As a professional electronics and audio tech with some 44 years experience, may I make two suggestions? One, never use tape as insulation. Always use heat shrink tubing instead. Safer, more permanent, more professional, and better looking. Two, bring line level inputs to the outside of the cabinet, so you can connect audio directly to the amp. Bluetooth is wholly incapable of true high-fidelity audio, so if you want to hear what your speakers really sound like (and those Tang-Band drivers are REALLY good), you need line inputs. Otherwise, nice job!

[@StevenRyan54]

Unless maybe using Bluetooth module that Support LDAC codec

[@dimdimdu54]

He should have use passive radiators instead of this conception to increase the bass, i have the feeling that the bass is totally absent

[@MatthewLong8]

Dope! Great job. I like the aesthetic of the curvy chamber behind the driver for breaking up the rear wave reflection. Also I like how you moved the speaker around to actually demonstrate that the frequency response isn't faked. And I got to say, pretty impressive frequency response.

[@NBC_NCO]

I really like your battery holder. The box reminds me of something classic but yet modern. Very cool looking.

[@dlloyd6300]

That would look beautiful in a Baltic birch plywood!

[@shanebethune9032]

True but I think it’s the density of the MDF that gives it the resonance kind of like the type of wood used in a strata verious which is why they make cheap speakers out of partical board

[@dlloyd6300]

@@shanebethune9032 While I understand what you are getting at, that is the exact opposite of what you want when engineering a quality speaker. In an acoustic instrument like a violin or a guitar, The resonance is an integral part of the design. It reinforces and amplifies the sound of the strings while giving it character. A perfectly designed speaker would be completely inert. You do not want a speakers cabinet to color the sound at all, which is why high quality speakers are extremely dense, heavy, internally braced, and filled with fiberfill to dampen any internal standing waves. The purpose of any speaker is to perfectly replicate the RECORDED audio, and inducing resonant sound from a speakers enclosure is antithetical to that design goal. MDF is actually a very good material for those design goals as it is both dense and inert, however with how small that speaker is compared to with how thick the wood is, switching to a Baltic birch would have near zero impact to the speaker acoustically, but have a dramatic improvement on aesthetics. Cheers.

[@T313COmun1s7]

Rather than sanding the outside, which with MDF is an exercise in futility, try coating the outside with body filler such as Bondo and then sanding that. This way you can get it as smooth as you want and it is prepped for paint.

[@rayzupmuzik8611]

Bondo mixed with fiberglass resin works really well for this.

[@ScottGrammer]

That's an excellent idea. An even better idea would be to make it out of wood. 😃

[@JJ_ExMachina]

@@ScottGrammer ... MDF really does well with preventing unwanted resonance, and it's extremely inexpensive vs solid or plywood.

[@ScottGrammer]

@@JJ_ExMachina Yes, that's true. But MDF doesn't finish well, it's hard to keep precise tolerances with it because it flakes at every cut edge, and if it ever gets damp, it's all over but the crying. It's just a matter of what you want.

[@JJ_ExMachina]

@@ScottGrammer ... Very true, but if treated properly (aka sealed under varnish, veneer, or other water resistant coatings, it will withstand a fair amount of moisture. Majority of subwoofer enclosures used in vehicle applications utilize MDF as their main structure, and those hold up to some serious abuse. BUT you are absolutely correct, and everyone is free to make their own choices. That's the most wonderful part about these kinds of things... there really isn't just one correct answer to this sort of thing.

[@ЯрославКлименков-з3т]

Sounds really good. Reach 70-75herts hundred percent. Really cool !

DIY Speaker: Step 1: Have a CNC workbench...

[@eslemanht7090]

hahaa

[@joseislanio8910]

Lol I hate how almost everything today labelled as "DIY" involves either a CNC or a 3d printer. Kinda pointless.

[@Vothtrucks]

and being a deaf-mute or unable to speak English.

[@Eversor86]

I hate most of these DIY speakers videos. Made in a way that looks like there were only 2 rules - be as fast to build as possible and make noise at the end. Some at least "look" like there were some "sound mathematics" used but then without any info in the video which/why - aka looks like someone just found instructions on the net and decided to make video about it. Half of them made of scrap, half of them not sealed in any way, nearly all powered by "chinisium-grade" electronics - crapiests dc-dc converters, bt modules, amps. No proper tests really made at the end. Some include "rainbow-puke" RGB disco-lights. Wouldn't be surprised if most of those speakers are disassembled for parts for next videos. And worst in all of that is that when I thumb-down and mark as "not interested" in recommended part of the site these videos, it sometimes makes youtube reduce the number of "good" videos too.

