Hi Arny! Sorry to be late responding but your reference paper was a tough read. And I found it unconvincing - the 3 esteemed academics started off with 6 subjective measures of loudspeaker performance that they wanted to measure, dumped 2 of them & then combined 2 more into 1, leaving 3 of the original 6! There was an awful lot of fiddling about before they arrived at their "results" based on a panel of 11 (odd number in both senses - did they dump 1 of those as well?) "experienced" listeners, & a caution that their experiment could only be performed by "experts". Outlying results appear to have been arbitrarily disregarded - if you get rid of the data points that DON'T fit your regression curve, you WILL improve the correlation coefficient. That was 'O' Level statistics back in my day. A massive number of reference papers, not explained & no doubt equally dry, & no actual DATA. They casually mention the loudspeakers chosen but don't indicate which made it to the "evaluation" stage, let alone identify the data plots. The measured frequency response plots for the loudspeakers are so similar as to suggest that the room acoustic was dominant, whatever a ITS2464 or whatever room is. I know that I haven't got one... Masses of DSP & then they suggest that they've found the Holy Grail of loudspeaker measurement. Yawn! I realise that the paper appeared in the May issue, but I actually checked more than once that it wasn't actually dated 1st April! Repeatable experiment? Not in my book...
