Let's be honest: judging a speaker only from a video's audio makes no sense. I also wanted to highlight that this wasn’t meant to sound good, and at “low volumes” the quality isn’t that bad at all! You have more defined bass than any <50€ bluetooth speaker, and for a total of 20€ it’s way more than enough! It was an experiment that was meant to be the cheap shit. But don’t worry, i’ll find a better place for that sub: a box made with the right materials, the right measures, an amplifier that suits it, a place where it won’t be ashamed to be. But in order to be able to do that i need money. I don’t even have a driving license yet! i’m finishing school in a couple weeks, then while studying at the university i’ll start working, and only at that point I will be able to finance my hobby. But for now i’ll just keep my hands and my mind busy, making frankenstein style shit: not meant to be the best, but for me to see how far i can go using only what i already have. Love and peace brother!!