[@Кранц-т9б]

МАСТЕР!!!Руки золотые!

[@djstephanpanches]

Magnifique, bravo.

[@DracolegacyOfficial]

your next project should be for the new Dayton Audio Epique E150HE-44, bet you could make one hell of a box for that little monster.

[@MikeMcChiken]

I'm planning on making one with the new epique 5.25 . Need a bigger amp than this though

[@DracolegacyOfficial]

@@MikeMcChiken yeah, i would imagine this battery powered speaker isnt meant for 200 watts

[@nikolastojsavljevic5469]

Beautiful box and so much effort, nice full range drivers but battery assembly and amplifier looks ugly.... You need at least 4 battery in serial and 2 in parallel for that amplifier. Also some paint on MDF would be great... Anyway nice diy project

[@PhiMobileSounds]

I did not even watch the video yet .. Subscribed!!!! Holy stacked fab!!!

[@АлександрКочнев-ж8ъ]

Лайк за труды!!!👍👍👍

[@ItsDextrin]

To get a better solder joint onto the nickel strips, you can roughen the nickel strip's surface with sandpaper before pre tinning with solder.

[@kiwiskiz]

I would add to that, not to solder where heat can transfer to the cells as this can easily damage them, spot weld on a longer tab, and solder to this.

[@va5715]

@@kiwiskiz Exactly, for this reason it would be much easier and better to solder the wire to nickel strips first and then weld them on to the cells.

[@XeonProductions]

Very satisfying watching it being made, and really clean design.

[@MeatPopsycle]

This channel and your work are both dope.

[@kingmakespeaker1402]

Thank you

[@とりけら-z9q]

透明アクリルで蓋をするのは斬新！

[@73kokitch]

Looks awesome mate, good job! But could you show some measurements on the driver.

[@РоманЧернышев-э9у]

I like the fasteners for the batteries, very unusual and lamp-like, but actually impractical, because batteries are for portable equipment and you are unlikely to carry such heavy acoustics with you. But overall, not bad, for the sake of wow effect, well done.👍

[@piotrpawelec2008]

Piękne, po prostu arcydzieło- serdeczności Piotrek z Polski 🙂😘

[@СергейГаденко-х7я]

Обычный фазик сделать и не мучатся ) а так респект за работу

[@denisarzamaszew4395]

Подозреваю что это чв , а не фазик

[@tee-jaythestereo-bargainph2120]

Thats awesome ! One of my bestfriends has a cnc like you love to get the download

[@ksb916]

Great build! I’m surprised you didn’t place the volume control of the amplifier to the outside.

[@CPTFiXtion]

Probably just have it set to max volume and use the phone to control the volume

[@BubbaTech]

I would unsolder the pot and mount it in the plexi...

[@zaquex]

Sensacional amigo parabéns pela criatividade 🇧🇷

[@kingmakespeaker1402]

Thank . I love you

[@EarthPoweredHippie]

Super dope build, I need a custom jobsite Bluetooth boombox

[@Blackbeardyo]

Very nice project would it have been possible to adjust your c&c machine to allow you to put some sort of veneer finish on the bare mdf

[@HDFactory-HD]

На этот раз человек хоть нормальные динамики взял и сделал интересное оформление! Хорошая работа. Думаю на самом деле звучит интересно.

[@йцуке2345]

Двух недостаточно-это динамики Bluetooth: 1) Корпус нужно было за грунтовать и покрасить в чёрный или белый цвет; 2) Аккумулятор можно было бы сделать в 3 раза больше по емкости, тогда его хватило бы на долгое время.

[@RostovDad2]

Корпус не просто можно обработать, а нужно

[@john_jcm_9671]

Esta bien hecho el trabajo,,, la estetica es hermosa,,, la pregunta es si así el sonido es profundo, claro, si los bajos son buenos y las medias frecuencias son buenas y armoniosas....buen video...

