I was going through the gallery and came across Paul W's manifold and I have a question regarding this design.
With drivers on 3 of the 4 sides of the manifold, will this arrangement still cancel mechanical forces? I thought it had to be either 2 or 4 sides.
Also some other interests:
With the IB manifold being a 'hole' in the wall, doesn't this reduce (or even remove) room gain normally associated with dimensions as well as how solid/sealed the room is? Has anyone ever done a comparison of before/after ?
If the sub is crossed with a steep slope ~35hz, would one manifold perform well if placed in the front corner (or near the corner) ? The placement might not be on the floor, but more towards the ceiling.
