Room Reflections - Lexicon CP-3 Plus Supplementary Manual

CP-3 PLUS Digital Surround Processor
Room reflections cause blurring of the image of a localized front sound-
stage. Sounds which are ideally perceived as coming from the screen, reach
the listener from other directions, spoiling the illusion. These unwanted
reflections can be eliminated by placing absorbent or diffusive material at
the point of reflection. To maximize the localization of the soundstage, an
attempt should be made to deaden the area immediately behind and
adjacent to the front speakers.
Speaker alignment is important. If front speakers are placed at unequal
distances from a wall, the tonal balance between the two speakers will
change. This is particularly important in placement of speakers in the front
of the room where sounds should pan realistically. Care should be taken to
place speakers the same distance from the front wall. An attempt should
also be made to achieve approximate symmetry in the distance between
each of these speakers and the side walls. In addition to being placed
consistently with regard to room surfaces, the front speakers should be
placed well away from side walls.
Room reflections interfere with the image
of a localized front soundstage.
These unwanted reflections can be either
absorbed ...
...or diffused.
