Sure. Could you explain what this test is used to establish/demonstrate?
I would like to see if I can understand your perception through measurements.
On another note, if the perception is there, why care about measurements?
Your prerogative, of course. I trust my ears far less than pure subjectivists do, especially in the LF.
One of the world's best subwoofer manufacturers is on the record as saying that he gets the calibration results he does because he measures (iteratively). I tend to pay attention to people far smarter than I'm. And when my subjective listening experiences improve as a result of running measurements and fixing issues, I know I'm on the right track.
The typical tune-by-ear enthusiast doesn't have a UMIK or some such. So, one is limited to their subjective impressions. You do, so I asked.
Do you decide whether the sound is musical if it represents measurements well on paper?
The proof of the pudding is in the listening, of course. In the LF region, I use measurements as a tool to get to an accurate baseline, if you will. Even with 4 subs and EQ, at my MLP, the bass in my room is not as close to flat as I would like (+-3 dB from 10-80 Hz), but the closer I get to it, the more my ears have been opened.
As for mids and highs in my room, there is a demonstrated drop in decay times (I've posted the difference in my thread on room treatments a while back) which has allowed the sound to remain lively, but not harsh. So, yes, if you're looking at the right set of measurements, you can get a reasonable, but not complete, sense for the sound. Listening is always part of the evaluation, but measurements preceding it can help to a large degree.
I fall into the camp which tunes by ear and i use the Umik because i want to see which way my preferences lean if i had to represent them statistically.
I merely reverse the order of the two operations.
Also, there is a fallacy in measurements which i have noticed though i can't explain it (maybe you can throw some light on it).
I wish I could help. The FR is but one part (albeit very important part) of what one hears in the room for LF.
I don't know who Danny from GR Research is, but as for measurements and listening preferences, I'd recommend looking up Harman's multi-year research into this led by Dr. Floyd Toole. I believe their conclusions were that they are an identifiable set of measurements for loudspeakers that can predict with around 87.5% accuracy what speakers listeners will choose in a
blind listening test.
