You are getting reinforcement from the right side of your room. Have you treated the first and second reflection points for your speakers?
Test CD : In Phase / Out of Phase test
I am looking for some help with the following problem?
Many test disks will play in phase and out of phase signals to assist in loudspeaker set up
In phase – my system plays back a signal that is tightly in focus and directly centered between the two loudspeakers. Good.
But, for out of phase – where playback should have no apparent source and seem like it is coming to you from everywhere in the room, my system whilst reproducing a signal that is diffuse and not centered between the two speakers – sounds stronger from the right speaker than the left, like the right speaker is the source.
I have tried the following
1. Changing the toe in of the right speaker so it does not point as directly at the listening position. The problem still remains
2. Swopping the left and right speaker – the problem still remains
3. Passing a 1KHz test tone and pink noise through the system and measuring SPL (dB) 1m from each speaker. The measurements were identical. Taking the same measurements from the listening chair however showed a 2dB stronger signal at the right side?
Any suggestions?
