Finally, I listened to them on another micro hi-fi system, where they played much better, with full sound, better bass, and much less, within reason, booming and muddiness, so for such a low price, they are good. Now I need to listen to them with different cables to see if they play even better and earn another star, which they may already deserve based on how they performed on the second micro system I tried them on.
---------------
FENTON is the brand and they are 4Ω. They could have been decent for their low price (although the tweeter had a weak presence, meaning weak highs, but at least not harsh and fatiguing), but the bass booms in certain frequency ranges (upper bass, low mids - call it what you want) to the point where it becomes annoying.
However, this behavior was present on a specific micro hi-fi system, where other regular (meaning not extremely low-priced) speakers did not boom.
When I connected them to a regular good amplifier, where it is ridiculous to use them, I did not hear this booming and the sound was balanced within their capabilities. I don't know if they are worth using with an extremely cheap amplifier as a temporary solution. I will try that as well.
However, don't expect to find real bass, volume, body, musicality, highs, and clarity, beyond a relative balance (which they try to achieve, unlike the 170.172 models that try to provide something impressive in their sound and not balance), just to fulfill their purpose without major flaws. Their price is very low to expect much more than something annoying.
But the issue remains that in one micro hi-fi system where I tried them, something that should suit them logically as a usage, I didn't get good results, as I mentioned before, for some reason, which didn't seem to be a real problem of the speakers when they played on a regular amplifier. So, I'm not sure about my rating (which was influenced by their poor performance on the micro system).
I will try them on another micro system. If I can do that test, I will write my impressions (which is difficult, of course, because micro systems usually have specific connectors on the main unit and not even spring clip terminals to easily connect your preferred cables and speakers).
However, if I forget how they played on the micro system I tried them on, I shouldn't give them 2 stars considering how cheap they are (the price is a joke, meaning it's a question of whether something better - and how much better - can be found at this price), but on the other hand, who would use them? They can't be used in a decently priced stereo system. If I listen to them on another micro system and they sound good... okay.
