Room Boundaries
Each surface in the room constitutes a boundary for sound; floor, walls, and ceiling. Room boundaries will reflect
sound to one degree or another depending on what their surface is made of; hardwood, drywall, carpet etc.
Placing speakers very close to any boundary should be avoided. The closer a speaker is to a room boundary, the
more anomalies there can be in the low frequency response of the system. Placing a speaker close to more than
one boundary (e.g. in a corner) creates even worse problems in many cases.
Conversely, placing speakers exactly halfway between room boundaries can over-excite fundamental standing
waves in the room, making the bass response less reliable. This also holds true for the listening position. These
room anomalies are always present and good placement of the speaker and listener will reduce their eect.
A good rule of thumb is to place speakers somewhere between one quarter and one third of the distance
between room boundaries as shown in Figure 4. Also, make sure the listening position is not right in the center of
the room if possible. In larger rooms, this is less critical than in small rooms.
Sometimes this ideal positioning is not possible. Limitations in space and other equipment or furniture in the room
will dictate some aspects of the speaker position. The idea is to do the best you can with the limitations you have.
