1/8 Space

When a speaker or sound source is placed in a corner so it is near three surfaces (like the junction of two walls and the floor), it is said to be in 1/8 space. This is similar in concept to half space (up against one wall) and quarter space (at a junction between two walls). When sound sources are placed near surfaces in this way, more of the energy gets forward into the listening space (see half space for more info). Putting a source into 1/8 space yields an increase of approximately 3dB more sound power level than quarter space and 6dB more than half space.
