manifold identification/name

[indychuck]

As I delve into terms of manifold types of IB systems, I'd like to picture in my mind what is what when I read about them.

Can I have these two types of manifolds named? I'm assuming one is a dual opposing, but depending on one's perspective, either one can make a case for being a dual opposing IB.

Thanks!

They're both dual opposing, one has the drivers inboard of the manifold. the other both are outboard of the manifold.

Functionally they are identical
