Eh, I wouldn't count that as expected unit to unit variatoin. Remember it's not just the reserve series; it's the same tweeter used in the Legend series, and this is one of only like 2 measurements I've seen without at least a bit of elevated treble. That said, this tweeter is incredibly sensitive to positioning, but as ROOSKIE said they measured several times to the same results, I take his word for it. Just some examples beyond my measurements of the R200 and L200:The difference looks like a lot on the graph, but IMO it is within the range that is possible for unit to unit variation for cheap tweeters. It's a bit of an excessive case(if the measurements are comparable, umiks can be weird in the upper treble) but certainly possible.
Unfortunately we don't really know how good unit variation is between mfgs except for some of the studio monitor companies.
Polk R350 ASR (not that elevated but still a little):
Polk R100 Erin's Audio Corner:
Joe N Tell R200 (measurements look weirdly scooped but tweeter runs hot nonetheless:
There's one more measurement behind a paywall too.
One counterpoint I found, Stereo.de Polk R600, but I don't know much about their measurement setup and I've seen them be a bit inconsistent before:
I suppose one could make the argument that we reviewers get golden samples but in my experience that's definitely not been the case.
Overall, ROOSKIE's measurements definitely seem like an outlier to me for this tweeter barring anything wrong with the measurement setup
