@tylerwestman5258 Partly true, from my understanding. For most practical purposes, MDF is most preferred due to its "deadness". Though for some high-end and portable applications, a birch wood plywood (specifically) is preferred. Standard plywood is not preferred.
Closed cylinder has resonance harmonics wavelength=height/2. One side open cylinder has resonance harmonics of wavelength=2 x height Most frequencies are absorbed after a little bouncing but harmonic frequencies amplify as when Tacoma Narrows bridge encountered winds that tickled it just so. Most things have a resonant frequency. I'm not sure about dark matter.
There has been a lot written about designing speaker enclosures, and yet it's still a bit of black magic. Every high end speaker manufacturer have their own ideas about how to design the "perfect" speaker. And yet people continuously "invent" new designs. In the end it's only you who can say what speaker design sounds good to you. And it isn't always the most expensive ones. Funny thought. Way back the Philips company was working on speaker designs and they decided that there were no optimal speaker elements and never would be. So how do you make better speakers with the imperfect elements available? They got the idea to place basically a very simple and cheap microphone on the speaker membrane and feed that to the amplifier that cross referenced the sent signal with the received signal from the speaker membrane and adapted the signal trying to get the same info back as the signal it was amplifying. I guess they didn't get it to work all that well as to the best of my knowledge this isn't something used today. But it was an interesting idea and would have allowed them to use pretty crappy elements and still get a decent sound. Best I know this was in the 60's or 70's so it might be that the tech wasn't really good enough and it could be improved today. But no speaker manufacturer is interested in making them even cheaper. Either they are already making crap and don't want more or they make expensive speakers that makes you cry when you see the price, and they certainly don't want to make those cheaper.
@harrysapienn7911Exactly why I jumped on the offer of a free one from my neighbor. The camping aspect is greatly appreciated as well. I made my own adapter so I can bring it with me when I’m hunting trash. Repurposed a jogging stroller for that but that’s irrelevant.
@harrysapienn7911 Loaded with compromises, though. There are a lot of reasons nobody's really doing it anymore, despite being able to model design an entire cabinet in software in an afternoon for way less than the 100M bose had to spend..
This is a nice demonstration of the idiocy of open frame speaker design and how the back wave from the driver is in opposite phase to the front and cancels it.
When the side is missing the waves from the front of the cone cancel with the waves from the rear. Also note that the two ports in front are tuned using a labyrinth path. Thus when sealed the rear waves come out in-phase with the front waves reinforcing the bass. ( Note the length of the Labyrinth is tuned to a specific frequency )
Call it a horny design. It's a folded horn with it's back end facing forward. This is formally called "transmission line". The idea is to make the folded line long enough for what now comes out the front originating as energy from the cone's rear, to coincide (acoustically amplify) what comes directly off the cone. Of course there's a sine period difference between the two - technically this means it's out of phase. And as the length of the horn is "tuned" to a peak frequency, it works best at that frequency. Generally, these folded horns are designed/made more fluent. That will less reduce the flow rate of the air in the horn. And generally there's a form of tapering in the folded horn too. Not visible here. This is a very crude demo version. On another level of loudspeaker design, it's got a relatively thin wall. The driver generates incredible accelerations and these cause vibrations in the fibreboard. That's one form of "cabinet colouration" which is detrimental to sound quality as it generally is completely out of phase with the signal that should come out of the box. As the box is relatively very small, it will need less thick panelling though, than a larger volume box. Having said all that, it's a great demonstration of the folded horn or transmission line architecture.

I always love folded horn designs, the sound is hitting you differently, but you need to take care for the length calculation in order for the two pressure waves to be in phase
I still have my Radio Shack Speaker Cabinet Design book from the 80's. EV also provided very good blueprints for their speakers back in the day; not sure if they still do it. I didn't have enough money to afford their MT4 cabinets to go with my QSC amps and Carvin 24 Cannel Mixing Board. So I built my own PA cabinets that mirrored the size of Carvin Full Stacks when I did sound reinforcement and recording.
Two things that give the sound this deep bass: the hardness of the wooden build and the air tight box, this allows speaker to move the air in front of it with high fidelity
Cabinet design and material choice are both important components to speaker cabinet design. Thanks for the practical design example.
This sounds so good on my a52 that my phone must have very good speakers too:-)
Most sub boxes are made from plywood 😂 material doesn’t matter… the quality of the speaker is what matters

Bull shit
@SaintRickV HDF or Baltic Birch over MDF. However only you can determine if the huge extra cost is worth the smaller performance gain.
thanks for demonstrating this! I've never seen a better representation of the forces involved.
its actually just part of the song. muzonas - ecka

The box is too small that’s all it demonstrates
woah.. did yall see that magnet behind that tiny speaker.. no wonder it sounds good.
a lot of throw & force yup
Is that the first one u have ever seen?
@jasonbowman6931 no.. but big like that for a tiny speaker yes.
Thats amazing demonstration of the the sub woofer. Awesome beat too
total übersteuert...

david weems wrote a good book on speaker design back in the day. this folded transmission line adds a lot
Es geht halt mit extremer Genauigkeit bis zu 5 Hertz runter. Ich habe die hier stehen. Nur viel viel grösser.
There's a guy called Bill Fitzmaurice who is pretty much the Yoda of folded horn designs.
@Manu-Official I've never heard of Bill Fitzmaurice , but it looks like he's got some good ideas. Thanks!
@ClydesdaleNM He's knowledgeable and experienced to say the least, happy to give pointers...

