Try adding peaks or valleys at ~1500 Hz, ~4000 Hz, ~500 Hz and hear the 'soundstage' changing right before your ears.
I am limited to Foobars stock EQ, I boosted at the closes freq possible. Firstly, decreasing them, didn't do much in terms of vocals, maybe just a slightly different sound.
1.5kHz (1.2kHz) this made the vocals sound different, hollow sounding but also craps on the rest of the instruments making them unnatural
4kHz (3.5kHz) sounds like an added artifacts, very distracting
0.5kHz (0.44kHz) every thing sounds like a winded tunnel
(1.2kHz + 3.5 kHz) slightly hollows the vocal and make the treble sparkly
(0.44kHz + 1.2kHz) this makes everything unlistenable
(0.44kHz + 3.5 kHz) slightly more listenable but its too obvious sounding EQed
I don't think positioning changed to the listenable ones at least. I only did quickly though.

If the natural FR response of said transducer is heightened upper midrange/lower treble, it is more likely to accentuate vocals but i wouldn't call it a rule by any stretch (graphs are graphs, ears are ears). The tilt of the above graphs is pretty different which will give a different sound than just the peaks/valleys.
Acoustic transducers yes
