need i really big reflector- kinda like 200mm?

just need a a larger reflector for big throw with 3 sst-90’s

200mm? Sh*t that's a big reflector... May I ask what you need such a large reflector for? Also, you say for 3 SST-90s, would it be okay to have 3 smaller reflectors that you could arrange in a circle for a total OD of 200mm, because I can't think of ever seeing a 200mm reflector that has such a large opening in the bottom.

yea i spose i could satisfy with 3 smaller ones :L doesn’t have to be 20cm as well. but i want a big throw and doesn’t matter how big they are.

does anyone know any 9A driver for them?

They also have a 128mm diam/4 degree smooth CST-90 reflector in the works.
