In Reply to: RE: First reflection points on the floor posted by Hifisound on January 6, 2011 at 20:37:50:
Porous absorbers are 100% efficient at frequencies where their thickness is equal to or greater than 1/4 of the wavelength. A 1 inch carpet will efficiently absorb frequencies above about 4 kHz, below that efficiency will drop, to levels close to zero in the bass region. This means that carpet or rug will not remove the reflection. What carpet or rug will do is remove the high frequency content of the reflection, which is the equivalent of turning the level of the tweeter down. Just keep that in mind.
