V. PHASE ADJUSTMENT
CASE 1
A
The subwoofer is on the same level as your main loudspeakers : Phase 0°.
B
The subwoofer is on the same level as your main loudspeakers : Phase 0°.
By positioning your subwoofer in a corner (position B), you gain +3dB of level thanks
to the reflection of the 2 walls compared to the A position. To produce the best bass
level, with the deepest rendering, and very well articulated, orient the subwoofer on
the tangential axis (corner to corner) which is generally the longest axis of a room.
The subwoofer is positioned against a wall opposite your main loudspeakers : Phase
C
180°.
The correct position is the one that subjectively provides the highest and most
balanced bass level.

B
The subwoofer is on the same plane as your main loudspeakers : Phase 0°.
By positioning your subwoofer in a corner (position B), you gain +3dB of level thanks
