It's an old soviet speaker and it seems like it meant to be used in public places like gyms or shops. It had quite a big transformer coil inside, which I removed and replaced with cheap Chinese class D amp, added mini jack and micro USB socket for power
thinking about shoving a raspberry pi inside and turning it into a "smart speaker", lol
