A wireless stereo speaker I build using Up2Stream AMP board.
The case is made of PVC boards I have for modeling, the speakers salvage from my old desktop speaker. I only use a 12V/2A power supply but the volume is already high enough to use in my room.
I connect it to my PC as desktop speaker when I watch videos and play games, listen to spotify when I am working on my models.
So far, it serve me very well, the sound is good.
Now I am thinking to add a rotary knob for volume control, it will be more convenient then going back to the app just to change volume.
If both speakers share the same room/space inside the housing it is essetial that they have the same polarity/“are in phase”. Otherwise the sound waves of the spaekers may vanish if they overlay.
Added a volume knob and put some LED light with breathing effect
Also seperate the speakers in different rooms as suggested by zimmer, feels like it do sounds better
