Richard Vandersteen has spent his whole professional life perfecting use of first-order crossovers to get exactly that unmistakeably musical voicing out of his designs. I had (still have/in storage) his flagship model from the 1980s, the Vandersteen 4s. I heard plenty of other speakers (a few in my home, many @dealers), but these were the ones that most approximated real, live music. Everything sounded so "right," so realistic.
Yes, first-order crossovers trade that last lick of ultimate dynamics & punch; and yes, they force drivers to work hard near their band-limits. But he chooses drivers & crossover points that work best with those cross-overs, and the man obviously knows what he's doing.
IMO it's lunacy to form a grudge against this or that design based on some theoretical prejudice.
