуть появился, но 2+2= 4 и 5 не будет. динамики сперва хорошие надо купить)) а потом колдавать с корпусом.
Cabinet design, construction and labor to build is where speaker costs are centered. The drivers and crossover are just a minor percentage and are extremely hyped for the consumer speaker market. Thus it makes perfect sense his re-engineered speakers sound much better.
Ah the power released from selectively designed acoustic cavity resonance and amplification. The craftsmanship here really is just icing ... any cheap speaker is going to sound way better in a properly designed cavity. Most speakers are designed to generate a broad range to cover human perception but the cavity is where portions of this frequency range can be muted, attenuated significantly even shifted by poorly designed cavities that those speakers are placed into. The uber cheap original plastic box that these were put into werre begging to be one up'd by pretty much any half thought out cavity...in this case the maker chose to focus the highs and redirect the mids and lows in a complex way that just seems arbitrary as opposed to calculated (it can be calculated). That said at the end when the speakers were connected to the amps, the Chinese amplifier delivered a much fuller range of frequencies for the speakers to fan out than the cheap 3 dollar board amp. To me the improvement is quite clear...though one could probably make a similarly priced amp and shift it to accentuate the lows and mids and then merge the channel with the other one for highs and get a similar effect for less than the 30 bucks the Chinese amp costed.
13:06 That's actually called a "roundover" or quarter round. Chamfer would be removing the corner and leaving a flat space, not a round one. I know it doesn't really matter, but it might prevent someone from buying the wrong router bit.
@JSK-koubou: In 3:39 there is this funny little "drilling stand" (or how to call it). It looks like DIY project itself. Am I right? If so - could you show us how to make it? If not - could you give us the link to buy it? Thanks in advance.

Very well structured video. First show the amazing result then show the way to get there so the watcher is motivated to stay till the end. Other DIYers should take this as an example of how to do it.
The most improvement is separation. You can clearly hear the low frequency sound clearly. This is with cheap $3 speaker. It'd be better with bigger and better speaker assuming the design still allows it to shine.
Try M This was both accurate and non-destructive. Thanks for being different with your criticisms. Everyone here seems like they want to shame the person who built such an abomination.
ian sutton nope, authentic praise.
Edit: Even re-reading my comment, I’m not sure how you came to any other conclusion.
Taylor Schultz perhaps because you still refer to the speakers as “an abomination” at the end having initially been positive about their potential.
Nothing is an effort if you enjoy what you do and it's more than obvious that this man enjoys what he is doing and is excited about sharing it... Have you ever heard of a Crepe Hanger, it should have your photo next to it, in the dictionary....
Or you can see it for what it is - a clickbait video with speakers (boxes) that in reality are not cheap. It doesn't sound good at all. Did you not watch the video? The wood is nicely crafted, but the speakers drone out the sound.
More an art/woodworking project than a speaker project. Well worth watching.
Would it be possible to do a video on your drill guide please?
yeah, it would be awesome. never saw one of these

Instead of putting the drill in reverse, try keeping it in forward and pulling out several times while spinning throughout the cut. The flutes are meant to act as an auger to pull out wood chips from the hole, so putting it in reverse sort of defeats the purpose. Even though it does feel easier, you're still putting more strain on the drill bit and will cause it to overheat or break sooner. Great project though, and really well executed with simple tools.

