Dhaan,
Please, read my answer again. What I wrote before is that the WB's ACT cabinet uses a sandwich of composite materials w/ a high density foam core.
The ACT's cabinet is made of an internal layer of fiberglass, a high density foam (Last-a-foam) core material and an external layer of carbon fiber. What sounds-real-audio is trying to explain you, is that the carbon fiber will add rigidity to the enclosure while the high density foam will absorb unwanted resonances very fast. That is why you cannot use a thin metal sheet to replace the carbon fiber as you asked. The ACT cabinet is not just made of a thin rigid layer of carbon fiber, which would not absorb the sound, but layers of different materials. The overall cabinet thickness is around 13mm.
In my opinion, for such a small footprint the ACT's have, the unwanted resonances are very well controlled.
Thank you.
