Awesome speaker build! Really love the design.
Thanks man. I've been following your channel, you have some awesome projects and your channel seems to be growing quickly, well done!
Thank you! Yeah, totally nuts and way unexpected. Can't wait to see your next build!
Waiting for new videos from both of you guys ;))
Gabriel Costilla I can agree to your comment.

Great speaker, build plans would be amazing
Build Plans would be great!
Nice project! Isolating speaker cavities from each other like you did, will help preserve its true stereo performance. This is one of the best homemade BT speaker I've seen.
Thanks!
wow! That one looks really cool
Thanks
HI
Awesome. Pragtige werk. Altyd lekker om daai aksent op te tel.
Wow. Fantastic project, Love the practical design. Would love to get some build plans for this and some of your other projects as well
Thanks, keep watching, build plans for some of the projects in the pipeline.
You even manufactured the buttons!!! amazing
Thanks
More speaker building! I'm new to it, and would like to learn the basics.
Keep watching, more to come!
Hey thank you for this video, the speaker looks great, i would love some plans to build one like it
Thank Amir.
Listened to your sound test first. I like your aesthetics , especially your 2.1 cantilever design. Very nice compact build.
Thanks
SUPER GOOD! Больше всего понравилось отношение к работе...скрупулёзность и аккуратность изготовление!!!!
Thanks!
Thanks a ton, very inspiring me and really great idea.
Great, thanks!
You do make things look easy enough so that other people could get there ideas from it, that is just great, thanks for hte ideas, i'll keep an eye out for more stuff you make
Thanks man, its great to learn that my builds inspire others and sparks ideas.
Brilliant video as always! Very clean design. Really clever idea to use the pillar drill like a lathe for finishing the buttons. If you're making another compact speaker and would like some advice for battery packs/high quality compact drivers, feel free to shoot me a message :) Looking forward to the next video!
Thanks Barry! This is my first attempt at a speaker of this type. So its a bit of a learning experience. Living in South Africa, parts takes a long time to arrive from abroad as there is not much available locally, so advice to the right quality parts will be a welcome time saver. I'll drop you a message when I am ready to attempt a MK2 of this build.
Great, talk soon!
Barry Llewellyn YT could maybe just leave the information here for the rest of us to see also :)
Man, your videos are a pleasure to watch. Keep up the great work!
Thanks
from what i see is that you put two 9900mah Li-ion Rechargeable Batteries into that battery pack and the micro-usb built in is the way to charge the speaker. However where did you solder the two wires? it's hard to see but it looks like the connections between the battery and the usb port. also which wire is positive and which wire is negative?
JS-Obsidian He soldered them to the negative and positive terminal of the USB port, supplying 5V. This is where you would normally plug in your USB-cable for i.e charging your device.
Of the 4 contacts on the USB-port, the outer two are positive and negative, depending on the orientation. You could get away with plugging in a regular USB-cable, cutting off whatever connector is on the other side, and connecting positive (red) and negative (black) to the power input of the bluetooth amplifier.
i follow you for something like 5/6 month and i don't understand why you don't have much more subscriber :/ your work is awsome ! hope the best for you ;)
Thanks so much! I'm hoping to grow the channel with more awesome content!
;)
Great design idea. The only thing that bothers me is that once the BT amplifier has a problem you have to wreck the build to be able to repair it. Less glue and a few more screws would have been a better choice imho.
Thanks. True, for now this is just an experiment really and my first build of this kind. Mark 2 will need some improvements made and take those thing into more consideration.
watching your tube on silent whilst listening to motly crew is awesome, any chance of a rear scoop sub design less than 18 inch the only one I have is from an old eminence book.
It would be nice to to see the plans!
Very beautiful and clean design! I love it, you're so creative!
Thanks
Hello, any news regarding building plans for this speaker ? Thanks
Build plans please. Awesome project.
Thanks
build plans please :-) this one is incredibly awsome !!!!
Thanks!
Really love this design 😍
Thanks!
Nice design, how do you get to anything if something fails though(batteries/soldering/pcb)?
