(Questions) Proac reference 8 Signature crossover

Anyone has
proac reference 8 signature crossover schematic??

I have proac reference 8 and I recently got seas excel 4.5in woofers.

I will install it to reference 8, so I wanna retrofit the crossover.

what is different between
proac reference 8 crossover vs. proac reference 8 signature crossover??

Any idea what to change on the crossover?
 
2 ways from Proac has often simple filters : 12 db low pass and 18 db High pass.

Look for Proac D15 filter at Troels Gravsen web, the D15 was big Signature but standfloor.

The filter is certainly close or even the same than the non signature if the tweeters are the sames. and caps already Solen MKPs. Some noticed than the Tablett reference was more musical than the signature....

I'm not sure the driver you get is the OEM made for Proac...

I will keep the reference as they are, many chance your tweak will not be an upgrade as the drivers are differents, and this scenario, the filter shematic will not help you really.
