I realize that a weighting factor of 2 is a conservative estimate, but I wasn't aware research on the subject had been carried out. I would very much like a summary of the paper. Unless it's of interest to MZKM, maybe another thread would be more suitable.

True, that's why you want to start out with something simple like multiplying by 2.

Penalize positive deviations twice as hard as negative deviations using the average level of 200-400 Hz as the reference band.

The directivity graphs posted by @MZKM in post #2 show how the speaker performs off-axis at different angles. If you turn the speaker upside down, my guess is the treble response would be affected by a magnitude of about ±0.5 dB. The bass and midrange would be unaffected by the horizontal shift...

The regular blue is the 3rd harmonic, which dominates THD. The 2nd harmonic is dark blue and hovers around 1% from 30 to 40 Hz, whereas the 3rd harmonic is off the chart.

Yes, it can drive pretty much any headphone. Without doing the math, I'd guess you wouldn't need to go higher than medium gain.

No need for eyeballing or guessing. These stats have already been calculated by @MZKM :) 1) https://sites.google.com/view/speakerdata/preference-ratings-graphs 2) LIST 3) Revel F328Be 4) SPL Specs: -3 dB = 67 Hz -6 dB = 48 Hz -10 dB = 34 Hz

If the error is approximately 1 dB, as you mentioned on page 13, I'd say it's time to move on. Even if this model had 1 dB more bass, it wouldn't change the fact that it's a bass-light speaker.

That's just how the autogenerate function in REW works. Nothing wrong with it in theory. Pierre is working on a way to host several EQs for a single speaker model. When it's ready, we can host EQs with fewer bands. It's the aggregate boost that's important, not individual bands. The Edifier...

They don't really need a boost at 500-1000 Hz. Otherwise it looks fine.

I'm not shaming or insulting anyone. Just pointing out the fact that the music in question is generally not revealing of flaws in speakers and is therefore often used by salesmen at audio shows in an attempt to impress potential customers.

I.e., undemanding showroom music.
