Why aren't there more active crossovers?

Loudspeakers divide their frequencies up with passive crossovers but more can be done if they are made active. Why aren't there more active crossovers in high-end audio? I am getting close to publishing my memoir! It's called 99% True and it is chock full of adventures, debauchery, struggles, heartwarming stories, triumphs and failures, great belly laughs, and a peek inside the high-end audio industry you've never known before. I plan a few surprises for early adopters, so go to https://www.paulmcgowan.com and add your name to the list of interested readers. There's an entire gallery of never before seen photos too.