Thanks! The battery compartment and charger is serviceable, for the rest I'm hoping for the best :) I'll have to give it better consideration next time for sure.
What a great design.
Thank you
youre getting better and better with these designs
Thanks!
Love your work, always provides inspiration. My only wishes are when ordering from Chinese companies or eBay that it doesn't takes 4-6 weeks to arrive or buying tang ban gear is really expensive as the AUD is garbage against the USD and ends up being a rediculous exercise
Thanks. Yes it takes very long from eBay. I don't order from them that much anymore.
maaan that looks WAAAAY better than i expected, very very well done!!!! i want one of that! XD
Thanks!
Great speaker, very beautiful
Tx
love this build........and yes I would like to see build plans....if you don't mind
i like this build. looks awesome and simple
Thanks
Dude you are a beast. I suck at anything where I have to make it.
Thanks
Hi, how satisfied are you with the amp board? I've been looking around buying all kinds and don't like most of em. does this pam8403 based board have an annoying hiss? And when starting it up a pairing sound (or a chinese woman telling you its on -- sound)?
No Chinese woman on this one, just some beeps. You can only hear hiss when holding it up right to your ear. Other than that it is dead quiet under normal listening. It is a decent board, although it only outputs 3watts x 2, which is rather low.
perfect! thanks for the info. 2x 3W is enough for my purposes.
Great Video. Build plans would be fantastic!!
Thanks.
loved it man! I would really like build it , so build plans please , n it would be amazing if u could improvise it with an aux mode , it would be diamante, great work man , great work.
Thanks
Здравствуйте! Подскажите а регулировка звука каким образом осуществляется?
На плате я так понял play / pause, forward, backward?
Регулировка громкости с источника.
Is this 3w amplifier board drive a 10w speaker?
Man! You are hyper Fast!!
Great build and design
Thanks
looooooks gr8 man !!!
Tudo bem amigo, poderia informar qual placa de áudio você está usando nesse projeto? E se consigo comprar na internet.
There is a link to it in the description of the video.
Let me know in the comments below if you would like me to make build plans for this project available.
yes please
yes!
Yes please
Yes. Would really like to build it!
yes please
Love can have one Greetings from the Gambia
Great design! Looks really good except the way you solved it with the on-off-switch and the usb-port. You could have 'integrated' it more into that outer piece of wood without drilling a huge hole into it :)
Thanks! Yes, I agree. A more elegant solution would've been more pleasing. This is my first build of this kind, and I suppose a bit experimental and the overall design can do with some improvements.
Hi, the amplifier is 3w per channel, why do you use 10w loudspeaker per channel? Really filled the 100 speaker? excellent design. Thank you for share us.
The 10w drivers are much better quality than the lower wattage and it avoids any potential distortion at higher volumes.
Material of a Way!
It is now only waiting for 30 to 40 days and begin the gift for girlfriend.
Thanks for sharing!
Great job!
Awesome, go for it!
yes please build plans would be awsome
Love it! Very well done. :-)
Thanks
Great job, cool project :)
Thanks
how long does the battery last and is it loud ?
Not 100% certain, but I can listen to this on and off during the day without charging. It's definitely long enough for a day of normal use. It is only 6watts in total, enough to fill a small room or for personal listening on a desk.
Really great project. I'm going to make something like that too, but with a 3w-3w Bluetooth board. And the power bank is going to be internal and made by me too. :)
Thanks. Good luck with your build :)
SoundBlab Thanks! :) And, well, I have to start somewhere, right? :)
This was my first small bluetooth speaker build and very experimental, but it came out better than expected and I still use this everyday. That's the fun part of it. Definitely going to make a MK2 with improvements, but with a more powerful amp board and also a self made battery pack.
SoundBlab Great, man! A tip: use TP4056 for recharge the pack (since all cells are in parallel) and two step ups, one for the board (12v, right?) and one with USB female port. With independent switches, of course. How much time it will take to recharge be needed depends only from the number of batteries (and it's capacities (2200 mAh +/- for 18650 cells) and the power consumption. ;)
Yes, thats definitely an option. Have not quite decided on the exact setup I'm gonna use though.
