Thoughts on Active/Passive Speakers? Looking for pros and cons.

OP, you should listen to what @fiesta75 says about this topic and ignore the rest.

Active has a lot of limitations. And not only that the complexity is not worth it. For low end to mid fi, may make some sense. But high end will always be passive.

Oh really? Then can you please explain why nearly every professional audio rig you have ever heard (maybe you have not, which would make sense) at a live event uses active speaker systems?

Only in the US would an "audiophile" make such dubious claims without any experience.

The absolute best systems I have ever heard in people's homes have been active systems.

Active systems (if done correctly) are far superior to passive systems. Especially, and even in the "high end". Get with the times people.

@hilde45 the OP asked a question which @fiesta75 provided the best, most helpful, and technical explanation as to what the pros are for active systems.

Pretty much everyone else's comments were not useful as far as I could tell. Just trying to point out that many audiophiles are not helping OP with his actual question.

The only "pro" for a fully passive system is that you can use a single amplifier and thus save on expense. That's pretty much it. Everything else about a passive speaker is a "con" - even the best passive crossover is susceptible to noise and interference, let alone the fact that it is an inefficient use of the amplifier's energy.

OP, if you would like a great breakdown of the actual benefits of active systems, why they are used to record and mix the music you listen to, why they are used in live professional applications, and why so many loudspeaker manufacturers are beginning to integrate this principle into their current and future designs, read the last point on ATC's FAQ page:
