Opinions and recommendations on active loudspeakers

If you want ATCs and are worried about built-in amps you can just order them with the remote amplifier option.  They also sell passive speakers and stand-alone amps, and some active models that come with remote amps standard.

I have a decent size room so bought a pair of used dsp8000's. I heard the Kii3 at axpona and liked the modular idea. The Kef ls50 has an active version now that's supposed to sound even better than the original. It's true you're married to the amps when you go active, but i think that's a good thing. 

Powered subwoofer is a stupid idea too, Garcia.

Another vore för Kii Three. I heard them at a show and they impressed.

You could also go worth small speakers and an integrated  class-d amp, like Boenicke W5.

Hope you have great joy with all your tweeking. Some of us not so sophisticated just want to hear the music as close to how it was recorded as possible. A lot of active speakers are really good at that.