Great project. How long do the batteries last ? Can you leve a link for amp that you're using in this project?
Thanks. The batteries last a day with on and off listening. Link in the video description.
this is so fkin satisfying to watch. Great job
Thanks
Wow!!! Nice I Realy Love Your Design
Thanks
great job bro
Thanks
Very nicely done.
Thanks.
SoundBlab cheers
it looks really nice
Thanks
I enjoyed watching it
Thanks
i love seeing designers who didnt suffer for struggles in making speaker boxes. me i really have to use cutter blades to form a circle and uses metal saw for clean cutting of wood . 😂😌
do you have connected two speakers parallel to one audio channel?
2 are speakers and 2 are passive radiators.
Отлично👍
Tx
Very nice
Tx
Awesome. Build plans to me please. Thanks!!!
Really nice and cute!
+Kuman Technology Thanks!
Sir,
Can you make a video on how to add SD card module to the speaker in this video plz
Nice work, but why didn't you put in a passive radiator for extra bass?
Thanks. There are two small passives in the back of the unit.
Cool !
How loud is it compared to jbl pulse or bose soundlink mini.
Its only 3+3watts running through 10watt speakers. It goes loud enough for personal listening and will fill a small room, but I think the jbl and bose has more power.
Alright. Great build. Thanks.
I like all of your speaker builds. I have a query, can I use 2 * 10w 4 ohms speaker with pam8403 amp
Yes, the PAM8403 can only push out 3Watt of stereo power. 10Watt speaker on each channel will be more than able to handle it.
Thanks a lot.
Also what are the dimensions for that battery pack? I can't find it anywhere
JS-Obsidian Given these are 18650 lithium-ion cells, they are 18mm in diameter and 65mm in height, so the battery pack would be about 4cm wide and 7,5cm tall.
Also, the used cells are probably some cheap chinese ones claiming to be such high capacity. Generally speaking, i would be very suspicious of 18650 cells claiming to have any capacity over 3000mAh.
You can look up some videos on youtube of people testing the real capacities of the chinese cells. You can find yourself lucky if they reach just 900mAh of the claimed 9000.
are you gonna incorporate rgb led to your speaker designs in the future? Lg and sony have the best store build designs. nice job. looks like it was factory made
Thanks. I could certainly try that in a future build.
sir I have two 10w Sony company speakers which module should I use
You can use the module in this build or use the one in the new build that I have done here: th-cam.com/video/b8xwcJfwUmM/w-d-xo.html
Links to all the parts are in the descriptions of the videos.
MUY BUEN SONIDO TIENE INTERESANTE ...
Gracias
Hay +SoundBlab I would also like to have the Build plans for this Build because it looks awesome 🙆.Nice to watch your Videos and Builds.
Thanks
I know a South African accent when I hear one and you sir must be from South Africa
yes
Love your build videos, please keep them up, one question though, how do you plan / are so successful using passive radiators with your designs?
This was my first try at passives. These units had no specs so it took a bit of trial and error. But you can usually work within the specs of the driver and design for a ported enclosure and then use passives that are similar in size in area to the opening of the port. General rule of thumb is that the passives should be slightly larger than the drivers you pair them with.
SoundBlab appreciate the info! I've toyed with winisd, still learning more into the fine details though, didn't know about the port size to passive correlation though, good info thank you.
sweet!
Thanks
Very cool bluetooth speaker i would like build plbs for this 👍👍👍👍
Thanks. Lets see how many people respond to the build plans, then I will consider it :)
So did you consider it? :-)
Build Plans Please!!!
build plans please. great video
Thanks. This build was very much experimental with parts that I had no idea how they will perform. I will most likely produce build plans of a similar and improved build soon.
Plans would be awesome
very nice project. I would also like to have the build plans. would be great.
Thanks
Good job bro. Any link for 4"small bluetooth speaker you did.
Thanks. None right now that uses 4inch drivers.
in your feeling does it sound like cheap ass speaker or something more? Would u compare to other bt speakers on the market?
Right now I don't have anything similar in my possession to compare it to, but to my ears they sound decent with the obvious limitations of bass response for a speaker this size. I will have to get something to compare them to though to give you a better answer.
