One other thing and it is remote but may also contribute to the lesser sound of one side and that is the placement of the speaker. You might have one side that is more reflective than the other. This would be like a window or slidng door by one speaker and a wall or a large book case along a wall on the other side.
These are just things to consider and I am sure you have looked at this too.

Hi Jeff,
Thaks - yes the first thing I did was swap the speakers, to rule out (a) differences originating in any upstream components and (b) effects of the room. My impression is that the wekness travelled with the speaker.

The best way to verify whether one panel is weaker than the other is to play mono pink noise and it will be apparent where the image comes from as to if one panel is weaker than the other. This may also be in a certain frequency range, so also play pink noise in only one channel at a time and see if you can hear a pitch shift between them. Hope this helps.
Aha - I was hoping for a tip like this. I tried listening to sine waves, but it's really hard to tell, because the phase effects of the room make the amplitude very dependent on exact position of the listener's head. Pink noise could be helpful. I suspect that the weakness is only in a certain frequency range, not overall. Thanks.
I'll try vacuuming and then maybe giving them a little shower.
If it seems like just a certain frequency range is weak, is it still possible that this is linked to the electronics and not the panel itself? Anybody have any theories on what would cause wekness in a particular frequency range, either as a fault in panel or electronics?
Thanks to everyone for all the great comments so far - I very much appreciate all the help.
