I have experience with these speakers for about 15 years, I have used them in various projects, they are the best you can get for their price and even for more, but someone needs to know what to expect from a speaker that costs around 4 euros.

Objectively, the bass for their size is very good, they mainly play from 120Hz and up but also go lower towards where their response fades, the mids are a bit muffled, highs are not particularly present, they just have some breaks in their response that appear here and there, they are like midbass, but if you consider the cost they sound like a speaker.

If they play alone they can be tiring, if someone wants to replace the dashboard speakers and also has others in the doors or on the rear shelf, they are a very good complementary solution, on their own they are quite good for their price and only that, for someone who has no demands and just wants to replace the broken stock speakers in a car they are a very good solution.

In terms of volume, they are not sensitive, you give a lot of watts and they produce moderate volume, at high volumes for their size they play very well and do not distort unless they are pushed in the bass, they do not play well with the bass boosted from the equalizer.

Expect about 101-104 at 1 meter with 64 watts depending on what they are playing..

For under 3 euros each, it's probably impossible to say anything bad. They are not very sensitive (86 db) but they play well, they have clarity, liveliness, dynamics, noticeable and defined bass (although their specifications are low at 120Hz, the bass is more than expected and it surprises a bit) and a sense of space. They don't excel in the treble (let's say that) and they probably have slightly emphasized mid-highs or the lower range of the highs. This can result, with mismatched amplifiers, in a slightly brighter and harsher sound and maybe give a slightly more nasal tone to the voice (not that it will necessarily happen, it happened to me with a micro hi-fi system that I don't appreciate the amplifier and its sound). However, what I'm saying are extreme details that don't change the image of an unexpectedly good (and quite musical) speaker, at this rather humiliating price. Price-performance ratio, excellent. But overall, I have the feeling that many people will like their sound. 27/6/19 - Finally, listening to the speakers on other systems, yes, they tend to have some sharpness and harshness and a slightly nasal sound (and a slight emphasis on the sigma), i.e. they tend to "whine" a bit in some areas of the spectrum, and indeed the higher trebles are not their strong point, but at this price and size, I don't know what demands someone can have anymore. It is the cheapest one can buy. It goes without saying that, for everything we say, we have in mind that we are talking about speakers that cost about 5.5 euros for both! S.D.