[@thuybong2848]

Có máy CNC thích thật.Thỏa sức đam mê.

[@waynepiper6183]

Stunning workmanship

[@drifter905]

well made, great design

[@ΔιονυσηςΓιακουμελος-ξ3ι]

Συγχαρητήρια πολύ ωραίο,με καλή ακουστική. Μπράβο.

[@akashsahoovlogs2385]

Love from odisha

[@iacon6945]

Thích cái loa này quá 😍😍😍

[@TheManeliss]

Sorry but too big for the result... You must put an active filter or a DSP to maximise bass and for lower mids! Do the same with bigger full range... 5" is the minimal. My first 2.1 is from 1995 (3 liters total). With linear amplifiers. Hot in temperatures for a little speaker!!! Welcome class D! But never for high frequences... I build now hybrid 3 way amplifiers. I've found filter module cards to eliminate probs from little enclosures. I appreciate your work!! My job is renew old (from 18th century to now) furnitures in France.

[@venerandarain3]

lol..many layers ,😁👍🏻

[@Чел-е1и]

Очень круто выглядит, жаль что звук не такой который хотелось бы что бы был. За старания респект и однозначно лайк.

[@RW_CreativeMedia]

Nicely done

[@dvjturngwongputhon3964]

สวยมากครับชอบครับ👍👍👍❤️

[@kailumgg6720]

Love it but the thing is it must be tuned very low because how long the port it

[@ienmattroigee1037]

good video

[@trisnawongcilik5777]

nice amazing prototif music

[@yongyuthmeemuang]

I like very good ❤️

[@danluther9078]

Subtitle: "I spent all my money on this CNC router setup and can't afford a palm sander"

[@გაგრიამროველი]

უმაგადესია 👍

[@PopeyitoRD]

Excellent video, but how can I get the plans or the file for the cnc?

[@gajendraprasadsahu703]

Super quality

[@joshrg22]

Also, Drok makes some great 3-4" drivers

[@feronous8207]

All lows no highs, must be King make Speaker lol...very cool tho

[@Noah-or5gr]

its a awsome little setup only thing i would change about it is just some high quailty drivers from some older polks or some from parts express

[@maskedviperus]

Needs better wiring job

[@girijaggu7721]

Super bro

[@ประสิทธิ์ศรีบัวสวน-บ4ฐ]

you are very clever

[@heilnergarcia4346]

Nice! but... where are the Stls, gcodes or something???

[@Diegonanett]

Gostaria muito de ouvir o resultado. Que diferença proporciona o labirinto comparado a uma Bass Reflex comum, etc...

[@luidgifernandez1207]

Ja montei essa TL, bass reflex e a Close. A TL com fs baixo e incomparável. O sub grave com pouca potência e muito forte.

[@Elmuzaki]

Amazing this is very nice

[@BargainSavage]

What a cool build.

[@thanhdinhhd2366]

Mình cũng đã nghiên cứu hơn mười năm rồi ,mới thành công và đưa vào ứng dung .đóng thùng loa kiểu (ma trận) này tiếng bass không sâu ,và chậm tiếng bass đánh không đúng nhịp .với nghiên cứu của mình muốn có tiếng bass hay vẫn đóng thùng theo nối truyền thống .sự kết hợp giữa củ loa bass và thể tích mét khối của thùng loa ,cách bố trí chiều cao ,rộng và sâu của thùng loa kết hợp với vật liệu tiêu âm ,chất gỗ đóng thùng ,và chất lượng củ loa vv mới cho ra chất âm bass hay .mong bạn vô tư đón nhận ý kiến đóng góp của mình .chúc thành công

[@davitherkildsen]

Maybe some clear silicone between the wood and plexiglass?

[@kenhchetao94]

Quá uy lực và mạnh mẽ

[@kylefelipe]

Loved the song.... Remembers me sonic

[@VHung113]

Vỏ loa dày vậy làm như bt nó cũng đã rất trầm rồi, t ko hiểu về loa lắm, ko biết kiểu này b làm theo công thức, nguyên lý nào hay là tự chế, vì t nghĩ đường đi cộng hưởng xa vậy liệu âm trầm có bị delay ko, với lại nên sơn lại phần trong chứ đừng để nguyên bề mặt gỗ thô vậy, bề mặt ko nhẵn âm thanh di chuyển va đập bề mặt thô cũng làm âm bị rè đi

[@paul1349]

Beautiful work can I suggest one thing try to brush the glue that way you don’t have all that work Cleaning up Get yourself a flatBrush they come like six in a pack at dollar store Besides that beautiful work

[@kingmakespeaker1402]

Thank you

[@chigoki-nghethuatgo3634]

Loa có 15W, bạn dùng mạch amply 100W/ch để ghép thì mạnh tay quá!

