Is a 2.7 dB left-right stereo imbalance reasonable for a loudspeaker-room
interaction in a nearly symmetrical room?

My last system needed no tweaking of the left-right balance control to
get a central image. However my current system needs a 2.7 dB shift in
the balance control. I have checked the source balance and swapped all
components (including leads) and the imbalance remains in either the
room or my ears.

I assume this imbalance is a loudspeaker-room interaction. The room is
not perfectly symmetrical but not far out. An intruding chinmey breast
is the main asymmetry, apart from furniture.


Is this at spot frequencies, or were you using a 1/24th octave RTA with
pink noise?
