How important is it that the front of a porous absorbent is air open?
In descriptions of how to build reflection traps with porous absorbents, it always says that the front cover should be air transparent. Is it really necessary? As long as the front cover is not too heavy and mechanically connected to the porous material, the sound waves will go straight through, anyway?

If you place something in front you will range limit the absorber. The mass and size will determine cutoff freqiency. Do not do this in a first reflection point.
