I agree. It looks like he has the positive and negative reversed so his left 2 speakers are 180° out of phase. Was the very first thing I noticed. Having them this way will cut you out put in half.
In this work separate left and right Chanel .. what i am trying to say that.. you are giving output of one amplifier circuit to one side of your bar where both left and right Chanel are present.. so try to take 2left and 2 right output and connect them to the respective side. And keep the polarity in mind other wise no stereo and distortion will spoil your work..
It looks like speakers connection polarity is wrong: obviously speakers move in different phase and passive radiator doesn’t move at all (although the latter could be because the box is not pressurized )
passive radiator is not moving which means there is air leakage, which means bass is not great. you should seal the box properly with hot glue to increase the depth of music
some concerns for the speaker quality: - enclosure wall thickness is too thin might cause rattle or cracks from the speaker pressure overtime -not to sure but I think 1 small passive radiator isn't enough to cover 4 speakers that size - I think there was a mistake with the wiring since the speakers are not really in sync (from what I can see in the first clip)
passive radiator not move because no pressure inside box. this happen when some speaker polarity connection is wrong. positive and negative at the same time
Amazing Bro Mujhe Pata nahi tha ki itna achha Speaker itne saste me bana sakte hain agar pahle pata rahta to main Boat ka kabhi na leta 😭 Great Sir❤️❤️
Unscientifically made...There should have sufficient distances between all speakers... However I appreciate your talent and skill in making a beautiful mini sound bar
I'm building my own and I feel I had this problem. I'm just using 2 speakers and 2 passive radiators and I could not figure out why it sounded like crap. After reading your comment it makes total sense! Thank you very much!
next time use a bit powerful amplifier circuit because pam 8403 only 3w in a single channel otherwise a verry neat and clean job appreciate your work bro
Hey bro I am making that In my winter holidays btw u could have kept two speakers front and two in the back it would be good but still ur the best bro But I am 14 year's though 😅
Assembling those speakers component are piece of cake, the only thing problem is how to make the box nice and tidy. Not an insult, i just made my shitty box. ✌️✌️✌️
@@gauravmalik3843 yes, we really do. basically it converts 5V into 5V, but the output has no electrical connection with the input. try without it, you will get a horrible interference sound. but with it, everything is OK. of course it requires you to remove the 7805 regulator from the bluetooth module (if you use the one in the video) or at least cut its legs and make sure they won't make contact with the board anymore. then connect the two spots those legs were on together. when this is done, your bluetooth module requires 5V instead of 7-12V. then use a normal converter to convert the battery voltage to 5V, and connect it to the bluetooth module via tha isolated converter. link: www.ebay.com/itm/1PCS-B0505S-1W-DC-DC-5V-Power-Supply-Module-4-Pin-Isolated-converter-NEW-Z3/173366003622?hash=item285d6b47a6:g:j0gAAOSwpmNbI3pP I CAN GIVE A SCHEMATIC IF NEEDED
Its so hard to tune passive radiators. I made a small bluetooth speaker and I placed the amplifier right behind the passive radiator. Box have to be airtight seal for passive radiator enclosure, you have to put small weights on radiator for tuning, so its really trouble.
@@SaptarshiSikder я думаю, что каждый может писать на своем родном языке, так как перевести комментарии очень легко. А так будет понятно, что твои видео смотря по всему миру. И не будет теряться оригинальный смысл теста. Видос у тебя хороший. Показываешь , как из ПВХ при помощи цианокрилатного клея и доступных комплектующих с АлиЭкспресс быстро и дёшево собрать проект выходного дня. Колонка получилась интересная. Меня лишь смутило, что не двигается пассивный диффузор, работающий в качестве фазоинвертора. Это значит что некоторые динамики в противофазе. Вот и предлагаю поменять местами плюс и минус выводов динамика.

What an insightful post! Thanks for enlightening us.
Glad you enjoyed it!
Huh! Read the top comments , its a shit which sounds really worse !
👌👌👌👌👌😊 nice
Thanku
It looked like the speakers were phasing. Check connections
Because the speaker conection here is : left, right, passive radiator, left, right, has to be left, left, pasive radiator, right, rght

Yes you are right
Bro i have a suggestion for you. You can make this speaker with 1 subwoofer so it can sound good. Anyway its pretty good.....
Thnx bro

Did u see that two speakers are moving forward and backward i think problem in amp and box also,ported box will make better sound

the left and right speakers must have their space. otherwise, there is a large distortion between channels..!! this construction is not good...

Thanku soo much bro
Saptarshi Sikder welcome and keep growing bro
Good idea
Dear focused camara on passive radiator to see bass radiator are moving are not ???! 🙏👍
The passive radiator isnt moving, because he didnt seal the box properly
Hey bro I am making that In my winter holidays btw u could have kept two speakers front and two in the back it would be good but still ur the best bro
But I am 14 year's though 😅
Cool idea
Bro where did u get the passive radiator from link pls?
i get it from old scrap speaker
Passive radiator ka link nai mila... Kaha milega? Btw nice and clean build

jangan lupa di sentuh speakernya agar daun speaker bergetar... lucu sekali konten anda😂😂😂
The 2 right drivers are out of phase
Yupp ...they are reversed polarity
I subscribe your channel after watching this excellent video keep it up bro
Thnk u soo Much bro
Bro what's your village what state

Plz provide circuit diagram
The passive radiator is not moving so just check for any air leeks.
Hey messed up the polarity of one of each speaker pair
the passive radiator is for no use because there is no hole for air passing
Bro i like it but add one subwoofer for bass
Can you tell which wire have you used to connect the pam to the Bluetooth panel plsss
And what's that beside the red switch?? ( the white thing) ?? )
strip rainbow wire

You have to use isolated converter to power bluetooth receiver otherwise it makes a very bad interference sound!
Aisa bi hota h kya bhai?
@@gauravmalik3843 i only understand English, sorry. I can make a schematic for you if you want. Use google translate if needed!
Sorry...i was asking that do we really need isolated convertor for this?...and what is it ?
As i am working on a same project and if this does really help then please tell me how to do that.(isolated convertor thing)
