@Calvin: agreed!
I had a fellow villager having a coffee at my place and we listened my stats and comared them to my fast built and cheap OB speakers (consisting of 2 Peerless 12 inch woofers per channel and 1 "full range" 4 inch driver by Mark Audio (Pluvia), but especially with one particular recording there was a huge difference in sound quality between the loudspeakers.
By the way, when just re-installing the newly coated esl, it seemed to have the same sensitivity as the other channel. But tonight I was listening some music and got the impression the newely coated esl sounded louder than the other channel. After a quick measurement I discovered the newly coated panel is 4 dB louder than the other panel. So maybe, if I feel in an active mood, I will service the other channel as well.
Just wondering: do other esl builders here experience differences in sensitivity in their stats, for instance, just after finishing them, and / or after several years? If so, how many dB?

I suggest, do it ASAP! The explored (detected) asymmetry can make a continuous discomfort - partially as placebo effect too.
