Final tweaks

Beyond the settings for the monitors, additional tweaks may be desired to improve the response of the system
and room environment. You may discover that a reflective surface is causing a high frequency anomaly or perhaps
room modes are disturbing the bass response.
First reflection treatment
Sound reflecting off hard surfaces that are close to the listening position can cause problems in the high
frequency response and imaging of the monitors. In many cases, these first reflections are relatively easy to fix.
Figure 7 shows some common causes of first reflections in a typical control room.
Figure 7: Common causes of first reflections in a typical control room.
First reflections can be located easily by using a mirror placed on various surfaces in the studio to check if you
can see either monitor in the mirror while sitting in the listening position. If you can see either monitor in the mirror,
upper frequencies will bounce off that surface directly back to the listening position and potentially cause
response problems.
Placing absorptive material on these surfaces will reduce the effect of first reflections and improve the sound of
the system. The thicker the acoustic material is, the more effective it will be. Also, creating an air space behind the
material will improve its effectiveness. Place as much absorption that is practical at the first reflection points to
improve the response of the system.
Bass room modes
If you notice any peaks or dips in the low-frequency response curve of the RTA (20-250 Hz), they are probably
