ProAc 100 Crossover tweak; Scan speak 18W/8542-00 and new 18W/8542-10 .frd and .zma files?

Hi All

I am looking to potentially tweak the crossover of my ProAc Studio 100s. Reason being the new SS 18W/8452-10 replacement drivers make the entire speaker sound too different to me. (Perhaps I am crazy.)

Apart from maybe just tweaking the series resistor on the tweeter slightly to rebalance the drivers (perhaps misguided). I was hoping someone might have or could lead me to the FRD and ZMA files for these two drivers so I could play around a little in X-Sim to see what tweaks might help make the speaker sound more familiar with the new replacement drivers.

Any help appreciated, I am 100% a n00b in these arenas.
