Sound below average. You can't expect much from speakers that cost 25 euros, but these specific ones disappointed me. The high frequencies are mediocre, the midrange is average, and the bad thing is that they have a large excursion in the suspension and try to play bass, which is very good at low volumes. When the volume increases to hear voices at a satisfactory level, the sound is distorted due to the distortion caused by the suspension that rattles.
A mediocre choice if your source has a crossover and you cut it around 120-150Hz, and they are not for high expectations, they easily get overwhelmed.
If you have a low-quality radio, just forget it, the volume won't go up even at 25/40 without distorting the sound.
The volume is also below average, they have low sensitivity (88db-1w-1m) and require power to play, which distorts the sound.
I don't have anything to compare them to at 20 euros, but compared to the Tele LSP-63 speakers that cost 3-4 euros each, the Pioneers play mediocrely regardless of the name.
If someone is looking for a good upgrade compared to factory speakers, this is not the solution, it's better to go for something like the MTX Thunder speakers that cost around 50-60 euros.