I noticed, in more recent videos, this is what he's doing now. So respect, you taught a master craftsman to be even better.
Wow, I even heard a difference on my iPad speakers. I like how it amplified and carried the lower frequencies more, that’s missing from a lot of speakers. Nice tone from wood too, makes a difference to bass notes.
Definitely better sounding than before, but many comments mentioned the results do not justify the effort. I think they may have missed a more important point. I admire your woodworking and I have learned something on that front. I used to dabble in electronics and the results really didn't justify the effort and expense, but the reward is in the building process and the satisfaction of creating something. Thanks for sharing.
the efforts are totally justified just think how great a quality speaker would sound...
Chomp , your correct, the journey is the fun part, some people don't understand creative folks! they always seem to equate things in a monetary manner!...
Impressive. Over 1.7 million views in about 30 days. What I learned from this video is that you can make CNC quality work with ordinary shop tools anyone can buy from Loews or Home Depot. The planing of how to make the box and craftsmanship is top notch.
About the end result sound quality. It's not "Awesome". The speaker box's tuned path aids the low side of the mid-range. To me,, it's annoying. About 40 years ago I followed an article in an audiophile magazine on transmission line bass cabinets and built one with an 8 inch woofer. I did the math on how long the folded path needed to be to make the low bass better. Let's assume that little speaker had the drive to move the air needed for bass sound. To help "tune" it. You would need to make that box's sound path 6 feet long and that's rounding it off a bit.
definitely not a project for everybody either. You must own the tools, and have A LOT of time in your hands. After that, you end up with sound that could be topped by a different set of plastic speakers that still cost less than the materials for the box. But it is a fun project if you are into wood working.
Thank you for replying to my comment. @@djbis
No one can expect low bass from such miniature driver so 6 feet long path is not applicable. I made in past three my own original big projects working down even to 18 Hz but I appreciate his work - most say it is too much work - I'd say it was piece of cake comparing to big driver. and sound is beautiful enough if one had set his requirements.to this kind. . . . .
@@djbis As I read posts. They focus on the speaker performance. This video is all about the build. Upscale it for a 8" driver and a place to put amid-range plus tweeter drivers would be awesome.
@@Mikexception Wow. 18 HZ. I bet watching earthquake movies really shake your sofa with those speakers. I quote "No one can expect low bass from such miniature driver". I would agree. So how does Bose do it with the little drivers they use? I'm not expecting an answer. Just making a point. To me this video was about the building of the boxes for the lame speakers in hopes they will sound better.
With the amount of effort poured into making this project, the modified speaker probably worth at least 100 times more than its original value.
They still sound like garbage, just garbage with more bass. Edit: Nicely made boxes, though.
Yes, you're right Halfey. He made it small to demonstrate his idea without the time and expense of scaling up to a more complex, costly and unmanageable size. I thought the build and it's scale was spot on as a demonstrative tool. 5 stars from me. Just imagine if it would scale up to an 8" full spectrum driver and covered with a cherry veneer. My god it's all I can do to control my bowels just imagining the potential. Dohn-cha-think?

It's quite amazing how big of a difference a different cabinet and amp can make to even the cheapest of drivers. Truly marvelous! Beautiful cabinets too :)
This is how Bose makes their waveguide etc. small speakers sound so good. I once built a similar folded horn enclosure in a prison furniture factory, turning a pair of 39$ koss headphones into decent sounding, room filling speakers. These would probably sound incredible with some full range speakers (such as the 5” speakers from Bose 901’s) inserted into them.
The work that went into a $3 speaker a man who is dedicated to show cheaper isn't always bad.
I'll give you $5 bucks for it
I think it's cute that he taped off on the table where the speakers would go. Precision.
Amazing work ! Had never thought of this method for building the wooden box. Gives plenty of ideas. Thanks !
yup, the butcher block router stuff was pretty cool
That’s a tline enclosure. It will literally make any speaker sound amazing. Even better if you model the tuning of the box using the ts parameters.
Notice the size difference in the enclosure with its horn effect on the port.

I don't understand why people say its a waste, it clearly shows u still can replace the speakers, so at any time he can get far superior ones to put in. yet still, kinda shows how the $1000+ speakers are made sold in Europe :D
The most valuable thing we have in life is time. He just wasted x number of days doing something that is NOT cost effective. The sound quality is nicer, but really it is a complete waste of time.
Its still more productive than watching ytb videos like this. Plus doing projects like these always educates you further, especially if its a project he does with passion. Its just in the definition of what "a waste of time" actually is. I mean, you could define basicly everything as a waste of lifetime. Its up to everyone themselves what they do with their free time.
And as a viewer, its just nice to see his passion to this project, and how much you can actually improve cheap as heck speakers. Ik the effort isnt worth it that much, but Im sure he enjoyed doing this.
People can't speak their mind to even do some constructive criticism rather than sound completely dismissive. Too many politically correct and apologists in commentators.
The real jerks won't hit like subscribe or even bother to comment.
Because the box doesn't really make it sound better. There's a noticeable delay in the low ends. The separation makes it so you can hear it a little more clearly but the sound quality is still poor. It doesn't compare at all to 1k+ speakers which normally have very specifically engineered boxes to get the most out of the drivers. It was a pretty cool woodworking project and looks pretty.
Oh dear, is that what they say to make you fork out 1k+ ? Very specifically engineered ? Haha. I'm an engineer and I can tell you 'engineering' doesn't cost anything. Just like women's cosmetics, the cost is all in the presentation and marketing. Got to love 'audiophiles'. LOL

