If I'm understanding these speakers correctly this is just old tech being rehyped under a new brand. They're basically normal speakers but replace the "black circle paper resonator disc"(idk it's real name) with a suction cup. And now you can stick it to any surface and just resonate that be to make your sound... it sounds like absolute shit on %95 of surfaces. It turns out most objects have very clear resonating frequencies and every time the speaker would play those It would be much louder making it sound very tinny.
I could definitely see a company adding a microcontroller and microphone to try and real time create an equalizer to mitigate this, and it might work and might be what was done here.
Also there is a YouTube channel called tech ingredients. The main guy like to talk long and dry but he gives out good info. He did a video where he took super cheap resinator speaks and tested a bunch of different materials and shapes of what to stick it to for the best inexpensive sound. Resulting in an amazing tutorial on how to make loud diy very high-fi speakers for about 30$
