Christian,
Regarding 'vanity' speakers and also the surround delivery issues.
Kii Three's. They're a bit dear but I'm here to tell ya they are the way to go. I've been using them everyday all day for many months now. Of course they sound 'flippin' amazing'. But they are of great utility also. To my knowledge there is no others that actively direct the deep low end towards only the front - much like the infinite baffle effect of soffit mounted speakers. This means that you can pretty much set them wherever you like (for example, either close or far from the wall or even in the middle of a room that's not treated very well acoustically) and they still sound 'flippin' amazing'. So it's easy to pack them into a studio where you're recording and know that your mix will end up sounding like what you expected it to when you recorded the basics.
Each speaker has six 225W amplifiers (1,500W per box), tons of DSP to control many things - they sound like very, very improved Barefoots - but with much less 'hype' to them.
Oh, and they are
tiny. Yeah, tiny like a stick of dynamite. I got them to replace my ATC 150's in my surround setup!
I still have my Amphion Two 18's - which I also love and use for my rear speaks in surround mode - and a pair of ATC 25's.
Surround - mainly I've mixed surround for indies and some TV. The composer I work with a lot is doing mostly American TV now and delivers almost always in stereo.
I will only work in Quad now to deliver to dub. Everyone seems OK with that.
I hate the Center Speaker. I hate the Center Speaker.
I hate the Center Speaker. It only gets in the way of my monitors and besides I'm not a dialog mixer. It messes with my room topology. Phantom Center for dialog is just fine.
While I have a subwoof, dub mixers want to control that for FX any way. If you're Hans Zimmer and Alan Meyerson you can get away with dictating what part of your mix gets put into the dub. Most of the rest of us just deliver and pray.
Monitoring in Surround: When I used the ATC 150's I used the Dangerous ST/SR combo like I see you have. They sound most wonderful and have great features - except for the one - no Digital i/o. With the Ki Three's I wanted to use dig i/o. So I went to the Trinnov D-Mon 6. (It's also nice to use the digital outputs from my Mac into my main speakers.) Feel free to Google Trinnov. It has unparalleled audio correction. I also use the Kii Three Remote along with them.
In Quad, I use the Kii Three's for fronts and the Amphion Two 18's for rear.
They are a good size for your room. Since I've had to move 4 times in the last 4 years I've been putting my temporary mix room in rental homes. Currently I'm in a converted living room 14'x22', 9' high. Treatment is a pile of GIK panels and diffusors.
Here's what the Kii Three's look like in my room (chart from my Trinnov):
I've owned tons of speakers through out the years - you name it and I've either owned them or heard them.
I recommend you check out the Kii's. Feel free to PM with me any questions, comments or queries.
