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 sidewalls 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 25, for further information.

Corner Treatment

It is important to control the first reflections of low frequency sound, which normally occur at the corners behind the loudspeakers. These reflections can cause significant distortions in phase and amplitude, resulting in muddy bass definition and smeared bass transients. Placing Tube-Traps (available from Acoustic Sciences Corporation) at the room corners can significantly control these bass colorations and restore the quickness of bass transients.
