I have always been enamored with the idea of building a state-of-the-art active monitor. Yup, what a great product that would be.
Only, there's no room for customizing.
One of the things we as audiophiles do is tailor our sound systems to our tastes. If I am unhappy with the top end of my system I have a plethora of choices in amps and cables to change that top end.
Not so much with active loudspeakers.
So the challenge in an active speaker is getting something so flawless that no one pines for something better.
That's certainly a tall order but one I believe is actually possible.
Maybe someday.