The amount of work put into the (beautiful) boxes is totally disproportionate to the cheap speakers.
right?!
I really really hope he just used these as a gimmick for the video and already had some better speakers with the same measurements which were planned for this
DjSunexx Me too.
If you watch another video of him on really beautiful speakers, these come back as a comparison. So I fear the worst;)
Excellent design. The design is not a "backloaded horn" however, it is a transmission line design. The idea is that the transmission line absorbs rearward sound energy. This has two effects 1) there is no (or little) front-rear cancelation, thus extending the low frequency response. 2) Since the rear energy is absorbed it does not provide excitation for the resonant frequency of the box enclosure, hence no boxy boom, giving a smooth level frequency response. The design is less efficient but gives best results from the limits of the speaker.
A horn design is where an expanding flared horn is attached to the front of the speaker. This has the effect of matching the speakers acoustic impedance to the impedance of free air - thus giving maximum power transfer. Hence a horn design is very efficient. The secondary effect is that the path difference from front to rear is extended (if the horn is large), which improves cancellation and extends frequency response.

I would like to have seen the speaker parameters and maths for designing the TL enclosure.
Wood sound. Too big port dimensions.
@@nemesissanity8132 No port here. This is a transmission line.
@@drdimtri Whatever.
i guess its a design found online and rescaled for the project, with a tiny speaker like that it would have to be way bigger to get the fundamentals.
Maxxone thats not a port as its not a woofer design but a transmission line wise guy.
Great music selection during speaker testing. Almost felt like dancing.
@Dagwood Dogwood It's pretty much true. But the jazz ones is the ones that make me move catching the rhythm.
There is really a zen feel in all your videos... every move or action is smooth, slow and calculated. :)
Definitely better, but a deep warble/resonating sound which isn't good - Maybe you should do your lovely project justice and put $20 speakers in it? - Good work :)
No, another 25c worth of foam rubber would probably do as well ... dampening the resonance
Excellent except for one thing. I am an industrial designer and I would have moved the speakers down so that the distance from the edge of the black speaker ring to the edge of the cabinet was the same on top as it is on the sides. Cleaner look. More centered. You are same as me - all power tools are Bosch or DeWalt. And I love that beautiful little chrome hammer. I want one ! Another great video with your super precise work. Thanks. Cheap speakers can shine if given the right home.
Lovely box, deserved a much better driver.
I just was saying this, I AGREE
+Cloud Strife. This is what i'm talking about. Peace. :)
Deserves*. You make it sound impossible with the past-tense.
Taylor Schultz: When did he install the driver?, in the past; therefore my sentence was correct.
Suzy Siviter Oh, I’m glad you clarified. During the recording of the video it should have been replaced, presently it shouldn’t because you said so?
And ladies and gentlemen, this is how your Bose was made.
The cat is out of the bag it seems.
True, but they use cheaper speakers and cheaper cabinet material (not wood).
yep crappy hardware, weird designed cases. your paying for the name and the gimmick they push.

No highs, No lows, must be BOSE.
No. Look up IMF speakers.

The sound is enhanced by the solid cabinet. The speaker needs this. Most speakers lack a solid cabinet for the speaker to "work" with. The sound energy needs this for a more "solid" sound.
Excellent upgrade, although like most here, I would have preferred to see you use bigger & better drivers. The cabinet work is superb even though the work for a pair put me off.
I think everyone would have benefited by seeing the theory & calcs behind the enclosure deign, maybe an 02 video?

Hi,do you all know that actually he is making a (not sure if he knew though) "transmission line speaker" enclosure? Click on this topic on youtube. Its all about enhance (not quite enhances, but improves the lower frequency down further) from behind loudspeaker through the back of tunnel as the simulation of a long tube folded. But if he tried to recreate this process, he made mistake by redirecting the flow of the sound. Should have been all the way to the back and down (an L upside down 1st) instead of cut short not even halfway goes down 1st. The quality depends: on the driver, amplifier, music itself. This transmission line speakers really work! It was popular in 1980s. KEF was the best (it still is-England)
@@massudcnee6649 It's a modified transmission line, not an actual transmission line. Horns are not transmission lines by strict rules.
Молодец, хорошая работа, видно трудолюбие и умелые руки!.

