DIY 20W Portable Bluetooth Speaker - Homemade

I made a 20W bluetooth with one 3 inch passive radiator. The bass test at the end of the video was at maximum bass with 90% volume. One of the speakers is probably broken towards the end because of it. Not noticeable though.

nice work looks simple but good at the same time

Thank you

A ported speaker box this size might sound well also. I have a diy speaker that was made out of thick illustration board similar to that size, but using a bass port instead of passive radiator, and a little bit of tuning in Poweramp eq and it sounds very comparable to branded speakers.

[@TaylorSoloaiJR]

I have done some experiments before using ports but never sounded good to me. I'll have to do some more experiments using them.

Bro u cannot simply port it just by porting it. This needs calculations with Thiele Small parameters and so on.

Try make another speaker with pringle cans

[@MJ-Quema]

Put some vinyl or paint on it to make it better btw what's the speaker model

[@TaylorSoloaiJR]

I tried looking but it doesn't have a model

Wow 😮

[@GalaxyYT.]

where do you connect the charger on the BMS

[@TaylorSoloaiJR]

P+ and P-

[@GalaxyYT.]

@@TaylorSoloaiJR Ok, thanks! how can you like connect the 3S battery to the points with the voltages (12v 8.4v) or something like that?

[@TaylorSoloaiJR]

Hard to explain but I'll try to make a video on how to assemble it.

[@sanjo2010]

Is the jbl go still good in 2024?

[@TaylorSoloaiJR]

Certainly, but the battery is what troubles me. It's not easy to find a replacement for those.

[@GalaxyYT.]

Where can I buy the battery? (I can't use shopee sadly)

[@TaylorSoloaiJR]

I salvage mine from a defective laptop battery. Only used the good ones.

[@GalaxyYT.]

@@TaylorSoloaiJR Have you ever bought any batteries from aliexpress or other resellers? I'm looking to buy some since I don't have any batteries of those kinds at home.

[@GalaxyYT.]

@@TaylorSoloaiJR And if I understood correctly, you charge those batteries with the BMS with 12.6V and 3A through the barrel jack?

[@TaylorSoloaiJR]

I haven't used any of those platforms to buy batteries or anything at all.
But depending on where you are at you can actually get defective laptop batteries from computer shops. If you're lucky they might give it to you for free. I have to pay for mine but still affordable.

@@TaylorSoloaiJR Alright.

early!!

[@assawinsaengpratum7610]

is not bad but is too much distortion

[@TaylorSoloaiJR]

You can always lower the bass, that was just a demo on what it sounds like on max bass.

[@sakibsarwat5064]

@@TaylorSoloaiJRyes this amplifier does this in max volume especially when powering with less than 18 volts
