I've just destroyed a Samsung surround sound speaker. I was surprised by what I found inside. The bottom unit appears to be a passive radiator but its surface area is only the half the size over the main drivers. The speaker has a passive high-pass filter at about 1Khz.
Is this a gimmick or is there any method to this madness?

Which model of Samsung? Picture is too small.
Which driver is midbass and which one is mid?
To me it appears as regular D'Appolito two-way with two midbass drivers and no dedicated midrange driver, with one passive radiator for both midbass drivers.

Did I mention that I took it apart? After the input there is a 2nd order crossover with a 0.35mH coil and a 3.3mF capacitor. The 'bass' signal continues to another crossover with another 0.35mH coil and 12mF capacitor. There is no low frequency signal going to any of the drivers.
Just to be sure - both mentioned filters are high-pass? With the first element of the filter (closest to the amplifier) 3.3uF capacitor (or 12 uF) and after that 0.35mH coil parallel to the "mid" driver?
The first 3.3uF filter is a crossover, the high signal going to the tweeter. The low signal continues to the second filter 12uF, the high signal continuing to the drivers and nothing connected to the low side.
