This is by far the most in depth but easy to follow tutorial on this project
But I don't have thermal paste how to apply heatsink without thermal paste
Really nice build. You did a lot of things *right* to get the most out of this. Separate ported chambers with opposing ports was genius.
When that bass dropped, I got back the bass my headphones lacked! Thanks Sorin.
Excellent build! Thanks for sharing.
I love the design and the simplicity, good job!
You are awesome.not only this video help to build my diy speaker but also i got answers to many of my problems.thanks dude👍👍👍
I did learn a lot here, it's good stuff!
Excellent project my friend. Thank you for sharing.
Love your videos man👍. The sound is very good unbelievable bass
Awesome video keep going like this!! Greetings from Greece!
This is perfect for my project I watched it twice
Same for me, so much info great info shared in this video, even if you dont plan to do exactly the same speaker, a lot of idea and mistakes to avoid when working with Audio and Power!!
After some inspiration from this guy, i finnaly made my own bt speaker with tpa3110 amplifier.
You know a lot about electronic stuff, as I've seen in your other videos already. Excellent to mention the correct phase alignment of the speakers. It's something other builders of speakers don't bother to mention. Nevertheless, it's important.
I also like your way of thinking regarding the cooling of the amplifier. Even if it is a box...you showed some "out of the box" thinking in this project.
This has got to be the cheapest, yet good portable speaker build I've seen in here.
Very nice video, And explaination is also too good. Its very easy to understand. Thank you.
Easy, cheap and portable while maintaining the quality 👌. Nice project!.
Sounds pretty good!
Thanks...
it's project is awesome:)))) i'm from poland and watching you videos:)
just found your channel.. great content man, and your spoken English sounds pretty much like mine.. subscribed!
Sound quality is amazing 👍
Ótimo trabalho.
This's so good bro
Brother I really like your way of build and even the talk
THANK YOU My best wishes with you Go ahead
Love what you do
Great project as always! Full of info and mistakes to avoid when building homemade Speaker!! I liked the Audio knowledge shared and also about the battery/ 18650 pack. By far the best Audio Build around on CZcams, everything is not about the esthetic, but more about the knowledge shared through the whole video!! Keep the great your work!!
PS: I would have spray painted the case in black, but it seems that you are fine with the laminate wood color :P
thanks for existing!
Great job
Well done! Thanks :)
Aveam eu impresia ca esti roman imi place ce faci continua=)
Hi Sorin. The line of pam amps are pretty impressive, I've built a few projects with the different chipsets, and all have worked out well. I've been watching a bunch of home made Bluetooth speaker builds lately, and I must say, the few speaker builds I've seen of yours have been the better ones. You have a good understanding, of how best to utilize speaker drivers that other people wouldn't care to use. You also seem to understand, that no every portable speaker has to fit in your pocket, having to use tiny drivers, but crammed to capacity with batteries and other components. I like the way you keep these home builds simple, and effective. (Not to mention) using salvaged parts to repurpose them. Thanks for making interesting informative videos.
Oh yeah,,, rules of cats,,,,, they MUST investigate speaker boxes.
What about the background noise and hiss sound of this chip. Specially in the low input volume.
Very nicely done..thanks alot
Wow. Amazing!!!!
NICE!I build similar portable speaker using same amplifier!
Wow amazing
Really nice one.
That awesome project bro thanks
nice and easy!!! especially good for those who lack experiance or budget to build something serious.
a good carbon fiber wrap and better battary holder and let it rock!
Nice Projects 👍✨💯💡
I would say this is best explained build in detail
Awesome 👍
Nice job bud, Cheers :-)
Very good
Very simple
I like it
Thank you I'm from India but your products link were in Romania luckily I could change the region and it was successful
Nice...! I like it..!👍👍👍
i am impressed with bass. I liked it very much.
Very very impressive Project .
Well done!!! brother...

thank you sir for the verry Detailed tutorial. make more video.
You are a genius
Perfect
Excellent congratulations, I build one for my house.
salut Sorin nu pot sa cred ai un canal perfect
I like this project.
Foarte fain proiect și explicat bine. Succes mai departe!
Amazing :)
Imi place ca abia mi-am dat seama ca ai vorbit romana la inceput :)) fain (de acum, o sa comentez in engleza aproape tot timpul sa inteleaga si cei care nu sunt din Romania)
Frumos video, eu am folosit aceleas difuzoare la boxa mea portabila, sunt best buy
:D
Awsm bro
Bravo!!!
