Time to kill the myth that "flat" bass is "correct" bass. in Bass Gear Posted March 12, 2017 · Report reply Here is a link to a Harman study about target curves.Hopefully it will work. Thanks for the link. I've read this and the auto EQ vs the "target FR" articles in the past. I compared (one of many that have changed with remodels and changes in hardware over the past 15 years of measuring in-room) my response at the LP to the results of the auto EQ article. 1) One guy preferred the low end bumped +15dB (IIRC). 2) IMO, 1dB/octave, which amounts to (+/-5dB) is tantamount to a flat response without EQ post smoothing, which I don't use. 3) My high end is bumped because I've lost a chunk of hearing capability up there, but I don't find a more rolled off high end objectionable. 4) I listen at significantly higher playback levels, which alters perception. Any test should use only program where the mix level is known and matched. 5) A noted caveat in the auto EQ article is: "Program material is a nuisance variable". 6) The results of all of Harman's studies leave out the fact that they reveal a simple conclusion; a) either the producers of the selected program source had seriously flawed monitoring hardware or b ) they really sucked at mix production. 7) Playback systems that roll off sharply below 50 Hz shouldn't even be a part of a listening session of any kind, IMO. 8) All of the hardware used is a Harman product. 9) Sine sweep FRM graphs are always the metric used. Reminds one of "listening tests" over the past century: Was Edison serious, or was he selling his invention? Note that some of the "listeners" have the blindfolds covering their ears!! Also note that they are all old guys whose hearing might be dubious. Acoustic Research conducted many "listening tests" comparing "Live vs Playback": WUT?? If I post the Ground Plane measurements results of the Raptor, someone please predict what will happen before the virtual ink is dried? This "test" cracks me up. It seems the principals got the wrong memo on which of the human senses were being tested? Preferences don't mean much and the industry should get that and move on. Nothing against any preferred curve, just that proclaiming one a "target" over others is just silly. Members are appreciated for their posting efforts, especially guys like SME who have interesting stuff to post. But, edicts such as "your method is BS because Harman said so" should expect some blowback.