[@dirf554]

Do you make and sell these? I’d buy one nice work.

[@trongnhanluu7174]

Loa đẹp lắm bạn

[@gopescabang7624]

Mantap bosqu

[@Ted_Kayfer]

A very good project! I create portable speakers myself.

[@theanhkc07]

hay nhưng chưa hoàn thiện lắm. mình góp ý thôi nhé. mica để âm xuống mặt mdf, mdf nên sơn, mica nên dùng loại đen bóng nhìn sẽ sang hơn loại trong. chỗ mica và gỗ phải có lót cao su non. thêm chút đèn nữa là đẹp rồi, sp như trên video chỉ để chơi thì hay thôi chứ chưa thực sự đẹp, thêm 1 chút công nữa là ngon rồi

Hóng admin làm loa trầm cho oto

[@NTT.07]

Xịn sò ah ơi

good 👍 exact replica of bose wave system

[@taiphamduy7763]

Làm ít led zo 2 khe kia nữa thì tuyệt vời luôn

Súper 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

[@UpinkProduction]

I love it good Keep uploading videos like this 👍

[@LeeSangLVS]

Đẹp lắm bạn

[@3dbatman126]

What kind of speakers do you use? They look like 2-way speakers.

[@GabrielJoJo2024]

Wow, This is Amazing 😳

[@JaviersDIY]

This is impressive

[@quinguyen1408]

Wa hay ,cảm ơn bạn

[@TheStonedSpidR]

thought this was somebody actually making something. instead its a machine doing all the work. Its only DIY if you have the machine do all the DIY for you lol

[@kingmakespeaker1402]

Thank you

[@Andykool1810]

Mica cho chìm xuống mặt gỗ để gắn thêm led rgb vòng quanh mica đi bác ơi.

[@chrismooneyham5279]

It sounds EXACTLY like my home stereo system!!! CRAZY!!!

[@alec-s]

Because you're hearing through it... It sound exactly like my cellphone speaker

[@ThanhLong84]

Sao k sơn thành màu đen hoặc màu xanh rêu nhìn cho nó ngầu hơn. Đã làm nắp mica nếu độ thêm led bao đẹp luôn.

[@ademiltoncordeiro1867]

Top demais 👏👏👏👏

Có máy CNC khỏe thiệt

[@youtubetv7000]

Super

[@spitfire155k2]

If you use a downcut bit instead of the uncut in this video you’ll get much cleaner cuts.

[@funtohave5604]

It's so amazing

[@kingmakespeaker1402]

Thank you

[@drazkjourney-jpr]

Superb👍👍

[@JJ_ExMachina]

Very nice... this is more or less how Bose home speakers produce such full sound out of small speakers... They do use a bit of EQ trickery to get a good balance out of their speakers.

[@kingmakespeaker1402]

Thank you

[@dedesulaeman7156]

mantap ey

[@hoangnguyentien5000]

Đánh bóng lên màu đem trưng anh ơi .làm thêm 1 sub điện nữa là hoàn hảo

[@silviuzaporojanu7530]

It looks really good. What you welded the metal with to the batteries

[@kjohns68]

Soldered

[@kartavyasingh9669]

Nickel bro

[@picklerix6162]

Bass is non-directional so you’re better off using a dual voice coil with single woofer in one enclosure.

[@PhuongMienTay1992z]

Nếu có máy CNC thì mọi thứ sẽ đơn giản hóa rất nhiều Sao anh không dùng mic cnc nhỉ.. Làm 1 bộ trong suốt sẽ ra sao nhỉ

[@KhanhNguyen-nm8wx]

Nhu thê nge ko hay

[@michaeljo13]

You should probably do 3- way speaker enclosure video need time.

[@kingmakespeaker1402]

Thank you
