When located by a wall (half space), power output will increase by 3 dB (see
Figure 4) when compared to placement in a free-field environment (see
Figure 5). When located at the junction of two walls (quarter space), power
output will increase by 6 dB over that of a free-field environment (see Figure
6). Finally, when located at the junction of three walls (eighth space), power
output increase a full 9 dB (see Figure 7).
It’s not always possible to utilize walls and corners for extra power. The
nearest wall or corner might result in the subwoofer being positioned behind
the microphones, causing feedback, or, too far out of time sync with the full-
range speakers. Sometimes the sound quality from a subwoofer located in a
corner is not desirable due to other aspects of the room’s acoustics.
However, when wall and corner positions are appropriate to use, they offer
a tremendous increase in power output.
