Portable Speaker with Passive Radiator DIY [3D Print]

The cashback service I recommend is - letyshops.com/...
Here comes the second part of a DIY column! It sounds (honestly) better than I expected. And 3+3W power is more than enough for such a column. There is a passive radiator on the back panel that resonates at 50 Hz and increases the audible low frequencies. On the front, in addition to the two main speakers, a high-frequency radiator is installed in the center. It allows the column to produce a cleaner sound.
