So this is for PA use? Would go with the higher crossover freq to be safe. The woofer should handle that ok.
Maybe someone familiar with these drivers can jump in.

Do you plan for mono or stereo PA?
You would need a four channel amplifier for stereo.
Also the DE111 would want a steeper slope than 6DB/Octave. You would want something using an active filter for the crossover rather than a single capacitor passive.
Maybe provide more information about your speaker choices in this case.

i think if we get into crossovers too much this could divert the thread.
I’m guessing the answer to my original question (which has been answered in this thread) is out there anyway.
Just conscious of not clogging the forum up.

Another angle about power in passive versus bi-amp is you would usually have to pad the DE111 by 6DB to match the woofer. This is throwing away power on the high side unless you use a transformer in the crossover.
Also you have insertion loss in the LF side which is avoided.

As usual, Rod Elliott covers the subject well.

No, it is not. The power of each amp stays with that amp. It is not wasted as it is not being generated. You hav3 a maximum of 125 watts sent to the woofer and another 125 watts sent to the tweeter. In reality the tweeter uses much less power than the woofer but the excess power is not steered to the woofer it is just not generated by the tweeter amp. If you are doing a stereo setup you can use a smaller amp on the highs with no ill effects. The 50/50 power point is around 200hz to give you an idea of how it’s broken down. If you crossed over at 200hz you would need equal sized amps but the higher the freq of the crossover the less power the high amp needs.
If the efficiency of the amp is consistent regardless of output power then this may be true. If a 50w amp has the same idle power consumption as a 500w amp this may be true. I believe most amps won't meet these conditions though. However I'm guessing Peter was just referring to the fact it doesn't make sense to buy a 1000wpc amp in order to power a 50w max driver.
