Yes the capsules have to be right next to each other in order to
increase gain.
So we are talking about the same thing it takes 6 capsules total to
make both channels. Verticle triplets are to minimize phase differnce
and maximize gain as the majority of sound in natural sound recording
is in a horizontal plane.
I did build a tight triangle configuration and it worked just fine.
That was a variation of the "Two-Sided Boundary Mic" as seen on Robs
page,

Further, Klas has extensive experience using 4 capsules per channel as
a tight rectangle and that works fine.
I have not yet played with spacing the capsules in different patterns
to make directional arrays and that is a science all on its own.
There has been a thread or two from people playing in that area here.
