The location of the front loudspeakers relative to nearby boundaries will excite various room modes (a complex pattern of standing waves with associated peaks and nulls), which will affect the bass response of the loudspeakers. Generally, placing the loudspeakers closer to room boundaries (particularly corners) will increase the bass response. Conversely, moving the loudspeakers away from boundaries and corners will reduce the bass response. Due to the complex interaction of the loudspeakers with nearby boundaries/corners and your listening position, significant changes to the bass response can occur with very small changes in either loudspeaker location or listening position, so experimentation with both placement and listening position is recommended to obtain optimal results.
