DBA10 In-ceiling Subwoofer Manual
The music we hear as bass is made up of frequencies that have long to very long
wavelengths (6ft. to 50ft.). Therefore, when a subwoofer is placed into a room, its
position in the room will affect the amount of bass perceived by the listener. In
other words, placing the speaker in some areas of a room will result in more bass
than in other areas of the same room. The more surfaces (walls, ceilings, floors) a
speaker is placed next too, the more bass you will hear. An in-ceiling subwoofer
mounted in the center of a wall (or ceiling) will gain 3dB of bass if it is moved up
the wall (across the ceiling) to where it is adjacent to the ceiling (wall). You can
then gain 3dB additional bass by moving the speaker to the corner, where the
intersection of three surfaces occurs.
