Alternatively you can use the protection capacitors as part of the total filtering. This way, the prot cap can be much smaller.
For example, instead of 47uF, you can use a 4.7uF cap. Just measure the driver response with the cap in place, then flatten this response at least 1 octave past xover point at the low-end (and as much as possible up top if you wants a flat response), then apply your desired xo slope. Done.
