Don't mean to be a smartass here, but wouldn't the full bandwidth speakers be the big picture and the auratones the closer look (@ the mids)? (Ok, I am a smartass

)
If anyone is interested, I tried some hifi speakers I had lying around instead of the tannoys, and it seems to me, that in my listening position most of the bass gets nulled, because I get almost the same washed out picture with little bass as with the tannoys.
So I think before I look at new monitors, I'm gonna experiment with speaker placement some more.
And yes, my room is already treated with bass panel traps, but the bass response is still very uneven. So that when I'm walking around with a sine playing, there's lots of cancelation and volume jumps going on.
