great username; would register again
I may get mine changed to FuzzyShitSandwich®. Gonna think on it some more.
It’s a very familiar posting style. Auspicious timing too.
Specifically, his choice of mic position is guaranteed to produce data that is at best only vaguely related to what the speaker does at normal playing/listening distances. His lack of understanding of relative arrival times of the sound from LF and HF sections - and the effect of those times on response around crossover - is evident in his description of the decision-making process he used to decide on the mic placement.
You would have to have some basic acoustics knowledge in order to be able "ascertain for yourself." Were you in possession of that knowledge, you would have understood the above and "ascertained for yourself" that his data is not valid.
"Electronics work" is a completely different kettle of fish than loudspeaker testing and measurement, a fact that has bitten quite a few EE types on the ass.
Here you go. Here are response measurements of the exact same speaker, one taken with the mic 1" from the grille, on axis (centered on the speaker cone), the other taken at a distance of two meters, also on axis. You think these two responses might not sound the same? Spoiler: they don't.
I've only been doing exactly that for the past ~17 years on various gear forums, including the original and current FAS forums and TGP. I shared the data I presented above more than once in the recent past, as well as comparative clips demonstrating the sonic differences, and I've explained near field/far field discrepancies many, many times. A little searching and/or asking around would have gone a long way towards finding some of that content.
A number of the students at loudspeaker workshops at which I have taught remarked at my ability to explain complex concepts in ways that non-technical types could understand.
Not at all. The friction I've encountered has mostly been from technical types who overestimate their understanding of acoustics.
There are folks that chase tone, I am not one. I like things that work well fitting my work flow, and sound good. The Fender FR-12 sounds amazing. I was using a Friedman ASC-12, which sounded good, but the FR-12 blows it away. And an extra bonus, the FR-12 is 1/3 the cost! So I sold my Friedman and bought two FR-12’a and now have stereo!
I am one of those EE’s I guess. Bottom line for me, I don’t care about graphs and response curves WHEN my ears say it is pleasing. I am the only one I have to please!
Guessing he wasn’t ready to eat one.
