I'm not familiar with Camira fabrics so I have no opinion. The material we use is a type of felt that's custom made for us. It's not acoustically transparent, but it doesn't need to be. All that matters with absorber coverings is that the fabric doesn't reflect. If the fabric absorbs a little more on its own, that's fine. However, for the bass range we add a semi-reflective plastic membrane behind the fabric. This increases bass absorption while reducing absorption a little at mid and high frequencies.
