@cosmicjazz Bryston and JL Audio make active crossovers. But as @erik_squires mentioned things can get pretty complicated if you really want to do it right, and I also strongly recommend (and offer) miniDSP in large part because of that. Inclusion of Dirac Live is also a big plus.
I imagine that active crossovers have become less popular at the high-end in favor of "full-range" speakers, inclusion of a subwoofer without a crossover, or more advanced solutions. Also, the vast majority of people with 2 or 2.1 setups are still purchasing home theater receivers which have built-in bass management.
