Proac crossover

Hello, can anyone help me .
I have a PROAC EBS and I have replaced the ATC SM75-150 medium with an 8 ohm medium.
I have done some Wilmslow Audio crossover but the result is worse than leaving it original.
I just want to modify this part of the crossover the ATC SM75-150 that comes from 16 ohm and put the new 8 ohm.
I include the original diagram.

Did you try the modified version provided by Dissi back in January 2017?

ATC 75-150 STD

Would the 47uf capacitor have to be exchanged for one of 50uf and the inductor of o.56mh for o.65mh and the one for 0.68mh for 0.45mh and the capacitor of 15uf for 4.5uf?
If you wish to follow Datsun's suggestion, then this is correct.

However, it will make a negligible difference if you use the following standard values of capacitor:

For 50 uF, you may use the standard value of 47uF.
For 4.5uF, you may use the standard value of 4.7uF.
 
The new component values are chosen so that the 8 ohm midrange operates over the same range of midband frequencies as the original 16 ohm midrange.

All the components work together to produce the result you requested. The 4.7uF does not work in isolation, so will not introduce sharpness.
