I'm not familiar with your project but big cabinets can get noisy.
Thick walls plus bracing is needed. My cheap array has 1 3/8" wall
thickness throught out the design. Even so, more cross bracing was
needed. This was determined while building by using the old school
hammer trick on the cabinet - thunk - lol .. {same trick used by
Wilson Audio to demo their fancy materials - lol}, hit the cabinet in different areas and fix the problems as they happen, but you need
to start with a good plan first. Just analyze your box while
building and fix the problem spots. Don't think about it too much,
just couple the walls with wood or dowels to make the box dead.
I don't think the port placement is going to be critical. Place it
in the rear so it's not an eye sore and you don't hear any wind
noise.
