That is pretty bizarre. My RCA filters definitely show just what I posted above, and it seems to completely disagree with what the photo in your referenced ad shows.
I also have a set of XLR filters, and they read something entirely different from either of the two RCA examples.
I am not sure what you should do, other than measure the voltage output at the speaker to verify (the Vandersteen manual does a nice job of explaining that process). Then you will KNOW your are getting the correct roll-off.
