I have noticed someone suggested in a popular audiophile forum that the replica cannot possibly produce the same sound as the original due to differences in steel sheet thickness and the quality of material used, to name just a few. As for thickness, I can assure you that the replica's margin of difference is the same as that found in three original horns. I measured the thickness of the three original WE16A horns with a micrometer which can read up to 1/1000 inch. I have possessed the left gauge from a long time ago. But, the mouth lip of 16A horn body is 2 inch wide. It turned out that the left gauge's throat was not deep enough to measure the thickness of the horns. So I bought another micrometer of the right and measured the thickness of the steel sheet of an original 16A horns up to 1/1000 inch very precisely. The replica is made with exactly the same thickness as the original. As for the quality of the original steel sheet, the carbon content of the steel sheet is t...
