towards the listening area. You will notice the tonal bal - ance and imaging changing. You will notice that as the speakers are toed-in, the system becomes slightly brighter than when toed-out. This design gives you the flexibility to compensate for a soft or bright room. Generally it is found that the ideal listening position is with the spe akers[...]

10 Setup and Placement The Extra “Tweak” This may be useful when your speakers are placed in a dedicated listening room. Use the following procedure fo r your speaker’s placement to see what can happen to your system’s performan ce.
