Many speakers are voiced to impress during a quick audition, often with a "smiley" EQ.
I'm convinced there are also brands/models for which the target market is older audiophiles who may need speakers with boosted highs in order to hear a balanced response. I've noticed many speaker response graphs where the highs at ~10kHz^ are boosted as much as 6db. Some of these graphs are for popular speakers from big brands that know full well how to design speakers for flat measurements.
