One pair of new Manger 8-ohm neodymium black drivers for sale. The drivers are unused in their original packaging. I had designs to actually use these, but am forced to admit I simply don't have time for this project. The plastic face of the drivers is showing a discoloration of sorts. I have no explanation for this, and do not know if it affects the drivers' sound. I suspect it doesn't. It is not mildew etc. The drivers have been stored for about two years in a dry environment and double-boxed. The first US$200 takes the pair.
