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.
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...
No need for eyeballing or guessing. These stats have already been calculated by @MZKM :)
3) Revel F328Be
4) SPL Specs:
-3 dB = 67 Hz
-6 dB = 48 Hz
-10 dB = 34 Hz
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...
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.
