The amplifier will be good but for now forget about it until you find the speakers. Then you will have to calculate the casing for them (by inserting into something that resembles it, it will sound like a Chinese radio). You'll lose more time, money and nerves on her

You provided one module on which you want to build portable audio. And on the other hand, you ask what to choose. In turn, if you can't even measure the speaker's resistance and you don't know where to get another one, even. What are we talking about here? In my opinion, the best solution would be to buy 2 broadband speakers for this module. In small columns for home cinema there are such. In my opinion, they would be perfect. Some have very good power and efficiency and compact dimensions.

In addition, the author must determine what he wants to feed.

Right, I'm going to buy cells so that I can charge such equipment at home, so that the cells reach about 22v and 10AH, I also found some 2 bass speakers 4 ohm 30w rms 50w max

I want such a tube to be easy to carry and look something like this jbl

Mac.Gyver · Answer

As it has with 30 RMS it's a success. And the performance probably barely 80dB. Typical quinoline Not suitable. I told you to search for broadband.

And broadband is not just a fake tweet and woofer in one? they are not very popular in portable speakers.

szymon122 · Answer

Distinguish between two-way loudspeaker and broadband loudspeaker I watched this JBL, it has two loudspeakers, each has a good 10mm swing and two passive membranes on the sides, it works so well that the parameters of the mounted speakers are known and as a result the required housing could be calculated.

Mac.Gyver · Answer

There is such a solution in many devices. And then you are able to do the crossover yourself and choose the right speakers for this solution so that it sounds decently and not just roaring?

xerden10 · Answer

I will think about this, I will probably use some pvc pipe to make a tube, I also found another decent bluetooth amplifier

Mac.Gyver · Answer

And what is this module better than the previous one? The amplifier is not the most important element. The most important is the speaker and cabinet.

szymon122 · Answer

How is this in what? Instead of 30W it has 100W and apparently the author likes it, next week there will be another thread that he does not know what to power it and will be a bit surprised that playing with such power must have a car battery. For my part, I recommend PAM8403 and nothing more, the power for a wireless speaker is fully sufficient, power supply from 5V and thus a normal powerbank is enough.

xerden10 · Answer

if I want to make a portable speaker, the bluetooth module will be better to lower some PAM or TDA without bluetooth and buttons, and I did not look at watts only what the board has in addition to the amplifier, I still have to design somehow passive crossovers because I do not want to insert any two midrange I can give two tweets and 2 woofers, two-way to be the most favorable I think.
