I replaced my €21 speakers with these specific ones, but I had to buy the Felix ones again. I tested each one separately, with the left being Felix and the right being Pioneer. The only thing that slightly impressed me was the volume of the sound. I was expecting something more.

I bought them to put in a professional small truck (Fiat Strada) because the speakers were not working properly. I didn't have high expectations, just wanted the music to sound decent. And that's exactly what happened! Now I never have to turn the volume up high because it's not necessary. With less than half of the volume, it sounds clear and loud. For almost 40€ that they cost, it was exactly what I was looking for, quality and decent sound.

Okay guys, the speakers are amazing.
I never expected that with two speakers worth 50€ I would make my room a club. I wanted to get the same ones for the back, but the shelf has a tilt and the sound will travel towards the glass, so coaxial speakers won't help, you need separate ones. However, they are unbeatable for the front.
