And to cut a little more audiophile fuzziness out, I’d say I’d associate warmer with high cut and boosted upper mids. Which sounds like it would alleviate fatigue to some degree, perhaps be perceived as louder at a given spl. Tangentially, I built a little transmission line speaker, see Woden Designs Baby Labs pdf, I built the redeye, IIRC, the one that used the cheapest driver. The little 3 inch driver really rolls off above 10k, I’m missing a whole octave of the highest frequencies, and I’ve spent some time around planers and table saws and electric guitars, don’t have the best ears, but side by side with other speakers you notice. But anyway, the point is you notice, but it really doesn’t sound bad to lose a little high end. Something is missing, but it’s not ugly to listen to in the way some other speaker defects are.
