If you're trying to figure out how it works cut the cone off of a subwoofer 🔊 and mount the voice coil up against a box or table or anything and it'll create acoustic resonance and basically move air with out needing a big box
I wish you played the speaker on the cardboard box and fed it more and more power so we could see how loud it got. Isn’t that kinda the point of blowing up speakers?