Why not the speaker are separate? Now there is one volume for both speaker, is this a good idea? Sorry for my english hope you understand what i mean.
Just a matter of preference, some people make a separation and individual chambers for each speaker some don't
Yeah it really doesn't matter acoustically as long as the speakers are the same all you are doing is reducing internal volume by putting a wall in between.
very cool
Thanks
maybe you can post your build plans on instructables ;) and amazing bluetooth speaker, I think I am going to make this soon, and pls create more speakers ;)
Thanks. Keep watching, more projects are on the way!
how much did this project cost you?
what are you use for cover speackers?
It is speaker grill foam (6mm thick). There should be a link to the product in the video description.
Hello, I love this project. Could you please drop the plans?
Thanks. You can purchase the plans here. It really helps me to keep the channel going: soundblab.net/product/portable-bluetooth-speaker-v1-0-build-plan/
You are the best
Thanks
the best that i ever seen before! all that i want to know is... what kind of battery u r using and the connector!
Thanks. The batteries are 18360 lithium ion types. The batteries are in a power pack that handles the charging. I take the power from the USB port. Links to all the parts are in the description.
SoundBlab you think that i be able to use lipo batteries 7.4v?
The amp I used in this build requires 5Volts. You will have to step down the voltage with a buck converter.
SoundBlab thank you verry much
How does theese speakers compare to like a JBL charge?
I dont know. I have not heard a JBL Charge before.
thank u
Pleasure!
Nice video, what did you use for buttons? Thanks
Thanks. 6mm Aluminium rod.
hey nice one....would I can get one speaker
please make the plans
Awesome speaker! Buildplans pls :) onlie thing i have to say, those cells/batteries you are using are 100% fake and cheap china product. There is no way they can put 9900mah into a 18650 sized batterie.
id like to see something similar in maybe 4 times the size, still compact but with amazing sound for maybe a small party.
My Creative soundblaster roar can go veeery loud and is able to fill a whole room with like 20 people in there with music, so you can do that to ^^
Maybe the next bulild you do with 2.1 so you have L R and a Subwoofer in a compact build? There is a BT controller that runs with 12v (so you need to put 4 of those 18650 batteries in series) and can handle over 100watt, if you want i can send you some links if you are intrested :D
Yes, the batteries are cheap China versions. I'm sure the claim of 9900mah is false, but so far they have been holding up well on a charge.
I am planning a 2.1 portable bluetooth build for the future. What controller do you have in mind?
+SoundBlab As a Bluetooth amp i guess the Best are the tpa 3116. there are some with a 2.1 crossfader to Controller which freq goes to the subwoofer and which to the high-mid-speakers. www.amazon.com/gp/aw/d/B01IH5THTY/ref=mp_s_a_1_1?ie=UTF8&qid=1476634023&sr=8-1&pi=AC_SX236_SY340_FMwebp_QL65&keywords=tpa+3116+bluetooth
Yes, the sound quality of these are not bad at all for the intended use. However, the one you mention has a rated working voltage of 18-24V DC. We need 12V to run off a battery without complicating things. This one does, but I have tested it and don't like the controls, they make no sense when trying to control the crossover FQ: www.amazon.com/dp/B016ZQ0HK0/ref=psdc_537344_t3_B01IH5THTY, and I have noticed a hiss at lower volumes. I have sourced a small TPA3123 20Wx2 + 50Wx1 amp without bluetooth on-board, but can pair it with a bluetooth board to make up the complete bluetooth amp. Have not tested it, but intend to use it in a build soon. Lets hope for the best!
SoundBlab jeah, there are many of those tpa3116 controllers out there.... i just searched for one and sent it here. I guess there are many other with better quality and and better controlls. im looking to get something that can controll even a 40mm subwoofer so i can use it at home with my 5.1 speakers ( with passive subwoofer which does not need external power ) and then i dont need to plug in that huge AV-Reciever and all that stuff....
since you two have alot more knowledge about these products, can any of you advise me on a small amp board with bluetooth, preferably 2.1, but also has a 3.5mm audio in jack?
