Kijanki, I’m thinking that what looks like the "spider" of a speaker driver at the front of the large assembly at the rear may signify that there is a large passive radiator somewhere. Perhaps the very large dome shaped surface behind the front surface and the three drivers is a passive radiator. It’s hard to tell, though. Also, the crossover network is presumably within that rear assembly.
