You are bi-amping, but its passive and not active.
The two amps will be amplifying the entire frequency range given by the source and outputting it to the speaker, then the speaker filters those frequency's in the crossover for the appropriate dirver. Problem is that those frequency's is just wasted power as it is all thrown out in the end.
For eg. The low pass filter will have wasted power amplifying all frequency's roughly above 2khz, the high pass filter is wasted the same way with all frequency's below 2khz. (all depends on crossover but its just a example).
Active bi amp has that same filter but before the amplifier stage so to ensure the hi pass and low pass amplification only does its job in the required frequency range, thus the need to remove the internal crossover from the speaker.
People believe that doing a passive bi amp is not worth the trouble and i believe they are right but it still can improve on a single amplifier but there is a lot of wasted power to answer for and would easily be better to just buy a single more powerful amplifier.
