    In a 7.1-channel system, where two additional S4Ai speakers may be mounted in the rear wall, the positive phase arrays for all speakers should fire toward the rear corners, as shown in Figure 11. Thus, the side left speaker should be configured with its phase switch in the IN position, and the speaker on the right should be config- ured with its ph[...]

    20 Standing-wave energy tends to be concentrated in the corners of rooms, which is why placing a subwoofer in the cor- ner tends to increase its bass output. Because of this, it is possible to break standing waves up somewhat by “break- ing up” the corner . This can be accomplished by placing a column of thick, absorptive materials in the corne[...]