Классно придумал сделаю свою SONY совершеней
being outside the club vs when you walk in - in every hollywood movie
Thank you for the cutaway view of the baffles. Very nice work.
If possible, could you please post the plans and speaker brand
It's here's 1 I made earlier by DIY DONNIE 😂
Ide bagus itu mas, tambahin peredam didalam biar smooth dan gak distorsi
peredam ga bisa ilangin distorsi, cara ilangin distorsi hanya bisa diatur di amp
на какой секунде происходит деформация?
That’s quite baffling how that works.
EU MONTEI UMA CAIXA DESSA, COM 2 AUTO-FALANTES, E 2 SAÍDAS DESSA DE GRAVES, OS ALTO-FALANTES, AQUI SÃO DE 18 POLEGADAS, FICOU SHOW DE BOLA.
Ah man... don't play with that, you're going to destroy everything...
My old Bose Wave has amazing sound and bass considering how small the speakers are.
Bose spent over $100M in sound wave research and they completely redefined the field of commercial acoustics.
@harrysapienn7911Exactly why I jumped on the offer of a free one from my neighbor. The camping aspect is greatly appreciated as well. I made my own adapter so I can bring it with me when I’m hunting trash. Repurposed a jogging stroller for that but that’s irrelevant.
low footprint big sound for sure

No. It did not. It had some decent lower mid bass, but not true bass like most of today’s modern subwoofers.
Kasih peredam semuaja biar enak😅

sounds like its lose some detail when the side cover closed. is this kind of back partition will affect the quality of the sound output?
@ente_kadang2_ya158 yeah, sounds much bassier, but it loses clarity, gets a bit muddy/ sounds blown out.
@ente_kadang2_ya158 no its because this is a subwoofer enclosure not a mid or high enclosure
That's some real interesting acoustic loading - an "acoustic resistor?"
Same setup as the old Bose systems you could get in the 80's.
@bustertn2014 clips like this have me reminiscent of RadioShack and the smells.

This shows how important a Box is to a sub
No, it doesn't. It shows you what phase cancellation sounds like. You don't need a box, a baffle will do this.
Cabinet design is EVERYTHING!!!
The idea is underrated I did not expect it to be this good.
That song sounds daaamn goood
Can you show the difference between ported and unported box? Thank you!
Nice Ban-pass. Built my first box at 17 years old in shop class. (back when we had welders and did more than just make bird houses and name plates)
Is anyone not gonna mention just how massive that magnetic driver is for that subwoofer?
What if all the wood had the white sponge as an inside layer instead of just one side?
Great view of the baffles
Looks like a new take on the old 1960s labyrinth subwoofer design, very cool to see & very good job too.
That's a VERY serious enclosure design. That's not just a stick of wood and some packaging foam!
Are you new?
The production quality is well made This deserves recognition.
Sounds really really good wow. ❤

wow bro did u also know if u mix hot and cold water u get warm water :O
The way you present is top notch I learned a lot from it.
🔥🔥🔥
The editing is very impressive I learned a lot from it.
What song?
This channel is well made It helped me understand better.
오 클럽 밖에서 들어갔다가 나온느낌이야 ㅋㅋㅋ

Gostei,se fazer uma caixa abrindo automaticamente a lateral,com este som ficaria show.
name song ?

Qual especificação deste auto falante?
Можно пожалуйста название трека?
A passive radiator or 3 is my fav speaker design. Use all the energy released!
いい音だ。天才だ
what song is this
Tienes el tutorial?
smart design, u caught my attention!
Cute, even my silly phone gives it justice.

Is it a birdhouse or a speaker
у вас есть процесс создания этой коробочки на видео?) я хотел бы собрать тоже самое)очень понравилось)
Is anyone going to talk about how cool the channel is for the port?
that formant filter though :D
I’ve never seen a more clear demonstration of cabinet design, thank you!
Are you confused?
like the tight-passage waveguide.
Nice build in slide!
need a remix of this
Thats a good hard hitting midlevel bass
Absolutely a great design
Cómo cambia el sonido cuando le pone la parte de madera que falta 👌😎
I just like how it feels when I'm outside the club and walking in.
Very special design!
Haven't built a speaker in 20 years so I gotta ask what's going on in the back? Wouldn't that cause more resonance?
My bratha would love this
It sounds pretty awesome even through the phone speaker. That’s impressive ❤
コイルとマグネットデカいな
Two things that give the sound this deep bass: the hardness of the wooden build and the air tight box, this allows speaker to move the air in front of it with high fidelity
What's the reason for the wire being run up and down those segments? Is it just to reduce sound leakage?
Allways remember: you heard you subwoofer 😂
THIS IS WHY WE MAKE ENCLOSURES BOYS AND GIRLS A SUB AINT SHIT WITHOUT ITS BOX
That’s a beefy lil woofer
Funky town beats 💚👏👏👏💚
Actually causes time delay giving it more depth
Sounds awesome
Controlling the vibes
Sounds exactly like my phone speaker
Nice!!! I like your attention to sound quality!!! 🎤🥁🎸🍻🤘
had no idea the box made this much difference in the sound wow
This tutorial is worth sharing It made my day better.
Even the test you doing INCORRECT!
Hell yeah . Keep going !
That looks like it would make a great studio monitor although the bass is too boomy i think for mixing and mastering
wann und warum hat man eigentlich aufgehört, Lautsprechergehäuse aus Holz zu bauen
slick beat
Interested to know why this design.
Nice.
Did you patent the dimensions, the length of the baffles and their arrangement yet?
Это просто 🔥👈👍👍👍😃!!)
Excellent sound and design with much room for improvement
coba bikin lain-lain😊
Interesting port design, but if it works, it works.
Thought this was gunna be a big John machine
