Frank corrected me that the acoustic coupling was not improved with the legs changing around 500 Hz. The measurement in comparison was not equipped with acoustic box yet. So I compared the measurement with the result from psl:955 , and there is no improvement around acoustic frequency. This means that these peaks are really from acoustic coupling through air, not legs.
