Best active speaker


I'm thinking about going the active speaker route. I'd appreciate some suggestions. Any active speakers using Class D? It's my impression that ATC is pretty much the leader in Active speakers. Also I need something with a nice cabinet - not a studio monitor.

I'm thinking about going further minimalist. Right now have a Transporter feeding two Bel Canto Ref 500Ms and Aerial speakers. I like that setup but you know, just thinking about trying something else for the fun of it.

Another factor you should look into is that ATC don't put a lot of emphasis on cabinet resonance control. Perhaps aside from the Anniversary 150s, all of their speaker cabinet sings to the drivers quite a bit which is quite baffling since they are so heavily constructed. ATC is definitely not one of those speakers that uses the latest computer modeled cabinet design topology.

The freestanding set of ATC's that Pink Floyd use have additional bracing inside. Many studios soffit mount them.

What really bothers me is ATC's treble extension

Indeed ATC focus on the range up to 12 KHz with soft dome tweeter (preferring damped type drivers over rigid types) - this design definitely rolls off earlier than some metal domes like the Be dome or designs with super-tweeter.
These are considered to be excellent:

As for the best, I would say the large ATC's.
