Default Transformer bandwidth

I have been planning my ESL project and have wondered what is the maximum bandwidth one should consider for the matching xfomers.
I am thinking of building a LM3886 or 4780 based amp for each LF,HF transformer. Xover, phase and amplitude will be controled at the amps input. ESL panel will be a large area full range.
Dynamic driver for sub.

Looking at the MK121 interface schematic it appears the two bands overlap. There has to be a better way of doing this.

Just tossing around ideas at this point.
