What characteristics have motivated your choice?
Honestly: none!
Just read reviews from here to there!

For what purpose? 
Media: music, videos
Computer music: I use it to record, and for my mixes

What amp / What configuration? ...
I go out on an Edirol FA-66 or a sound card Realtek

Results 
They are really small, good build quality, connections, very well "designed" and on unpacking more confident than a PC kit!
I put 10 because that's what it's worth at this price!

SOUNDS

The frequency curve is sufficiently neutral? 
I do not know. Anyway, I use for my mix and I'm not "surprised" when I listen to it on other systems.

The stereo image is good?
Yes

The sound is clear and accurate across the spectrum? 
Yes, except on the lows, as I find a bit too "puffy" even without the booster bass. Besides this booster bass seems really rude!

The dynamic is respected? ...
I do not know. Anyway, I use for my mix and I'm not "surprised" when I listen to it other systems.

Results
I put 9 because that is what I got, better and better, so that I know (but I do not know much). The seller (Woodbrass) had discouraged me for the mix but I'm happy and to my (small) level that fits me perfectly!

Very good stuff in this price range, there are probably better for the audiophile or mix, but in a different price range!
For a little over 130 €, you are entitled to a reliable monitoring system, high quality, slim, pretty, strong and with full connectivity.
I put 10 here too
