Hi all! I am restoring a pair of Electro-Voice Interface A: Series II and curious if anyone has the crossover schematic available. I am also curious if anyone has worked on these and has suggestions as to alternative crossover components that may no longer be available or possible upgrades. Thanks in advance!

I was hoping for similar I had read previously that their woofers are good to 4000hz and note those tweeters in other models have been crossed as low as 1500hz all be it 2nd ordered . I hope that helps you can see in my pic I ended up making replacements for the foam diffusers out of 5 layers of textured pvc place mats . I replaced the caps out like for like and used modern binding posts
 
The original Interface A has a cone tweeter- while the Series II models have the Superdome tweeter...

That would necessitate a different crossover, naturally...

Gordon.
