I have the original JBL L100 Centuries, the ones with the center of each of the three drivers on the same vertical line. This is what my foilcal looks like:

Below is a photograph of another L100 like mine with a different foilcal. The owner claimed everything was original though I'm questioning whether the foilcal is. I have never seen the original L100 Century with a foilcal like this, only the later versions. Does anyone know whether in later production runs of the original L100, the foilcal was changed? Thanks.
