Sorry but most of the "measurements ultras"
aren't able to do an accurate interpretation of the spinorama measurements. You don't consider things like the deviation between the on axis frequency response and the early reflections and so on...
You are right that a bit less smoothing can increase the score but if you go from 1/12 to 1/20 that is minimal about 0.1 to 0.2 point should be the impact.
Than it is contradicting that you on the one hand claim that the spinorama data and science behind it is that important, so no small deviation can be a good thing, but on the other hand you dismiss the high predicted preference score which is a result from exactly this research direction. So you essential claim to be better at judging a speakers tonality than the algorithm of the research you ironically praise. Disclaimer you are most likely not.
The typical bashing of speakers like Wilson Audio is kind of silly. I guess almost no one who is bashing them had the chance to listen to them at home for a longer time. You have the review of the small ones here at asr but are ignoring the good subjective comments especially with a small amount of eq it sounded very good. Some qualities can't be displayed by measurements of the spinorama and you need other measurements to show the strength of such designs like Wilson Audio or B&W. E.g. they clearly have enclosures which minimize resonances and resonances in general is the number one cause of being a bad speaker.
You always have to be aware that in the end an actual preference score from a blind listening test is the objective truth and not the predicted preference score from measurements, which try to mimic the results of an actual listening test. Haven't you wondered why a lot of the JBL speakers don't score the highest predicted preference score but a lot of these where developed so they have a better preference score so they sound better in an actual listening test.
Do you (measurement ultras
) really think the engineers at all these speaker brands are doing nonesense the whole day?