Good one
i like your videos . very interesting videos..
Awsome
nice video
Crazy bass
GG man !
Good morning. Awesome explanation and thanks for the vdo. If I want to buy this speaker from the speaker shop what is the Watts, Ohms and diameter of the speaker I have ro ask ?
Woow top video
Very well!
Very good speaker indeed.
Huaaaaa I want to make one!
good job
ma abonez !!!!
Sorin succes sa ai 1 milion de sub
Bravo BOSS
Thanks
Proiectul este foarte bine explicat, componentele sunt best buy la pretul asta, cat despre video... Dureaza 13:37 minute :)). Meriti mult mai multi subscriberi decat ai! Succes! ;)
nice
Caixinha foda mano parabéns.
Salut, am o intrebare. Conteaza amperajul alimentarii? Voi folosi un adaptor de 12V 3Ah, iar boxele sunt de 10 W si 4 ohmi.
amplifier keeps shutting down when raising volume. any suggestions ?
അടിപൊളി എന്തായാലും ഉണ്ടാക്കിനോക്കണം..
I want to know which amplifier is best according to you as far now I saw 3 videos of 3 different amplifiers which one should i use.
super o sa fac si eu !
bv sorin
Nice g
Noise and humming problem... What should i do now!!?
Nice work, for easier battery management use a DC/DC buck boost module ~$1 and a USB 18650 charger protection board ~$1 with multiple 18650 cells in parallel, use the DC/DC buck boost module to bring the voltage up to a constant 9 or 12v or get a lower voltage amplifier and better yet one with built in bluetooth.
hi. thanks for the feedback. that will work too. but you will loose some power, because the step up converter efficiency is not 100%. usually this method is used for low voltage amplifiers 5 - 6V. you can get 12-15V from one or more 18650 cells connected in parallel, but when the battery voltage drops lower than 3V, it will be difficult for the step up converter to get it up to 12V and 1A. the efficiency will decrease to 70% or even less. you will loose a lot of battery power. the charger will also need to be very powerful. for example to get 12V 1A from 5V at an efficiency ~80% you will have 12V*1A=12W; 12W/5V=2.4A; 2.4A/0.8 (80%eff)=3A. you need a 5V and 3A charger. step up converters are useful only for low power amplifiers. I've made a 2x6W bluetooth amplifier with this configuration and it works great. but for powerful amplifiers you need a 2A or more, constant power source.
is there any noise on sound and is there any background noise without playing anything or is there any amplifier with Bluetooth chip integer that you recommended with to the people who has more budget
hi. there is a small background noise, when the audio jack is not connected to anything, or when the jack is connected to the phone and there is no music playing. but this is common to almost all amplifier boards. I've installed the volume potentiometer to my speaker, so you can just turn it down, when you don't use the speaker, or when you unplug the cable, so you don't hear the noise. the amplifiers with audio bluetooth receiver included have an auto-mute function, when the bluetooth doesn't receive any music. that's why they don't have background noise. but is the same as turning the volume potentiometer down. I will test more bluetooth amplifiers in the future, to see which ones are better.
You can get the switches for that project from your local hardware store like the Home Depot
Can someone explan for me what 16v 4700uf capacitor work for?
Can i use 12v 3amp transformer .. and via that possible to play music and battery charge both ?
yes
Обеснил весь процесс сборки хоть и не понятно было но все-же все понял👍👍👍👍👍👍👍👍👍👍👍👍
Nice
Do you mind if you like my page too? MYZ Creates Thanks.
Do more videos so I can get more ideas about DIY projects. Helps a lot❤
Cum ai calculat dimensiunile incintei?
Very impressive . Please make a video simple bt speaker.
A problem coming while connecting this board to my speakers sound comes for 1-2 seconds and stops whenever I try to give supply to the board it play audio for 1-2 second only, I try with both battery and adopter, can you suggest me something what should I do
I never had this problem. usually I order 2 or more pieces, if one is faulty, I test the other. yours probably has a problem. what voltage and what speaker drivers did you used? try it with 12V and 2A and with 8ohm speaker drivers. when it stops it probably goes into a protection mode. but what protection...? over voltage, under voltage, over temperature, overload.... it may have a faulty sensor.
Ficou muito bom.
Can we upgrade the power of a PAM8610 amplifier by adding transistors to the outputs channels?
hi. I don't think so.
