This is why I'm always a stickler for consistent scaling...
But those measurements simply do not line up under any stretch of the imagination. Like, either something went terribly wrong with Soundstage's review unit, or Heavenly Soundworks is being incredibly disingenuous. No amount of smoothing can reconcile these measurements.
Heavenly Soundworks' in red, and the NRC's traced in blue. The dotted blue line is the NRC's measurement again, but with the strongest smoothing REW offers, 1/1 octave:
View attachment 122092This is the same scaling I use in my reviews (vertical axis is 25dB, but the scaling is maintained). Not even 1/1 smoothing brings the measurements close to one another.
Honestly, the measurements are so far off I have no idea what's going on. It's hard to imagine Heavenly Soundworks would even dare send its speakers to soundstage network if it knew the results would be so off.
Directivity looks solid, at least, though without normalized measurements that's a bit hard to make sense of with an on-axis so ragged.
