Here for the gear

Right now I wonder if a back wall full of VPR's would perform equally. Looking at the absorption coefficents from Fraunhofer it should, but most measurements of VPR's here at Gearslutz don't look that good under 50 Hz. On the other hand I never saw a SBA with VPR's at the back wall. Maybe I just have to try it out.

Here is another visualization of the porous absorber.
