HF sound doesn’t need a big space, the wavelengths are quite short, so the tweets flowing out the bottom seems logical. The horns will control dispersion somewhat, and possibly add efficiency (not much really), plus essentially they are there to change the direction of the sound.
Also re: getting mics to work while sound is blaring, that’s the easiest part to conceive of how to do. Since the sound is digital and it knows what’s playing, it should possible to “subtract” that sound from the incoming waveforms from the mic(s) in real-time, so it can “hear” you no matter what is playing or how loud.
the oil is probably ferrofluid to cool the tweeter and improve it’s magnetic properties
