Why aren't component active XOs more popular?

I have got no idea why they are not more popular
since they are superior in EVERY way.
Most of all they allow you to remove
inductors from the signal path; I'd rather have dozens of other
components then one inductor! They ruin everything:
they blur transients, shift phase and eat at least 50% of your
amplifier power as their minimum insertion loss is 3dB!

I could very well be wrong here, but, it is my understanding that untill digital crossovers arrived one could not get active crossovers to behave like 1st order passive crossovers. One may argue that having the large driver overlap of 1st order crossoves in large measure negates the point of active crossovers. Unfortunately one would then sacrafice the potential for time and phase continuity. I am hoping that the new generation of digital crossovers wil enable us to easily accomplish all the benefits with out (much?) compromise.

Errr...with a propper electronic crossover phasing doesn't get messed up in the first place so that is not really an issue! Remember it is the passive components of standard xovers that do all the messing up, remove them
and the problems disappear.
Electronic xovers are available with any slope you like if you really must have
a first order one or your driver demand, Bryston and LCAudio come to mind.
Many already contain delay to adjust timing differences between drivers.
Phasing can also be made continously variable if you want.
This is all possible in the analog domain so no need for convertors
and all the horrors they can produce.
Even other than the standard slopes should be possible.

Thanks for all the responses. As my bro-in-law explained it to me, the active XO is just another way to get the most out of an amp and also to get the most out of a system's environment by manually controlling which components receive which frequencies.

I'm new to high end stuff but after getting to know my equipment I think this would be a fun thing to do, especially with an entry-level crossover not being very expensive.

It's not so easy to add an electronic crossover after the fact to just any system. To be brief, first you need a speaker which truly has separate crossover paths for each driver, and not just two or more sets of terminals on each speaker. Second, you need to know, or discover, any number of characteristics of the passive crossover that comes built in to the speaker, for example, baffle step compensation, zobel networks, the optimal operating range of the drivers, plus the frequencies and slopes chosen by the manufacturer (hopefully) for good reason.

In terms of sound quality, it makes no sense whatever to with entry level, non diy electronics or speakers. In terms of being able to play around...maybe it makes sense.
