The amp is also a strange configuration. the processor is on the back panel and the heatsink and coils are on the left side panel connect by wires. Very strange.
I assume it's a powered sub. The benefit of a high impedance driver is lower current requirement from the amp. The disadvantage of that is higher voltage required of the amp. But that can be a plus as well. One possibility is a transformerless power supply. So the bottom line is that the high impedance driver allows them to do something with the amp that a standard driver would not.
