I have this pair of speakers as new possessions. They are in perfect condition both acoustically and cosmetically. There are no traces of use or wear or tear. The aluminum discs are blemish free and the fabric cover is both intact, undamaged and unblinding.
In truth, these speakers are as good as new, you would not know otherwise because of their condition and performance.
The serial numbers of the two loudspeakers are: Type Nr: 6882 Serial No .: 19.357.634 Article number: 1.680.008 and Type no .: 6882 Serial number: 19.379.697 Article number: 1.680.008
