Avalon Acoustics AVALON ASCENDANT manual First Reflection Points, Corner Treatment

First Reflection Points

Since the ear/brain system tends to integrate the sounds arriving within a 10 millisecond time window, it is important to control the early reflections arriving from the side walls to the listening position. A hard-surfaced wall can produce a strong frequency-dependent reflection that can interfere with the reproduced sound-stage, as well as change the perceived tonal balance of the system. Therefore, damping these first reflection points is strongly recommended. Please refer to Section 8.3, Early Reflections, beginning on page 22, for further information.

Corner Treatment

It is important to control the first reflections of low frequency sound, which normally occur at the comers behind the loudspeakers. These reflections can cause significant distortions in phase and amplitude, resulting in muddy bass definition and smeared bass transients. Placing DAAD’s (available from Acustica Aplicata) at the room comers can significantly control these bass colorations and restore the quickness of bass transients.
