There should be a small red sticker on the rear of the black bottom of each speaker.
I had a new pair that had a problem with the finish and when the new pair arrived about 2 weeks later I went to pack up the original pair and the little sticker off. What I'm saying is the come serial # stickers come off way to easy. You would think with a speaker in that price range they would engrave the serial # on the Dynaudio Confidence plate on the back and not an inexpensive sticker.
thanks. i saw those little red stickers but thought they couldn't be it. but i guess they are. strange.
