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.

Hi! The diagram won't enlarge. Are you able to attach a higher resolution copy?

To be clear, have you replaced the ATC SM75-150 with the ATC SM75-15008? (The 08 indicates the 8 ohm version.)

The 16ohm media broke down and I bought two 8ohm and I want to adapt them to the original Crossover

You mean the 16 ohm mid (or midrange).

Which make and model of 8 ohm replacements did you buy?

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

ATC 75-150 STD

If I tried it but it doesn't convince me at all

You can simply change the mid-frequency part of the crossover : 50uF/0.65mH - 0.45 mH/4.5uF.
