Generally a cardioid capsule works by means of the venting to the rear of the capsule. Often it's the same capsule that is used in an omni mic, but in a housing that has that venting. I guess the Schoeps MK5 and the Shure KSM141 are examples where the polar pattern can be switched just by mechanically closing or opening that venting.
But do all omni capsules have the same characteristics to the back of the capsule that allow this?
I'm wondering whether this omni capsule can be housed such that it is cardioid:
Any thoughts?
