Hi, yep those are midranges, custom made to Wilson Audio. Ataching measurements I made in 2010 vs stock driver of scan speak (same measuring conditions, 1V input at 20cm, normalized to 1m/ 2.83V input)

can you please elaborate on Scan Speak 18W8530K00?
I cannot find any 4Ohm version.
Was that custom made and you recoiled it with 8Ohm coil?
That requires refoaming/reconing as well? Do you have any measurements of these drivers?

they are coated cone of scan speak revelator 18W. they were "born" as 4 ohms versions form factory, but in ~2010 speaker design I needed 2x 8ohm in paralel= 4 ,so voice coil was replaced by original revelator VC just 8 ohms instead of 4. I can make measurements. they are not differs from stock and could be used any any designs that require 18w revelator 8 ohms.

the mids was 12m revelator, and tweeters 70005