The goal was to take $3 speakers and upgrade them.
How much the cost was, in the end, is slightly irrelevant.
It kinda matters if your homemade costs more than better-sounding ones. If you're going to try to optimize trash, don't use fine components. Use other trash to get the best of the trash.
Bought $3 speaker. Spent 300 man hours, using $100,000 worth of equipment and tool, modified it to sound like $10 speaker.
Agreed. This is all about the pleasure of making them and as a proof of concept.

@@testingbeta7169 Please look up the definition of DIY before you tell anybody what you think DIY is. There's a distinctive difference between DIY and hobbyist. Same reply applies to Bruno Marchesi, what you guys had in mind was hobbyist. The premise of the video is rather misleading and click bait. It sets it up like some kind of cheap hack for layman to turn something cheap into something awesome. But instead, few minutes into the video, you realized that it is not that at all. If this video is about how to spend tons of money and time to hand make a great stereo, I would not be tricked into watching this.

But I wouldn't go around show people how to DIY an airplane by spending 10 billion dollars and 50 years. Because under those conditions, it cease to be DIY.

True. I bet he cannot do it with chisels and hacksaw. That is my point he cannot get. Everyone can make the enclosure with router, and or CNC machine. For 3 dollar speaker just to make it sound crispy and clear. He uses material and tools, probably the same amount as buying a relatively good sounding speaker. LOL
The high frequencies became less, and the low frequencies appeared "like from a barrel". Thank you for the video!
Although a VAST improvement, they have a "stuck in an oil drum" kind of mid bass.

On $3 speakers? Don’t think they provided the Thiele-Small parameters.
But I get your point and you are absolutely right. The amount of work put into the (beautiful) boxes is totally disproportionate to the cheap speakers.
I don't think that the colouration of the sound is an improvement - it just sounds different, not necessarily better.
HangGlideTube
If only it was so simple to copy Bose.
The speakers enhance the lower mids by quite a lot. Hence the ‘boxy’ sound. The mid-highs and highs are untouched. The better amplifier at the end of the video significantly enhance the base performance of the speakers but they still lack a lot at the lower end.
These transmission-line speaker could sound a lot better when equipped with properly matched drivers. Considering the effort put into the project, I think that would be well worth the costs.
Enjoyed watching your skill and creativity. Big difference in sound, but base sound cannot be adjusted. Just the same, thank you for posting.
Before it was tinny then after it was mid-range boomy. ")
Yes an argument between lows and mids, Boxy i would say, Over attention in design towards lows masking mids. However fantastic workmanship and great look. Also like to explain, The speaker cone area has to throw air , The relationship between the front and rear of speaker moving in and out, Just plug your speakers up out of phase and you'll find out
BTW I give this youtuber the thumbs up for what hes done excellent, As I've done this myself, I recommend give it a go, Its fun
I guess thats because his test method is flawed. The full-range drivers were vertically off-axis on the taller version resulting in less highs. He should have turned the speakers upside down so the drivers were more on-axis.

Cabinet design, construction and labor to build is where speaker costs are centered. The drivers and crossover are just a minor percentage and are extremely hyped for the consumer speaker market. Thus it makes perfect sense his re-engineered speakers sound much better.
なんだ､ただのプロやんけ…
Ah the power released from selectively designed acoustic cavity resonance and amplification.
The craftsmanship here really is just icing ... any cheap speaker is going to sound way better in a properly designed cavity. Most speakers are designed to generate a broad range to cover human perception but the cavity is where portions of this frequency range can be muted, attenuated significantly even shifted by poorly designed cavities that those speakers are placed into.
The uber cheap original plastic box that these were put into werre begging to be one up'd by pretty much any half thought out cavity...in this case the maker chose to focus the highs and redirect the mids and lows in a complex way that just seems arbitrary as opposed to calculated (it can be calculated).
That said at the end when the speakers were connected to the amps, the Chinese amplifier delivered a much fuller range of frequencies for the speakers to fan out than the cheap 3 dollar board amp. To me the improvement is quite clear...though one could probably make a similarly priced amp and shift it to accentuate the lows and mids and then merge the channel with the other one for highs and get a similar effect for less than the 30 bucks the Chinese amp costed.
Amazing effort!
You just transformed a 15 bucks speaker into a 40 bucks speaker sound!
