If you want real small, and have the budget for the drivers, the ScanSpeak 10F-4424 fits into an even smaller miniOnken… these do lack both top & bottom but are very smooth.

You may not know, but all recording studios have a pair of small speakers over their consoles, and play the mixings on them at the end, to have an idea on how the audio will sound on a car or similar. The drivers are small and the sound is good.

The major problem is the box, really, I think.
I know about mixing... done some in my time and yes, we would actually bring the mix to the car radio to check it.

Then, I'll say it again, you will not beat portability and sound with any kind of DIY you can come up with.

I have a friend who has the Bose Soundlink Mini, and it would probably do well in your case, or something similar.

Easy to go to a store and have a listen.

Sorry, no Bose speakers sold in Brazil.

Most small commercial speakers sold now have Bluetooth interface, which does not serve my purposes either.

Would be a lot easier to give suggestions if you would give some kind of budget and size criteria? I know that portable are small, but are we talking 2 liter or 4 liter enclosures?

Those Bluetooth speakers all have a DSP on board and are tuned using measuring gear (calibrated microphone). The DSP is dynamic and adjusts bass based volume level. Unless you can do the same, you cannot beat them. Many of them can be connected to an audio source with a line in cable. Production in numbers makes their price lower than you can build it for.

One liter would probably be the largest. Remember the idea is to put the two speakers on the bag along with clothes and all.

Driver size is probably around 3", though of course most of them rely on a large box to extract some bass from them. Which is not possible in this case, and might demand active eq for extra bass. A parametric filter before the amp could work fine.

Budget might be $100 tops.

Something you could carry around when traveling. It can't be too heavy or big, as it should fit easily inside a traveling bag.

Any suggestions?
Ok irmão, then go measure your travelling bag and tell us what is the acceptable size

Consider a pure rectangular cabinet (which you can build) and not a plastic rounded edges one (which you can not) which makes it a little more difficult to fit inside a travelling bag.

No, "Tupperware" type plastic food containers are not suitable for this (I tried) , walls are too thin, too flexible, not braced, and vibrate way too much: unusable .

If anything, plastic tool cases are better, (I tried), and worst case they don´t need a bag for transport, they are self contained and even have carrying handles

maybe you find a size where 2 of them fit inside your bag, but in any case we need your data to be able to answer.

I bet a couple such cases, sporting, say, a 4" or even 5" full range speaker, and one housing, say, a 30+30 to 60+60W amplifier, maybe Class D and with an SMPS supply to save weight, will be immensely better than those 2" TV speakers, any day of the week.

I have built small Guitar and Voice amplifiers inside such cases (as well as powered mixers to be used with external speakers) for travelling Musicians, even with built in rechargeabla battery for street/subway performers, go figure.

Or you can build a lightweight box, any size you want, out of 12mm plywood, even down to 9mm if you are (or can get) a somewhat skilled carpenter.
